Mainstream consumer adoption of electric vehicles remains stunted by lingering concerns over EV range limitations

There are two major disruptions currently affecting the future of vehicular transport and semiconductor technology. We are embracing a new and exciting means to propel our vehicles cleanly with electrical power, while simultaneously re-engineering the semiconductor materials that underpin electric vehicle (EV) subsystems to maximize power efficiency and, in turn, EV driving range. Larger EV battery sizes that could extend EV range and neutralize consumers’ range anxiety threaten to simultaneously increase EV prices — the battery accounts for more than 25% of the final vehicle cost.

Fortunately, the semiconductor revolution occurring in parallel has yielded new wide bandgap devices such as silicon carbide (SiC) MOSFET power switches that can help shrink the gap between consumers’ EV range expectations and OEMs’ability to satisfy them at competitive cost structures…
