Optimizing EV Powertrain Test Instrumentation and Improving Measurement Results
This presentation will demonstrate how test instrumentation of electric vehicle powertrains has been simplified while improving accuracy with innovative new measurement technology from CSM. The challenges associated with instrumenting test benches and electric vehicles are numerous, and are primarily associated with safely measuring current and voltage at many points throughout the high-voltage powertrain—such as between… Read more »
JB Straubel talks Tesla, Redwood and the massive challenge of building an EV supply chain in new video
When I was a kid, everyone had a favorite Beatle (mine was George). Now I have a favorite Tesla co-founder: JB Straubel. He’s a visionary who converted a Porsche to electric drive and built a solar-powered racer, long before EVs were cool. He’s the engineering genius who personally went through and redesigned almost every component… Read more »
Atom Power to provide digital circuit breakers for NYC multi-family EV charging project
Atom Power has come up with a novel way to simplify charging stations, potentially reducing equipment and maintenance costs. Atom’s UL-listed solid-state digital circuit breaker centralizes the power management system—the smart technology that charges the vehicle resides in the electrical panel, and the charging pedestal or wall box does not contain high-tech electronics. Now technology… Read more »
Indian ride-hailing and charging startup BluSmart raises $25 million in Series A funding round
Indian EV ride-hailing and charging company BluSmart has raised $25 million in a Series A funding round led by bp ventures, which invested $13 million. Other investors included Mayfield India Fund, 9Unicorns and Survam Partners. Sophia Nadur, Managing Partner at bp ventures, will join BluSmart’s board.

Simplifying EV traction inverters emergency power supply architecture
The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »
Chevrolet’s electric Silverado pickup to debut at CES 2022
Electric pickups are expected to be the next big thing, and newcomer Rivian stole a march on everyone—Ford’s F-150 Lightning is in pre-production, but deliveries aren’t to start until spring of 2022. Tesla’s Cybertruck is delayed until who-knows-when. GM may be struggling to catch up, but it’s moving forward. The latest news is that Chevrolet’s… Read more »
Road test indicates existing electric trucks could replace millions of diesels on short-haul routes
When it comes to long-haul trucking, battery-electric trucks face a number of challenges, including weight restrictions and the need for an ultra-high-power charging solution. However, despite what you may read in those “anything but EVs” articles, the jury’s still out on when, or whether, battery and charging specs will improve to meet these challenges, or… Read more »
Lyten introduces lithium-sulfur battery platform
Material supplier Lyten has introduced its new LytCell lithium-sulfur (Li-S) battery platform. The new platform was developed specifically for the EV market, and is designed to deliver three times the specific energy of lithium-ion batteries. Lyten has previously worked with the US government to test LytCell in defense-related applications, and is now ready to introduce… Read more »
Volkswagen’s ID.4 electric crossover has it all—practical and fun
The Volkswagen ID.4, which went on sale in the US earlier this year, could turn out to be a very important vehicle for a couple of reasons. It’s the first of VW’s new-generation EVs to reach the US. That is, it’s the first to be built by the post-scandal, reformed and repentant VW, and the… Read more »
