Electric Vehicle Innovation for the Future

Decarbonization and electrification of transportation relies heavily on power electronics to distribute the proper amount and type of power between EV system components such as batteries, inverters, converters, chargers, and electric machines. Power electronics also determine the exact nature and timing of the current and voltage waveforms to the electric machine.

NREL's research works to decrease EV system costs, reduce component footprints, and improve power electronics and electric machine component and system performance, reliability, and efficiency—the keys to making wide-scale adoption of EVs more feasible.
