System description (battery-swap version)系统说明(换电版)

The high-voltage power distribution box (PDU) of the battery-swap model is a high-voltage power distribution box and a high-voltage power distribution box inside the integrated electric drive assembly.换电版车型高压配电盒(PDU)分别是高压配电盒、集成电力驱动总成内部的高压配电盒。

The high-voltage distribution box contains a DC fast charging relay inside. When the vehicle is fast-charged, the BMS controls the internal DC fast charging relay to close to realize DC fast charging of the vehicle. In addition, high-voltage electricity passes through the high-voltage distribution box to the high-voltage distribution box inside the integrated electric drive assembly.高压配电盒内部包含快充继电器，当对车辆进行快充时，BMS控制内部的快充继电器闭合，实现车辆快速充电；除此之外，高压电通过高压配电盒到集成电力驱动总成内部的高压配电盒。

The high-voltage distribution box inside the integrated electric drive assembly contains a high-voltage fuse. The high-voltage power from the battery pack passing through the high-voltage distribution box is distributed through different high-voltage fuses to the air-conditioning compressor (ECP), high-voltage coolant heater (PTC), motor controller, DCDC, and on-board charger (OBC) (when the vehicle is discharged to the outside).集成电力驱动总成内部的高压配电盒含有高压保险，将经过高压配电盒的电池组箱的高压电通过不同的高压保险分别向空调压缩机(ECP)、高压液体加热器(PTC)、电机控制器、DCDC、车载充电机(OBC)(车对外放电时)分配高压电源。
