A Japanese multinational conglomerate corporation, TOSHIBA has recently begun field tests on a medium-sized EV bus in Japan, that can perform a charge in just 15 minutes, which the company says is roughly a quarter of the time that similar lithium-ion cells take. It is using a new type of contactless charging method for electric vehicles (EVs).
The 45-seater EV bus, that is powered by a high-output lithium-ion battery manufacturer by Toshiba, will be driven between Tokyo and Kawasaki to assess its suitability for regular high-speed journeys on motorways.
Toshiba’s contactless charger has been designed in collaboration with the Waseda University and replaces conventional electromagnetic induction with a magnetic resonance sys that is installed in the ground beneath the vehicle. The charging starts once the driver pushes a button on the bus dashboard and because the sys is cable-free, it eliminates the risk of electric shock.
According to the Company, the battery housed in its electric bus has been designed to withstand more than 15,000 quick charge and discharge cycles. It also claimed that just fifteen minutes of charge gives the vehicle enough power to travel one way between the test sites, which making it suitable for shuttle buses that operate in places like airports and tourist spots. At the same time, the high-output nature of Toshiba’s SCiB battery allows the bus to reach high enough speeds to make it safe to drive on motorways, the Toshiba said.
The 11km (7 mile) journey between All Nippon Airways facilities in Tonomachi, Haneda Airport and Kawasaki in Tokyo will examine the bus’s performance under different traffic conditions and will enable Toshiba to test the convenience and practicality of contactless charging, the company said. The vehicle will make 3 round trips per day and is powered by the manufacturer’s rechargeable lithium–titanate battery, dubbed Super Charge Ion Battery (SCiB), which can provide up to 89km (55 miles) on a single charge.
Field tests of the electric bus will take place between 1st of June and December 2016.
