The supercapacitor electric bus is adopted in China

Written by SupercapTech - - 3 comments

China takes the lead in adopting the all-electric bus equipped with supercapacitors.

The Chinese company Sunwin, a joint venture between Volvo and China's largest automaker SAIC had already made a big publicity stunt in 2010 by providing 61 electric buses using supercapacitors to serve the World Expo 2010 of Shanghai.

Buses with supercapacitors of Sunwin brought in their 2010 version an autonomy from 3 to 6 km. Supercapacitors are then charged on each bus stop with a pantograph (like a tram). 30 seconds are enough to charge the bus to 50% and it takes 80 seconds to charge to 100%.

Here is a video where we see the supercapacitor bus to recharge in a bus stop:

World's fastest charging electric bus : 10 seconds thanks to supercapacitors

Written by SupercapTech - - 6 comments

A new electric bus was put into operation on July 28th, 2015 in China. Its special feature: a full charge in just 10 seconds thanks to its supercapacitors.

This bus travels a line of 11 km with 24 stops in Ningbo city on the East coast of China. In the next three years, no less than 1,200 of these buses will be used for public transport in the city, where the electric bus plant is located.

This bus is recharged at stop stations, while passengers getting on or off the bus. Each charge allows the bus to travel up to five kilometers.

In addition, the bus consumes 30 to 50 percent less energy than other electric vehicles.

Graphene Supercapacitors 2.8V 30000F and 3V 12000F made in China

Written by SupercapTech - - 5 comments

The Chinese company "Ningbo CSR New Energy Technology", a subsidiary of CSR Zhuzhou Electric Locomotive (the largest train manufacturer in the world) developed graphene supercapacitors with high capacitance.

These new supercapacitors are intended to improve the efficiency of electric buses, trolleybuses and trams with fast recharge and to increase their autonomy.

Thus, a supercapacitor trolleybus should be able to travel 10 km after a charge of one minute, against 6 km for a charge of 30 seconds with the supercapacitor trolleybuses currently operated by the company. The goal is to reduce the number of intermediate charge to better adapt to the requirements of planning and urban construction.
