A new whitepaper details the advantages of the various resin impregnation methods and automation solutions for electric motors, including a look at dipping, vacuum potting, and trickling. The quality of the insulation in electric drives determines, among other things, the durability and efficiency of the motor. Trickling in particular—with the right dispensing technology—offers great potential when it comes to the optimization of individual production steps.

Factorial Energy has introduced what it says is the first 40 Ah solid-state EV battery cell.
The Factorial Electrolyte System Technology (FEST) is a proprietary solid electrolyte material designed to enable safe and reliable cell performance with high-voltage and high-energy-density electrodes. Solid electrolytes like FEST are considered safer than conventional lithium-ion technology, as they replace the combustible liquid electrolyte with a more stable solid-state electrolyte that suppresses dendrite formation on lithium-metal anodes.
“Factorial’s solid-state battery technology offers the performance, safety, scalability, and commercial readiness needed to move the needle of EV adoption. We are thrilled to be the first to reach the 40 Amp-hour benchmark for a solid-state cell,” said CEO Siyu Huang.
Factorial says several automotive partners are currently evaluating its technology, with the intent of integrating FEST into their existing supply chains.
“Our batteries are unique because they achieve the broadest range of OEM performance requirements while offering superior energy density, safety and scalability,” said Joe Taylor, Factorial’s new Executive Chairman. “Our technology can be easily integrated into existing lithium-ion battery manufacturing infrastructure, which makes Factorial an immediately viable partner for every automaker pursuing EVs.”
Today, Stellantis (the company formerly known as Fiat-Chrysler before a merger with Peugeot) sent me something really cool to review: a 2021 Jeep Wrangler 4xe (pronounced “four by E”), in Rubicon trim. Like many readers, I was skeptical, too. The vehicle only offers 21 miles of electric range before becoming a hybrid, and next to […]

Airbus is developing a testing platform called Advanced Superconducting and Cryogenic Experimental powertraiN Demonstrator (ASCEND) to explore the impact of superconducting materials and cryogenic temperatures on the performance of an aircraft’s electric propulsion systems.
The introduction of superconducting materials can lower electrical resistance, which reduces power loss in conductors. When coupled with liquid hydrogen at cryogenic temperatures (-253° C), electrical systems can be cooled in order to increase the performance of the electric propulsion system.
Airbus will use ASCEND to explore the feasibility of these technologies in order to optimize propulsion architecture for low-emission and zero-emission aircraft. Results are expected to show the potential for component weight and electrical losses to be at least halved, as well as a reduction in voltage to below 500 V.
ASCEND will assess electric architectures from several hundred kilowatts to multi-megawatt applications, with and without liquid hydrogen on board.
Airbus will design and build the demonstrator over the next three years at its E-Aircraft System House. Solutions that could be adapted to turboprop, turbofan and hybrid propeller engines will be tested and evaluated by the end of 2023. The new system will support Airbus’s decision-making process for the type of propulsion system architecture required for future aircraft. ASCEND is also expected to support performance improvements for existing and future propulsion systems across the entire Airbus portfolio, including helicopters and eVTOLs, as well as regional and single-aisle aircraft.
BYD, a major manufacturer of transit buses, is introducing a battery-electric Type D school bus. According to the company, the new e-bus offers “unparalleled safety features and performance, wrapped in a sleek design that will have students wanting to step onboard.”
BYD’s Type D school bus will come in 35-, 38-, and 40-foot lengths, and will offer a range of up to 155 miles. It can seat up to 84, and can be equipped with an ADA-compliant liftgate.
The new e-bus will use BYD’s lithium iron phosphate battery, and BYD’s proprietary powertrain, which features dual in-wheel traction motors.
BYD says its school buses can cut fuel and maintenance costs by as much as 60% compared to diesel vehicles.
School buses offer an ideal use case for bidirectional charging. The ability to feed energy back to the grid during downtime offers an income opportunity that can offset the cost of converting a fleet to EVs. BYD’s new bus follows the current industry trend and offers bidirectional charging.
“We are raising the bar for design, innovation, range and quality, giving parents peace of mind knowing their children are benefitting from the safest school bus anywhere,” said Stella Li, President of BYD North America. “At the same time, our buses will give operators the performance and cost savings that will make migrating to zero-emission technology affordable and practical.”
BYD made safety the top priority in its school bus design, including such features as electronic stability control, a collision avoidance system, and a 360-degree monitoring system to detect pedestrians and cyclists. BYD buses can be equipped with IMMI’S Safeguard 3-point lap-shoulder belts, integrated child seats, and portable restraints.
“We believed the Type D electric bus needed to be appealing to kids while at the same time offer the upmost safety features and driver ergonomics, be equipped with a safe, high-performance battery, and have plenty of storage capacity for road trips,” said Samuel Kang, BYD’s Head of Total Technology Solutions. “The BYD Type D school bus achieves all those goals.”
Contrary to popular belief, EV drivers don’t have to subsist on kale and granola—now you can have a Slurpee and a microwaved burrito while topping up your battery pack. The iconic American convenience store chain 7‑Eleven plans to deploy at least 500 DC fast charging stations at 250 selected stores in the US and Canada by the end of 2022.
The new charging stations will be owned and operated by 7‑Eleven, which already has 22 charging stations located at 14 stores in 4 states.
In 2016, 7‑Eleven planned to achieve a 20% reduction in carbon emissions from its stores by 2027. In the event, this goal was reached in 2019, 8 years early, and the company has now pledged a 50% reduction by 2030. 7‑Eleven is purchasing 100% wind energy for over 800 stores in Texas and over 300 in Illinois. In Virginia, 150 stores are using hydropower, and 300 Florida stores are powered by solar energy.
“7‑Eleven has always been a leader in new ideas and technology,” said 7‑Eleven CEO Joe DePinto. “Adding 500 charging ports at 250 7‑Eleven stores will make EV charging more convenient and help accelerate broader adoption of EVs and alternative fuels. 7‑Eleven’s legacy is bringing convenience to the customer, and that continues to evolve—from ice on a dock in 1927 to electricity for your car today.”
