摘　　要：本系统为采用三路电池同时或者单独给九绕组电机供电的电动汽车动力系统,在主控制单元TSM2812的控制下并行工作,从而保证输出的三组电压同步,当某组蓄电池出现故障时,系统可以自动检测到其故障原因,通过主控单元封锁逆变器驱动脉冲使相应的逆变器停止工作,保证各组电池组独立,减弱了电池的成组效应,提高系统可靠性,保障行车安全;同时,该系统有效避免蓄电池放电时间过长,影响蓄电池使用寿命。为新能源纯电动汽车的推广提供了一种全新的控制理念和技术保障。This system uses 3 battery at the same time or separately supply power to the electric vehicle power system with 9 winding motor. It works in parallel on the control of the main control Unit TSM2812, so as to ensure the synchronization of 3 groups of voltage output. When a group of battery is failure, the system can automatically detect the fault reason, make the corresponding inverter driving pulse stop work by the main control unit of inverter to ensure each battery independent, weakening the group effect of cell, improving system reliability, ensuring the driving safety. At the same time, the system can effectively avoid excessive discharge battery, prolong the service life of battery, it provides a new control concept and technical guarantee for the promotion of new energy of pure electric vehicles.
