Musk & Barra Love Child: Battery “Super Pack” From A TMS Perspective

Crazy High C Rates!

It’s a conceptual marriage of the Tesla ribbon-style cooling system and the Chevrolet Bolt EV’s Prismatic-shaped pouch cells. We eliminate the bottom cooling plate.

Once we start cranking up charging rates, pack cooling becomes a big issue. We’re sure that Porsche is learning the hard way since they have promised some pretty high charging rates. Tesla’s Model 3 is the fastest charging EV to date. Model 3 owners are getting 460-480 MPH charging rates right now. With version 3 Superchargers, we are estimating charging rates up to 626 MPH and 157 kW (2 C). The next step is Porsche’s Taycan 800 V charging system, which promises 730 MPH charging (2.4 C).

We’re obsessed with knowing what Porsche will do to get rid of all that heat.

Based on our analysis, they are going to have a tough time doing it with just a bottom cooling plate (see “A little secret GM isn’t telling us about improving the Bolt EV Battery”.

The Bolt EV has a bottom cooling plate design and it is somewhat limited in its cooling and charging ability. Tesla’s cooling ribbon design seems to be about the best there is right now, but how can it be improved?

Enter our new concept in cooling schemes:

A marriage of prismatic cells and Tesla’s cooling ribbon.

At 3C, the Tesla Model 3 could pull down 939 MPH charging rates.

Not too shabby. Sign me up.

Elon Musk Admits Paint Is The Current Model 3 Bottleneck

Some Tesla Model 3 paint issues are leading to building a whole new car.

A Model 3 reservation holder tweeted to Tesla CEO Elon Musk complaining that he still hasn’t received his car. This is still the case for many people, however, this particular owner-to-be was already set up to take delivery. His VIN was canceled due to problems with the car’s paint. At this point, according to the Twitter user, Tesla is unable to confirm when a replacement will be ready.

It’s no surprise that paint is one of the remaining bottlenecks in the Model 3 production process. However, the fact that Musk admitted it, went so far as to say that they’re even having to rebuild entire cars, and elaborated about particular colors, makes it an interesting share. On the positive side, it’s becoming increasingly clear the Tesla is laser-focused on making sure the Model 3 is right. While there may have been multiple issues early on, it seems the automaker has worked most of them out and is not going to settle for anything unacceptable.

More clarification

This may mean some people begin to experience more delays. Hopefully, it also may mean that their Model 3 will be bordering on flawless.

Are you surprised that Tesla is having to build entirely new cars due to paint issues? How is the paint on your Model 3? Share your thoughts and wisdom with us in the comment section below.

Range: 310 miles; 136/123 mpg-e. Still maintaining a long waiting list as production ramps up slowly, the new compact Tesla Model 3 sedan is a smaller and cheaper, but no less stylish, alternative, to the fledgling automaker’s popular Model S. This estimate is for a Model 3 with the “optional” (at $9,000) long-range battery, which is as of this writing still the only configuration available. The standard battery, which is expected to become available later in 2018, is estimated to run for 220 miles on a charge.

Fact of the week: Internal combustion cars still waste 70 to 88 percent of energy

Energy losses from internal combustion car [Source: DOE]Conventional cars manage better fuel economy every year. According to the latest Department of Energy “Fact of the Week,” though, their efficiency ranges from a-little-better-than-before to still-abysmal. This week, the DOE noted that of all the energy splashed into a conventional car’s gas tank, only 12 to 30 percent actually goes to move the car…

CNET Tests Tesla Model 3 Performance Track Mode

Tesla’s new ‘Track Mode’ on Model 3 Performance put through its paces

The 2018 Tesla Model 3 Performance is one heck of a quick car. Thanks to its dual motor configuration and instant torque, the vehicle can sprint from 0-60mph (0-97kmh/h) in just 3.5 seconds (officially, though tests have proven quicker).

While sheer straight line performance may be the headline that is most often associated with the Model 3 Performance, the package also contains some track-oriented items. These include somewhat stickier Michelin Pilot Sport 4S tires, a set of Tesla-branded Brembo brakes, a sport suspension and carbon-fiber trunk lid spoiler. But, it seems that the U.S carmaker was not done playing around with the Performance Upgrade package. According to CNET, the new Track mode software is still in the works to complement the beefed-up hardware.

The Track Mode builds on the swift dual-motor acceleration of the Model 3 and its Performance Upgrade package. It uses a few carefully chosen software tweaks that are designed to optimize the performance and engagement of the vehicle on the race track. In a nutshell, the package aims to make the Model 3 even more fun.

It does this by shuffling power between the front and rear motors in dynamic track situations more freely, allowing the EV to rotate dynamically. With the newly acquired mode, it’s possible to even drift the car with ease. Furthermore, the software is also constantly monitoring the traction between both axles and is able to instantly add torque to either motor, all in order to keep the drift from becoming a spin, and eventually, a crash.

Tesla Model 3 Performance

Additionally, putting the Model 3 through its paces on the track uses a lot of energy. Hence, the Track Mode increases the braking regeneration in order to reclaim the maximum energy when slowing or cornering. While the effect may be dramatic deacceleration (which is definitely a good thing), it also helps keep the standard brakes on the car cooler during extended sessions. In turn, this negates any possible braking fade. Finally, the dynamic braking aids in cornering stability, as the regenerative braking system biases the regen-braking power between the front and rear ends in mid-corner.

However, the standard Brembo brake system also plays a key role in both braking and dynamic stability. It not only shaves off impressive amounts of speed during those fast & hard corner entries but also improves the car’s mid-corner stability control. The standard brakes allow the dual motors’ open differentials to operate like brake-based limited slips. In turn, this allows for much more precise power delivery when accelerating out of the corner, making for faster turn exits and allowing for more speed in dynamic track conditions.

The final improvement of the Track Mode is the powertrain cooling. With this, the powertrain cooling is kicked into overdrive, allowing the Model 3 Performance to be thrashed on the track more, by allowing a more efficient use of the battery pack’s charge and the electric motors. You can even pre-cool the system if you activate it sometime before your track session, but also, continue cooling your powertrain on the way home.

Just a few days ago, as part of the Monterey Car Week, the journalists from the magazine got to witness this upgraded Performance Upgrade package firsthand. Even though this was a pre-release version of the Track Mode, the impressions garnered by the publication on an autocross cone course were impressive.

You can read the full report on the Tesla Model 3 Performance Track Mode right here. Hopefully, we’ll get to see a video of the car performing on the track with this mode quite soon.

Efficiency Matters And That’s Where The Jaguar I-Pace Falters

Still won’t deter most buyers

We love the 2019 Jaguar I-Pace. It’s electric (of course). It’s attractive. It’s quick on its feet. It has a premium feel inside. The list of rave reviews is long and enthusiastic. But, it also has some faults. One of these has gone mostly unmentioned, but considering the environmental concerns of at least some consumers considering the Big Cat, it is worth noting. The problem, in a word, is efficiency. Or the lack thereof.

Wired recently got its hands on a copy of the British crossover. Their concern wasn’t so much about its exaggerated energy usage so much as it was about range, though of course this is directly correlated. The author got 41.6 kWh per 100 miles on a route that saw the Tesla Model 3 return a reading of 26 kWh per 100 miles, which is its precise EPA efficiency rating. Now, we don’t know why, exactly, efficiency is rated as kWh per 100 miles instead of the obviously-more-sensible miles per kWh, but that is what the government has proclaimed to be the proper metric, so pipe down. We digress…

Of course, being smaller, sleeker, and lighter, the Tesla Model 3 is bound to be more efficient, so perhaps we should compare it to something bigger, like the Model S 100D. That car is actually more than 200 pounds heavier than the I-Pace yet uses up only 33 kWh to travel 100 miles (according to the EPA). That’s 5 kWh every 100 miles, or 5,000 kWh over 100,000 miles. Sure, the Model S likely slips through the air more easily, as it sits 4 inches lower and has a lower drag coefficient  — .24 to the Jag’s .29 — but it’s still a significant difference.

So, how does it stack up against something a little closer to its SUV-like shape? Well, until we see what the Audi e-tron returns, the Tesla Model X 100 may be its closest competitor. Although it sits a full five inches higher and weighs as much as 800 lbs more, the SUV from Tesla is still about 2.6 kWh per 100 miles more efficient. That’s kind of amazing.

While it may be a while until we can figure out where the losses are coming from, Jaguar customers can at least be assured that any extra heat generated from the drivetrain’s inefficiency is managed quite well and won’t impact the car’s performance. And who knows? Perhaps the British automaker can take a page from its competitor’s book and make improvements to that figure in an over-the-air update. We shall see.

Tesla Makes New Hires To Improve Delivery Experience

Tesla service centers continue to be overwhelmed, but improvements are reportedly on the way.

As we reported last month, the Tesla Model 3 has begun to strain resources for the all electric automaker. U.S. deliveries this quarter will be massively increased over 2017. However, the numbers of employees and service centers have not grown at the same pace as sales.

With the company’s amazing growth, these employees are unfortunately being stretched thin. In early August, many disappointed owners were informed by their Inside Delivery Advisors (IDA) that their vehicles did not pass quality check following a ‘strict inspection’. Based on statements by owners, most of the delays from July and August seem to be related to paint issues.

Elon Musk this week addressed the paint issue specifically:

Ultimately, this is the correct policy to make sure the vehicle does not reach the owner unless it meets a high standard of quality. But communication between Tesla and buyers will also need to improve.

Buyers in Texas that have paid for the car in full are often completely in the dark about when their vehicles will arrive. Some new owners are finding their deliveries delayed not once but multiple times. Occasionally these delays have occurred hours before scheduled delivery. This makes it difficult to plan for insurance, financing, and private vehicle sales. Typically, their IDA is unable to provide much in the way of guidance.

Tesla Model 3

Changes should be coming soon to the delivery process.

Despite all of these issues, InsideEVs expects yet another record month for Tesla deliveries in August. While some owners might be displeased with the buying process, it is not significantly deterring them. Once the car arrives, the problems usually fade into the background. But Tesla does seem to be working towards addressing complaints.

They have already begun to make some changes to improve the experience at service centers. The company plans for 80% of minor repairs to be handled by Tesla’s mobile service. Tesla is also attempting to reduce the delivery process to the press of a button.

Having large regional locations that focus only on deliveries would go a long way towards improving the entire process. Additional service centers and employees will also be necessary to smooth out the rough edges.

According to a report from Electrek, Tesla appears to be making moves toward some of these changes. Under the new Director of Field Delivery Operations, a restructuring is occurring to separate delivery and sales. East, West and Central delivery managers have been appointed, in addition to new delivery managers for, localized regions such as Texas.

The automaker is also looking to hire a large number of new employees. Over 100 delivery related positions are currently listed on Tesla’s career page. Many of the open positions are at the Fremont delivery center.

Hopefully this, in addition to the newly appointed delivery managers, is a sign of increased investment in the delivery center concept. As the Model 3 continues to grow in numbers, the rest of the country would benefit from a setup similar to Fremont and Marina Del Ray. Not only would this speed up the process for service and deliveries, but it should improve communication as well.
