I've seen them used mostly in buses for short term regen purposes (they can absorb lots of power very quickly from a heavy vehicle stopping, and then release it back out to accelerate back up to speedmore so than a battery pack) Jay On 6/25/20 2:10 PM, Lee Hart via EV wrote: A

In the early 2000s, Solectria (RIP) used supercaps experimentally as current levelers in EVs. They hoped to get more range out of lead batteries. The idea worked, to a degree, but the caps' rapid voltage fall meant they needed a DC:DC converter, and its (in)efficiency was a problem. Also,
