随着特种车辆用电设备种类的增多和功率的增大，对车载供配电系统的供电可靠性、智能化、安全性要求越来越高，传统的车载供配电系统已经不能满足当前特种车辆的用电需求。为了提高车载供配电系统的供电可靠性、智能化水平、安全性，文章设计了一种车载智能高压直流供配电系统，可以自动识别车辆状态，根据使用需求，该系统通过智能控制市电电源、高压锂电池组、发电机组和高压配电箱的工作状态，实现多种电源的冗余供电；同时可在线监测发电机组、高压锂电池组、高压配电箱、整流电源等各种供配电设备的运行情况，为特种车辆供配电系统设计提供参考。

With the increase of the types of electrical equipment and the increase of the power of special vehicles, the power supply reliability, intelligence and safety requirements of the on-board power supply and distribution system are getting higher and higher, and the traditional on-board power supply and distribution system can no longer meet the power demand of special vehicles. In order to improve the reliability, intelligence level and safety of the power supply and distribution system of the vehicle-mounted power supply and distribution system, an intelligent power supply and distribution system is designed, which can automatically identify the vehicle status and intelligently control the working state of the mains power supply, high-voltage lithium battery pack, generator set and high-voltage distribution box according to the use requirements, so as to realize the redundant power supply of various power sources. At the same time, the system can monitor the operation of various power supply and distribution equipment such as generator sets, high-voltage lithium battery packs, high-voltage distribution boxes, and rectifier power supplies online. It provides a reference for the design of power supply and distribution systems for special vehicles.
