These PDUs, also known as junction or fuse boxes, are ideal solutions for battery electric vehicle (BEV) applications. The power distribution unit (PDU) delivers power to all critical traction and auxiliary loads, while protecting electronic components and vehicle occupants.

Located between the electrical vehicle powertrain (E-drive) and the vehicle’s auxiliary systems (heating & air conditioning, power steering, etc.), equipped with high-voltage (HV) fuses, the PDU distributes and protects the vehicle’s auxiliary systems against short circuits and over-currents.

Power Distribution Unit (PDU) The Power Distribution Unit enables the connections with all HV Units (loads, supply) in a single location in the vehicle. Outlets can be fused in-line with the vehicle safety analysis. HV Interlock can be also incorporated to monitor connector integrity.

PDU (Power Distribution Unit)高压配电单元，功能是负责新能源车高压系统中的电源分配与管理，为整车提供充放电控制、高压部件上电控制、电路过载短路保护、高压采样、低压控制等功能，保护和监控高压系统的运行。 PDU也能够集成BMS主控、充电OBC模块、DCDC模块、PTC控制模块等功能，与传统PDU相比多了整车功能模块，功能上更加集成化，结构上更复杂，具有水冷或是风冷等散热结构。 PDU配置灵活，可以根据客户要求进行定制开发，能够满足不同客户 …

HV PDU safely, reliably, and efficiently distributes power from a high-voltage battery module to the high-voltage systems of a vehicle. The high-voltage components are electrically connected through the busbar and wiring harness, which creates a high-voltage system for electric and hybrid-electric vehicles.

The CSNV500, CSNV1500 and CSSV1500 Series are automotive-grade current sensors for battery management systems (BMS), battery disconnect units (BDU) and power distribution units (PDU) in electric vehicles.
