A pure electric driving system of a large-tonnage mining dump truck comprises a main power supply system with high voltage, a driving motor controller, a driving motor, an auxiliary power supply system with low voltage, an auxiliary system motor controller, load equipment and a bidirectional DC/DC (direct current/direct current), and the main power supply system is connected with the auxiliary power supply system through the bidirectional DC/DC. The main power supply system and the auxiliary power supply system can rescue each other, so that the problem that a vehicle cannot run and needs to be trailed or rescued when a single battery system fails is solved; a main power supply and auxiliary power supply separation mode is adopted, use of high-voltage batteries can be reduced, and cost input of the whole vehicle is reduced.

    一种大吨位矿用自卸车纯电动驱动系统,包括带高压的主电源系统、驱动电机控制器、驱动电机、带低压的辅助电源系统、辅助系统电机控制器、负载设备和双向DC/DC,所述主电源系统与辅助电源系统通过双向DC/DC连接。主、辅电源系统可以互救援,避免了单一电池系统出故障时车辆无法行驶需要拖车或者救援的问题;采用主辅电源分离的方式,可以减少高压电池的使用,降低整车成本投入。
