Investigation of Determining of Regenerative Braking Torque Based on Associated Efficiency Optimization of Electric Motor and Power Battery Using GA
Regenerative braking is an important means for realizing energy saving and emission reduction of hybrid electric vehicles, the given value of motors regenerative braking torque influences the energy recovery effect. Based on the Besturn HEV (Hybrid Electric Vehicle), a mathematic model of associated efficiency electric motor and battery according to the performance test of the permanent magnet synchronous motor and nickel-hydrogen power battery was set up in this paper, and the value of regenerative torque was determined through the optimization of the mathematic model using GA (Genetic Algorithm). The simulation results show that the method of determination of regenerative torque put forward in this paper is feasible, the motor and battery can achieve efficient operation in the process of regenerative braking and the recovery of braking energy can be improved obviously.
