The invention belongs to the technical field of low-voltage power distribution of new energy vehicles, and particularly provides a low-voltage power distribution system of a new energy commercial vehicle, which comprises a main control unit, a mode setting unit, a control unit, a distribution unit, a monitoring unit, an output protection unit and a power supply unit for supplying power to the whole system, flexible configuration of 24V electricity and 12V electricity is achieved through the distribution unit, and the requirement that a commercial vehicle is assembled with a 12V electrical component of a passenger vehicle is met; the output voltage of the mode setting unit and the output voltage of the distribution unit are compared and verified, so that the problem that the actual distribution of the voltage of each path is inconsistent with the target required voltage is avoided; and finally, two information configuration modes including an 8-bit DIP dial switch configuration mode and a two-multiplexer configuration mode are provided, flexible configuration can be performed through the main control unit, and output combination of multi-branch 24V and 12V power supply is realized.

    本发明属于新能源汽车低压配电技术领域,具体提供一种新能源商用车的低压配电系统,包括主控单元、模式设置单元、控制单元、分配单元、监测单元、输出保护单元和为整个系统供电的电源单元;本发明通过分配单元实现24V电和12V电的灵活配置,兼容商用车装配乘用车12V电气部件的需求;并通过对模式设置单元和分配单元的输出电压进行比对校验,避免每路的电压实际分配与目标需求电压不一致的问题;最后,同时具备通过8位DIP拨码开关配置方式和通过两个多路复用器配置方式的两种信息配置方式,通过主控单元可以进行灵活配置,实现多支路24V和12V供电的输出组合。
