Toyota and Denso have collaborated to develop a silicon carbide (SiC) power semiconductor for use in power control units (PCUs). Using SiC power semiconductors, Toyota aims to improve hybrid fuel efficiency by 10 percent and reduce PCU size by 80 percent, compared to current PCUs with silicon-only semiconductors. The PCU is a critical component of… Read more »

OLEV Technologies’ dynamic wireless inductive system charges vehicles while in motion
When one thinks of Nikola Tesla and electric vehicles, the obvious connection points to Elon Musk’s favorite part-time project. However, we also have to give the Serbian inventor proper credit for pioneering technology that eventually may become even more important to EVs than battery breakthroughs. Tesla’s obsession with wireless power transmission defined much of his… Read more »
