Supercapacitor is not a battery: charging is ultra fast
Supercapacitors are used as ultrafast batteries with very long life. Ideal storage system for renewable energy and electric transportation, supercapacitors are taking gradually their place alongside or instead of batteries...
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.
The Chinese company Ningbo CSR New Energy Technology has delivered to its parent company CSR Zhuzhou Electric Locomotive its first batch of 5000 supercapacitors 7500 Farads. This is the largest mass production in the world of supercapacitors with such capacitance.
The most advanced countries in the field of supercapacitors are South Korea, the United States, Japan and China. Today there are more than a dozen manufacturers worldwide able to supply large quantities of supercapacitors.
