What We Learned About EV Range Anxiety

On February 28, 2020 in All, Automotive, Connectors, General, Motor Control, Power by Tommy Cummings

We just endured the biggest adventure of our Tesla commitment ... a long-distance journey, an 853km (530-mile) roundtrip in an EV equipped with a 50kW battery that has a 362km (225-mile) range between full charges. We learned valuable lessons, and we’re hopeful for progress.

How Utilities Are Preparing for EVSE

On March 28, 2019 in All, Automotive, Power by David Talbott

Analysts estimate that if every car and light truck on US roads today were an EV, the amount of power they would consume would equal the US’s entire power-generation capacity. What are utility companies doing to support EV charging needs?

SiC Devices Usurp Si MOSFETs and Diodes in Servers, Motors, EVs

On October 1, 2018 in All, Power, Wide Bandgap by Bill Schweber

Switching devices—both transistors and diodes—based on silicon-on-carbide (SiC) are redefining capabilities of power-related circuits. These offer far better efficiency and range than today’s best silicon-only MOSFETs, IGBTs, and diodes, and are already in widespread use in top-tier data centers and server farms.

Lithium, Cobalt, and Lithium-Cobalt Prices, Demand Drive EVs

On March 21, 2018 in All, Automotive, Power by Steven Keeping

The price of Lithium has tripled since 2016 as electric vehicle batteries compete with mobile consumer electronics for the material. But the escalating price, driven by a threat of shortage of supply, is unlikely to dampen EV demand. Cobalt, another vital ingredient of Li-ion batteries, is another matter, and researchers are working hard to find cheaper alternatives, including Lithium-cobalt.

Batteries: Capacity, Cell Impedance, and Power Fading

On March 7, 2017 in Power by Lynnette Reese

There’s a general expectation these days that a car, even an electric vehicle should operate for 10 to 30 years. Rechargeable batteries are critical for electric vehicles; therefore, it is ideal if the battery can experience numerous and repetitive charge and discharge cycles over years. However, long-term storage capacity is a challenging issue.
