Self-driving vehicles could reach critical mass sooner than expected

Sponsored by Black & Veatch

A future where it’s cheaper to use a self-driving vehicle ― whether for transporting goods or people ― is driving a mobility revolution. And that future may be here sooner than many realize.

Transportation is in transition. City populations are rapidly growing, and residents are using rideshare and public transit more often. According to the new eBook, Autonomous Vehicles and Our New Mobility, the increase in Transportation as a Service (TaaS) is driving a future where individual vehicle ownership may no longer be as convenient, or cost-effective, as shared ridership.

The shifting mobility also impacts the movement of goods. Driver shortages, safety and efficiency are issues facing companies that haul cargo on roadways, whether long distance in heavy-duty semi-trucks or last-mile deliveries in medium-duty trucks and vans.

The rise of autonomous vehicles could mean billions in safety, collision repair and operations savings, not to mention reductions in greenhouse gas emissions with AVs primarily built on the electric vehicle (EV) platform.

Experts predict the AV tipping point, when AVs are more efficient than owning and operating vehicles, could happen within the next three to five years.

Black & Veatch’s new eBook was developed to help all stakeholders understand and plan for AVs. The free download provides an analysis of market and societal factors accelerating AV adoption and the infrastructure requirements needed to enable this transportation evolution.

As with all emerging technologies, partnerships will propel autonomous vehicles, and through timely collaboration, the industry will be able to plan and establish supportive charging, electric utility, and communication networks. Combined with a regulatory framework that encourages innovation, these essential digital infrastructure networks will enable the most significant transportation evolution to hit the roads in several decades.

Top causes of failure in power semiconductors

All electronic devices eventually die, and the failure can be quite spectacular if suitable foresight and care was not employed during the design and construction phases, especially if the device handles high power or is supplied by a large battery. It should go without saying that both conditions apply to much of the electronics inside an EV, so a closer look at where and how power electronics fail and how to minimize the collateral damage will be the focus of this article.

Although there are myriad precipitating or apparent causes of failure, the ultimate cause is usually thermal in nature; that is, overheating. The only real exception is failure due to overvoltage puncturing an insulator, such as the gate oxide layer in a MOSFET or IGBT. Applying too high a voltage across a reverse-biased or turned-off semiconductor (PN) junction will cause it to start conducting through a process called avalanche breakdown, but it might be surprising to learn that no harm will result as long as current is limited. This is how most Zener diodes work, actually (those with a breakdown voltage above 4 V or so), but aside from Zeners and a few specialized devices/circuits typically used to create short, sharp pulses, avalanche breakdown is an unwelcome – and unplanned-for – phenomenon. Consequently, if a switch or diode undergoes avalanche breakdown, it frequently fails a few nanoseconds later from extreme overcurrent.

The most common cause of avalanche breakdown in power electronics – besides overvoltage on the supply line – is from the spike produced during turn-off by any stray (or “unclamped”) inductance in between the switch and the input capacitor (or between each switch in an inverter leg). This spike is produced because inductors resist any change in the flow of current through them, and while the inductances involved here are (or should be!) very small – on the order of a few tens of nanohenries at most – the currents can be quite high and the switching times quite short.

The actual equation that describes the voltage produced by an inductor experiencing a change in current is V = L * (dI / dt), where V is in volts, L is in nH and dI / dt is the change in amps per nanosecond. Given that a single wire in free space has an inductance of about 8-10 nH per cm, and that the voltage spike will be 1 V for every 1 A / 1 ns per 1 nH of inductance, it’s apparent that serious attention must be paid to minimizing the stray inductance by bringing the forward and return conductors as close together as possible (which cancels out the magnetic fields – and therefore the inductance – from each) or else resort to more complex circuits to either recycle the energy stored (e.g. resonant operation or active clamps) or to dissipate it as heat in passive snubbers. While lengthening the turn-off time will reduce the magnitude of the spikes, it also increases the switching losses, and if taken too far will also result in device failure; a case in which the cure is worse than the disease. Finally, degradation of the input capacitor – that is, a loss of capacitance and/or an increase in its Equivalent Series Resistance (ESR) – can also cause the turn-off spikes to increase over time; this is a particular issue with electrolytic types, as they literally dry out with age or use.

Overcurrent is another proximate cause of failure, but unlike overvoltage, in which there is a clearly marked delineation between what is tolerable and what isn’t, current rating is a much more nebulous parameter. This is because the current rating of a semiconductor mainly depends on how effectively heat can be removed from it. Other effects such as the number of charge carriers available, thermal inertia, etc. affect the ultimate current permissible through a semiconductor device, but at timescales longer than a few minutes you can just about push as much current through it as you want so long as you keep it from getting too hot. The key parameter in the datasheet to check is the thermal resistance from the junction to either the case (you specify the heatsink) or the ambient (they specify the heatsink) and the maximum junction temperature allowed, which is usually 100° C (though it can be much higher for newer silicon carbide devices). Even reputable manufacturers can play fast and loose with all the specs involved here, so it definitely pays to run a few calculations as a sanity check before spec’ing a part.

For example, one 1,200 V / 600 A IGBT datasheet specifies a thermal resistance from junction to case of 0.049° C / W and a maximum voltage drop of 2.40 V at 100° C, so this device can theoretically handle 637 A as long as the case is kept at 25° C. To actually achieve the datasheet spec of 600 A while keeping the junction below 100° C at an ambient of 25° C, however, the total thermal resistance from junction to ambient cannot exceed 0.0521° C / W. Given that the IGBT already uses up 0.049° C / W of that in the junction to case, the heatsink can’t contribute any more than 0.0031° C / W of additional thermal resistance. While this isn’t technically impossible to achieve with an exposed-pipe liquid-cooled heat exchanger with sufficient coolant flow, it definitely qualifies as “heroic measures required” (especially since losses from switching haven’t been considered, much less operating at an ambient higher than 25° C). As a heatsink with such vanishingly small thermal resistance tends to cost a lot, while competitive market pressures steeply penalize designs that are too conservative, the best compromise is to monitor the temperature as close to the junction as possible – the aforementioned device includes a thermistor right next to one of the IGBT dice inside – and start derating the allowed current once temperature climbs above a certain point.

The other effects that come into play at even higher currents (and much shorter timescales) are bond wire vaporization (i.e. acting like a fuse), desaturation, current crowding and other safe operating area (SOA) violations. Bond wire vaporization is fairly self-explanatory: bond wires are the very small-diameter wires that interconnect the semiconductor die or dice to external terminals so they are very much like the fuses they so resemble (failure from repeated thermal cycling will be addressed below). Desaturation is a phenomenon in which the voltage drop across a switch that is otherwise supposed to be fully on starts rising sharply as if it were only partially on. While this term is most commonly applied to IGBTs (or other bipolar devices) because they exhibit the effect most strongly, it can occur in any semiconductor, and is the result of running out of charge carriers (“holes” in p-type material; electrons in n-type). Desaturation is especially pronounced in bipolar devices (like IGBTs) because voltage drop in them remains fairly constant over a wide range of current – usually in the range of 1.5 V to 2.5 V for modern IGBTs – but increases to 7 V or more at some level of overcurrent (usually >3x rated current). The voltage drop in unipolar (or “majority carrier”) devices such as MOSFETs is basically ohmic in nature until desaturation occurs, so it will likely already be quite high by the time the device truly enters desaturation (and it will have long since failed from overheating, too). The sharp rise in voltage drop during desaturation in IGBTs makes it a convenient proxy for detecting overcurrent and short-circuits in them (less so for MOSFETs), but the protection circuit needs to act fast, because a steep increase in voltage drop times an already excessive current means extraordinary amounts of heat are being generated in the junction. Consequently, even those IGBTs which claim to be “short-circuit tolerant” need to be turned off within 10 microseconds of entering desaturation (while those that don’t make such claims might survive such abuse for 1 µs at most).

Current crowding is basically desaturation that is localized to the area surrounding the gate contact(s), and it occurs to some extent every time an IGBT is in the process of turning on or off, due to the time it takes the change in operating state to propagate throughout the die (this effect is virtually non-existent in MOSFETs). Current crowding used to be a major problem in the older Bipolar Junction Transistor (BJT) technology that predates IGBTs, but the use of massively parallel and cellular construction – splitting one big switch up into many hundreds of smaller switches in parallel, basically – has nearly eliminated it.

A related problem is the SOA violation, which occurs when the product of the voltage drop across a device and the current through it exceed the safe operating area. When the switch is fully on, the voltage drop across it is very low, and while the switch is off the current through it is zero, so dissipation is low or zero, respectively. During the transition from each state, however, the voltage drop is high, while current might also be high – the device is acting more like a resistor than a switch. For example, a switch that is supplied by 300 V at a current of 100 A experiences a worst-case instantaneous power dissipation of 30 kW right before it fully turns off. When integrated out over the course of a full switching cycle the average dissipation loss from switching should be quite low, but that assumes that the transition time is a small fraction of the cycle time (a rule of thumb is to aim for transition time in the range of 0.5-1% of the period). This is why you don’t want to make the switching times any longer than necessary (nor increase switching frequency arbitrarily). The graph of allowable voltage drop vs current is called the safe operating area for the device, and while modern MOSFETs and IGBTs generally have “square” SOA curves – that is, can tolerate both maximum current and voltage at the same time – they also are infamously intolerant of operation in the linear region (i.e. like a resistor).

The last major cause of failure is thermal fatigue, which can affect the bond wires, semiconductor dice, the solder which attaches the dice to the heat spreader, the ceramic insulator used between the heat spreader and baseplate, etc. Thermal fatigue occurs when there are mismatches in the coefficients of thermal expansion of the various layers bonded together (die, substrate or heat spreader, insulator, baseplate, solder, etc) which are then subjected to temperature variations. The differences in the rate of expansion of each layer induces mechanical stresses proportional to the change in temperature. If the temperature swing is too wide and/or there are too many hot/cold cycles, then cracks in any of the layers, or voids in the solder, specifically, can develop. Thermal fatigue is the one failure mode guaranteed to strike down a power semiconductor if nothing else gets to it first. While there are simple solutions to this problem – such as the springs that Semikron uses to press the dice, heat spreader and insulator against the baseplate in their lower-power modules – they invariably suffer from a much higher thermal resistance and/or assembly cost. Consequently, this is one failure mode we all have to live with, but with good design and careful assembly the inverter, charger, etc, in an EV should outlast the batteries, motor and most of the moving parts.

BYTON Provides Look At MByte Electric SUV Production Model At CES

See inside the production version of the electric SUV.

If BYTON is able to adhere to their previously announced timelines, they are less than a year from the start of production for the all-electric M-Byte SUV, the first vehicle to come from the new automaker. With that in mind, we expect 2019 to be chock full of announcements and reveals, since the M-Byte vehicles BYTON paraded around the world in 2018 were in concept form.

BYTON’s Concept M-Byte interior. The production interior is definitely similar, but much more refined.

So it’s no surprise to us that BYTON decided to show off some pictures of the production-intent interior of the upcoming SUV. What may surprise some of our readers, is that BYTON is sticking with the large display screen, that pretty much stretches the entire length of the dashboard. BYTON representatives had assured us from the start that was their intention, but there were those that doubted whether or not that would find its way into a production vehicle.

BYTON’s M-Byte SUV production interior

The M-Byte SUV, as well as the K-Byte sedan, (arriving about 2 years after the M-Byte) is available in 71 kWh and 95 kWh battery configurations. The smaller battery will offer approximately 250 miles of range, and with the larger battery, range is estimated to be 325 miles. BYTON hasn’t commented on which range measuring standard they are using, but we believe it’s most likely the WLTP, so EPA range figures would likely be slightly less.

BYTON is also showing off their UI / UX technology here at CES, and is one of the aspects of the vehicle that their team seems most proud of.  There are multiple ways to interact with the M-Byte, including gesture and voice control as well as physical buttons.

We’ll be sitting down with the BYTON management team here at CES in the few days, and will bring you more insight into the company’s plans for 2019.

  • The 7-inch Driver Tablet pioneered by BYTON will be at the center of the steering wheel just above the driver airbag, serving as one of the main interfaces for the driver to configure the vehicle and interact with the SED.
  • An 8-inch BYTON Touch Pad has been added between the driver and the front passenger seats on the production model, enabling the front passenger to control the SED and enjoy the same interactive experience as the driver.
  • Rear passengers have access to independent rear-seat entertainment screens that also share content with the SED.
  • The front seats can be rotated inward 12 degrees, to create a space that is more convenient for passengers in the car to interact and communicate with each other when not in motion.
  • The dashboard features a new wraparound design with air conditioning vents, gear selector, and other hard buttons located in the center along with a driver monitoring system to ensure safety during assisted-driving modes.
  • Multiple interaction modes with the vehicle will be offered including voice control, touch control, physical buttons, and gesture control.

 Enhanced User Experience & Personalized Mobility

BYTON users will have access to BYTON Life, an open digital ecosystem that connects applications, data, and smart devices. BYTON Life features advanced machine-learning capabilities that analyzes the user’s schedule, location, preferences, and application data to provide intuitive support such as scheduling reminders, online shopping tasks, remote charging management, and more. It can recognize voices of different users and sounds from different directions in the car. In North American and European markets, BYTON has been cooperating with Amazon Alexa to jointly develop voice control. In addition, BYTON has also invited software developers from around the world to join BYTON’s ecosystem and explore new possibilities for applications and content on BYTON Life’s open platform.

Full-scale vehicle testing ahead of production

The production version of the BYTON M-Byte is slated to debut in mid-2019, with mass-production starting at the end of the year. To achieve this, vehicle testing continues in full swing to achieve the highest safety and quality standards of China, the US, and Europe. Meanwhile, BYTON’s Nanjing plant is on-track to be completed this year and will be equipped with cutting-edge production equipment from leading global partners such as AIDA Engineering of Japan, and KUKA and DÜRR of Germany. The company is also working with key strategic investors FAW and CATL, and world-class suppliers Bosch, BOE, and Faurecia to integrate the world’s best technologies and resources into its products.

“We have made solid progress in the construction of our Nanjing plant and prototype vehicle testing,” said Dr. Daniel Kirchert, President and Co-Founder of BYTON. “This is a vital year for BYTON and our global team is sparing no efforts to achieve our goal of volume production.”

Electric Cars Battery Capacity and Efficiency: In-Depth Analysis, Graphs

There are many factors to consider when buying an all-electric car (BEV)

Some of the most important ones are:

• Wells-to-Wheels carbon emissions

• Battery Capacity in kWh

• Battery efficiency in miles/kWh, MPGe, kWh/100-miles. I prefer miles/kWh since kWh is what I pay for and it is easy to memorize.

• Range in miles, which is a function of battery capacity and efficiency

• Price

This article is an attempt to quantify the first five of these factors.

The following graph shows how kWh/100-miles and MPGe are related to miles/kWh:

The value of kWh/100-miles is useful to calculate how much energy in kWh is required to travel a specific distance in miles. The value of MPGe (MPG-electric) is useful to compare the efficiency of a BEV to a gasoline car’s MPG. MPGe is calculated using the EPA number that one gallon of unleaded regular gasoline when fully combusted produces 33.7 kWh of heat.

The following graph shows how range (miles) varies with battery capacity (kWh) for seven values of miles/kWh:

Range can be calculated as Range(miles = Battery-Capacity(kWh)*Miles/kWh. Unfortunately, auto companies often do not list range and/or efficiency for their BEVs. Some do not list either. However, reviews by car reviewers often list one or both. But, sometimes the range listed is for the European Driving Cycle (NEDC) rather than the U.S. EPA Driving Cycle. The NEDC range value for a specific BEV is always considerably larger than the EPA range, which means that the miles/kWh is always larger.

To complicate matters the European Union, Japan and India have defined another Worldwide Harmonized Light Vehicles Test Procedure (WLTP), which value lies between the NEDC and the EPA value. It is often not clear in a BEV review article which of the three test numbers is given. So the range numbers in the following graph for range vs battery-capacity for several BEVs may not all be EPA values:

*Note that BEV efficiency (range) varies widely for high battery capacity

Union of Concerned Scientists has calculated the 2016 equivalent MPG for a gasoline car to equal the driving carbon emissions of a typical BEV in various regions of the U.S. The sales-weighted average for the U.S. is 80 MPG, which will increase if electric-power sources become more emissions free. The different regions vary from 38 MPG to 191 MPG. (See the map.) Of course, if you have enough solar panels on your house, the gasoline equivalent MPG is very much higher.

Union of Concerned Scientists have calculated the “Wells-to-Wheels (WtW)” carbon emissions of average gasoline cars and average BEVs in the U.S.. It was found that BEVs have about one-third WtW of gasoline cars for the U.S.

Here is a graph that shows driving costs for BEVs:

The dashed line (3.5 miles/kWh) is my estimate for the average BEV in 2018.

The average cost of electricity for the last several years has been about $0.12 (vertical line).

The average (dashed line) crosses the vertical line at about $0.035/mile.

Compare to this graph that shows driving cost for gasoline cars:

The dashed line (27.4 MPG) is for the average gasoline car in the U.S. for 2016.

The average cost per gallon for the last several years I estimate at $2.50 (vertical line).

The average (dashed line) crosses the vertical line at about $0.09/mile.

New Study Shows Which Countries Lead & Trail In Electric Car Adoption

The variation between countries is significant, indicates a new study by GoCompare.

The case example pointed out below is for Canada, but the interactive graphic allows for you to pick and choose what you’re searching for.

There are 23,620 electric cars in Canada, ranking the country 13th out of the 30 International Energy Agency (IEA) member countries analysed for the research. There are more electric cars in countries such as Norway, the Netherlands, Sweden, Belgium and Switzerland – all smaller than Canada.

Canada, the second largest country in the world by area, had 5,841 charging points for electronic cars making it the ninth best equipped. In comparison, the tiny Netherlands comes third with 32,875 charging points. This means Canada has the seventh worst charging point network with just 0.56 charging points every 100 kilometres, compared to 23.25 in the Netherlands.

All charging points and petrol stations combined, the proportion of charging points in Canada is just 28 percent, the seventh lowest among the IEA member countries. This means 5,841 charging points against 15,000 petrol stations. In the best-performing Norway the proportion of charging points is 87 percent, while China comes third with 68 percent.

The below graph is available for all IEA member countries here

What we analysed

GoCompare set out to see which countries are best-prepared for the future of electric cars by looking at the following factors:

  • The number of publicly accessible charging points per kilometre of each country’s road network.
  • The number of petrol stations vs the number of publicly accessible charging points in each country.
  • Each country’s electric car stock (including battery electric cars and plug-in hybrid cars) vs its number of publicly accessible charging points.
  • The number of normal power* and fast power** charging points that are publicly accessible.

*normal power charging points mean > 3.7 kW and ≤ 22 kW
**fast power charging points means AC 43 kW chargers, DC chargers, inductive and Tesla Superchargers

Does Endless Big Auto EV Hype Help Or Hinder Tesla?


While they’ve been slow to cut the umbilical cord from gas (and diesel) powered cars, Big Auto is starting to open up to vehicle electrification. This sparked speculation, especially from financial pundits, that Tesla’s days were numbered. Would Big Auto’s newfound interest in clean cars squash the Silicon Valley upstart? Or, would their impact draw more attention to the electric car innovator.

*This article comes to us courtesy of EVANNEX (which also makes aftermarket Tesla accessories). Authored by Matt Pressman. The opinions expressed in these articles are not necessarily our own at InsideEVs.

Regardless, the EV segment, once a small industry niche, is destined to expand. Stephanie Brinley, IHS-Markit’s principal automotive analyst tells Consumer Reports, “The more choice you have, the more attention gets drawn to the segment, and the more opportunities customers have to see it as something that’s attainable, that’s viable.”

And while Big Auto’s EV progress remains sluggish, there’s a new “crop of high-performance luxury EVs that won’t wear a Tesla badge. These new electric cars and SUVs are from traditional manufacturers, including Audi, Jaguar, Mercedes-Benz, and Porsche, and they’re entering a market that some analysts predict will explode in the next few years—with sales increasing sixfold in the U.S. by 2025.”

When asked for comment, a Tesla spokesperson repeated a statement the company made in 2016 when the Jaguar I-Pace EV was first announced. “Every compelling EV on the road is a win for Tesla,” the spokesperson wrote to CR. Some speculate, as JFK once famously said, “A rising tide lifts all boats.” Could the same principle apply to a flood of new electric cars?

Regardless, Tesla maintains some hard-to-beat street cred in the EV world. “There’s no question that they made EVs cool,” says Chelsea Sexton, an industry analyst and EV advocate. In addition, “Most of these new luxury EVs from traditional manufacturers can’t match Tesla’s promise of 300 or more miles on a single charge, but… [they’re] hoping to capture something similar to Tesla’s magic.”

However, it could prove difficult for legacy automakers to take down Elon Musk. “Despite spending virtually no money on traditional advertising, Tesla is the best-known electric car manufacturer in the world, according to a 2017 survey from market research firm Dalia Research.” And obviously, “Tesla’s other big advantage in the EV space is its network of 644 Supercharger 480-volt fast-charging stations in the U.S. and Canada.”

But right now, “Tesla doesn’t currently have the production capacity to meet that potential surge in demand, Brinley said, and so that opens the door wide for these new offerings.” In turn, “To support the cars, automakers are building out [albeit slowly] a nationwide charging network to rival Tesla’s own Supercharger system.” And they’re also working hard to reach “technology levels that Tesla, headquartered in Silicon Valley, has already reached.”

In the end, Brinley told CR that Tesla does indeed stand to gain as other brands debut their EVs. “The more choice you have, the more attention gets drawn to the segment,” she says. “If you expect EVs to be a larger part of the marketplace, eventually other players have to come in,” she says. “Tesla can’t supply the world.”

Tesla Model Y Rumormill Reignites: $40,000 Base, AWD Standard + More

Or perhaps just $35,000, though we doubt that.

The upcoming Tesla Model Y has yet to be officially revealed, but now we may have some new details to share. Do you believe a starting price of $40,000?

The Model Y rumormill is again churning and, though we can’t confirm any of these new details, it seems the Model Y won’t disappoint.

All that’s officially known of the Model Y is limited to the teaser above and some hints from Musk here and there.

According to Tesla, the Model Y will be largely based upon the Model 3. This means its cost to develop should be on the lower side, though that doesn’t imply a low price tag necessarily.

The newest rumors (see embedded tweet below) indicate a base price of $35,000 to $40,000. Additionally, the minimum range is expected to be 250 miles.

What’s perhaps most interesting though is the Autopilot information contained within the Tweet:

  • Autopilot hardware 3.5 with more cameras and Tesla-designed radar
  • Level 4 full self-driving at launch

As with any unconfirmed rumors, take this with a grain of salt.

Previous rumors indicated Model Y would be a 3-row crossover, though that seems a bit questionable too.

Tesla announced on January 4 that Chinese consumers are allowed to place an order for optional configuration sets of the Tesla Model 3’s High-Performance All-wheel Drive (AWD) version and Long Range AWD version on Tesla China’s official website and at Tesla’s experience centers in China from now on.

The two versions of the Model 3 are expected to be handed over to consumers starting from March, 2018, said the EV maker. The prices of the High-Performance AWD version and the Long Range AWD version have been reduced to RMB560,000 and RMB499,000 after China said on December 14 it would suspend some tariffs on vehicles and auto parts imported from the U.S..

The Tesla Model 3 is famous for its ultra-long battery endurance. The ranges for the High-Performance version and the Long Range version reach up to 595km and 590km respectively under Chinese standard. Meanwhile, the EV manufacture has deployed over 1,500 supercharging piles and more than 1,850 destination charging piles across 170-plus cities in China to support the charging needs for Tesla’s users.

Tesla said on January 2 that it produced a total of 86,555 vehicles in Q4 2018, achieving an increase of 8% over the previous quarter. Specifically, the outputs for the Model S and Model X totaled 25,161 units and for the Model 3 amounted to 61,394 units.

The company saw its Q4 deliveries reached a new high of 90,700 units, among which the deliveries of the Model 3 climbed 13% over the Q3 to 63,150 units.
