World's Fastest Charging Electric Bus Takes 10 seconds to Charge

The world's fastest charging electric buses, that takes just 10 seconds to be fully charged, were put into operation for the first time in Ningbo on Tuesday.

The bus operates a 11-km route with 24 stops in Ningbo, Zhejiang province, local transport authorities said.

In the next three years, a total of 1,200 such buses will be used for public transport in the city, where the electric bus plant is located.

The bus recharges while stationary or while passengers get on or off, and each charge enables the bus to run for 5 kms, according to Zhou Qinghe, president of Zhuzhou Electric Locomotive, a subsidiary of high-speed train maker CRRC.

The bus converts more than 80% of the braking/potential energy generated during braking and traveling down slopes into electric and store it for recycling, and thus cutting down electric energy consumption by 30%-50% compared to the conventional bus under the same operating conditions.

In 2013 ABB unveiled a similar wireless electric bus with 15 second Flash charging.

Supercapacitor technology has been tested in Shanghai for more than eight years, clocking up more than eight million kilometres. The organic super capacitors - the core component of the bus - are fabricated from high-performance carbon material, can be recharged and discharged repeatedly more than one million times, are adaptable to all environmental conditions (-40~65°C) and have a service life up to 12 years as long as that of the bus itself. The bus has one-tenth the energy cost of a diesel bus with lifetime fuel savings of $200,000.
