The invention relates to the technical field of new energy automobile power supply, and in particular relates to a new energy automobile power supply system which comprises a DC/DC voltage conversionmodule, a battery power supply system monitoring module, a power supply power consumption module, a bus communication module and a high-voltage power distribution module. After the new energy automobile power supply system adopts a hybrid electric automobile and the electric automobile adopts a DC/DC converter, an alternating-current generator can be omitted. The power battery capacity of the electric automobile is very large, so that a power battery is used as a power supply, the DC/DC converter can be used for charging a low-voltage storage battery, and an original alternating-current generator can be omitted. The power distribution scheme, layout, grounding loop and the like of the new energy automobile power supply system supply power to a load well, high voltage adjustment precision and low noise are achieved, and the problems of interference, oscillation, overload and the like among circuits in the system are avoided.

    本发明涉及新能源汽车供电技术领域,具体为一种新能源汽车供电系统,包括DC/DC电压转换模块、电池供电系统监控模块、供电耗电模块、总线通讯模块、高压配电模块。该新能源汽车供电系统采用混合动力汽车及电动汽车采用DC/DC转换器之后,可省去交流发电机。电动汽车的动力电池容量很大,因此以动力电池为电源,能够利用DC/DC转换器为低压蓄电池充电,从而可以省去原来的交流发电机。该新能源汽车供电系统的配电方案、布局、搭铁回路等,对负载良好的供电,达到高电压调整精度、低噪声,避免系统中电路之间的干扰、振荡以及过载等问题的出现。
