| Abstract: | The braking efficiency of BEV is not as good as conventional cars presently, so magnetic SBAS is re- searched. Based on the brake torque of BEV,a kind of Magnetic SBAS is designed. Using magnetic principle of opposite poles attracting and like poles repelling, magnetic forces help to start and brake BEV,varying with the adjustment of magnetic poles controlled with rear-wheel＇s speed. The magnetic starting and brake torque are calculated. The control circuit of magnetic system is designed. An allocation algorithm of brake force is designed based on ECE. Theoretical computation shows SBAS can help to start and brake BEV quickly and effectively, with efficient dynamic responsive tacho-generator＇s feedback control. A new solution is offered for improving the performance of BEV. |
