The world's fastest charging electric busses, that takes just 10 seconds to be fully charged, were put into operation for the first time in Ningbo on Tuesday.
...
The bus recharges while stationary or while passengers get on or off, and each charge enables the bus to run for least five kilometers, according to Zhou Qinghe, president of Zhuzhou Electric Locomotive, a subsidiary of high-speed train maker CRRC.
In addition, the bus, which rolled off production line in April, consumes 30 to 50 percent less energy than other electric vehicles.
The capacitor can be charged one million times and has a 10-year life cycle. The bus has one-tenth the energy cost of a diesel bus with lifetime fuel savings of $200,000.

(568 posts)Similar to the Volt-- who'd a thunk Chevy would have a breakthrough like that.
Of course it wouldn't have happened under a republican.

(34,589 posts)Capacitors have a tiny energy capacity compared to batteries, but only 5km is claimed per charge, so that might work. But all of that energy in 10 sec? Not easy, particularly to do over many charge cycles.

(29,798 posts)They are also using busses not cars.

if their energy density can be improved sufficiently.

(29,798 posts)The energy stored must ultimately provide a durable power to weight ratio for the entire contraption.
Fm yr article:
Do you happen to know the difference in weight between a loaded bus and a loaded passenger car?

(19,938 posts)Why?
Capacitors, in concept, are better than batteries (for all the reasons listed in the OP) except, currently, batteries can hold more. The relative weights of the vehicles are irrelevant.
