Electrify America begins building a nationwide network of metro, highway, workplace and community chargers

The two-billion-dollar 10-year investment represents the largest of its kind so far. In the chaos that is human affairs, bad intentions sometimes eventually lead to good results. As atonement for Volkswagen’s criminal actions in what we like to call the Dirty Diesel Debacle, government regulators have forced the automaker to invest substantial resources in promoting… Read more »

Wolfspeed Technology introduces third-gen 1,200 V SiC MOSFET

Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »
