A capacitor electric vehicle is a vehicle that uses supercapacitors (also called ultracapacitors) to store electricity.[1]
As of 2010[update][needs update], the best ultracapacitors can only store about 5% of the energy that lithium-ion rechargeable batteries can, limiting them to a couple of miles per charge. This makes them ineffective as a general energy storage medium for passenger vehicles. But ultracapacitors can charge much faster than batteries, so in vehicles such as buses that have to stop frequently at known points where charging facilities can be provided, energy storage based exclusively on ultracapacitors becomes viable.[2]
