Electric Buses Using Ultracapacitors Will Be Put To The Test in Washington
A U.S. company and its Chinese partner will test electric buses using ultracapacitors that would be chargeable at stops every few miles. The latest ultracapacitors store only 5 percent of the energy that lithium-ion batteries can hold, making them impractical for passenger vehicles. But proponents say the fact that buses have to stop frequently — and at predictable locations — make them a more logical use of the technology.
