Abstract: In view of the significant decline in the driving range of battery electric vehicle during heating in winter, a new method for efficient utilization of braking energy is proposed. A new type of eddy-current retarding & heating system for electric bus is designed. Through the studies on the braking stability of electro-mechanic-magnetic integrated braking system and the mechanism of eddy-current retarding and heating, the braking control strategy for the system is established, and the simulation and bench test are conducted on the system. The study provides a new idea for enhancing the driving range and safety of electric bus.

Key words: electric bus, efficient utilization of braking energy, eddy-current retarding and heating, integrated braking
