Ultracapacitor Buses run on quick charge Batteries

October 20th, 2009 | No Comments | Posted in Batteries

In Shanghai 17 municipal buses runs entirely on ultracapacitor batteries that are charged up during their route at designated bus stops. Without recharging the buses could only go 3 to 5 miles, but the ultracapacitors allow them to charge rapidly. Even if the batteries are completely empty the bus has to stop only for a couple of minutes.

The test project in Shanghai has proven the concept during the last 3 years.

The buses recharge with energy from braking or optionally from solar panels and use 40 percent less electricity compared to other electric trolley buses. Compared to conventional buses with fuel engines, over the vehicle’s 12-year life, Sinautec estimates its buses have one-tenth the energy cost of a diesel bus which would result in lifetime fuel savings of about $200,000.
