We could have electric buses that recharge in 15 seconds
Switzerland's Ecole Polytechnique Federale de Lausanne (EPFL) is leading of a group of public and private entities that is developing something called the TOSA bus system. TOSA buses get recharged via a robotic arm that connects the roof-mounted bus batteries to an electric charging system mounted on the bus stop. The buses can hold up to 133 people and the "flash charging" provides enough juice in a 15-second charge to get the bus to the next electrified stop without delaying the route. The researchers say such buses could be put into regular service in Geneva by 2017.
Bus electrification has been topical because of the traditionally low fuel economy of diesel-powered municipal buses as well as the troublesome electrification systems that require overhead lines for electric power. With that in mind, companies like China-based BYD have been developing battery-electric buses. This spring, BYD started making electric buses at its California factory and, earlier in the year, said it received an order for 1,200 electric buses from Dalian, China. There's a 100-second video about the TOSA system below.
