Hybrid power supply for battery and capacitive tram
Modern five-module energy storage tram project of Zhuzhou Locomotive 

High power lithium titanate battery, and support rate discharge at minus 20 degree centigrade; 

In case of insufficient capacity of battery - capacitor hybrid tram, the battery provides power traction to reduce the number of charging stations; 

Redundant control can be provided: In case of failure of a group of DCDC and batteries, the group of DCDC and batteries are out of operation, and the remaining group of batteries ensure that the vehicle continues to run;  

The battery system has an effective energy storage capacity of 30Wh, and the rated voltage of 750V.
