Book review—Power Play: Tesla, Elon Musk, and the Bet of the Century
Considering the massive media coverage of Tesla over the last decade, it may seem surprising that there aren’t more books about the company. When I first released my history of Tesla in 2014, I expected to have a short window of exclusivity before a “real” book—one with a hard cover and celebrity blurbs on the… Read more »
GM to deploy 40,000 Ultium-branded Level 2 chargers at community locations
A pair of related announcements from GM indicate that, as the company moves steadily forward with electrification, it understands the critical importance of charging infrastructure. Ultium Chargers GM will introduce its own line of residential and commercial chargers under the Ultium brand.

Why is Hertz deploying a huge fleet of Teslas? Hint: it has little to do with emissions.
Are rental car customers ready for EVs? We’re going to find out. Rental giant Hertz theoretically began introducing EVs to its fleet in 2011, and competitors soon followed. However, they were offered only in select markets, sometimes at super-premium prices. Meanwhile, Teslas became popular on the peer-to-peer rental network Turo. Now Florida-based Hertz, which rents… Read more »
Simplifying Automotive Emergency Power Supply Architecture
In this presentation, we will review the low voltage power architecture used in automotive traction inverters. This power source drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This last requirement represents a special challenge as it means the Emergency Power Supply… Read more »

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 »
