The invention discloses a low-voltage motor controller of a new energy automobile, and relates to the technical field of automobile parts. Comprising a controller body, and the controller body comprises an aluminum substrate and a first waterproof shell arranged on the top of the aluminum substrate. The same main power board and the same control board can be compatible with two different battery schemes, the difference between the two schemes is that auxiliary source input voltage is different, the auxiliary source input voltage is the same as bus voltage for a vehicle model only equipped with a group of power batteries, the auxiliary source input voltage can be 72V or other input voltage at the moment, and the auxiliary source input voltage and the bus voltage are different. For a vehicle type provided with a storage battery and a power battery at the same time, the input voltage of the auxiliary source is 12V or 24V, and at the moment, only the driving plate needs to be replaced to meet the requirement. According to the design, the material cost is effectively reduced, switching between the waterproof grade IP65 and the waterproof grade IP67 is achieved by replacing the input waterproof shell I and the waterproof shell II, the mold opening cost of structural parts is reduced, and the use requirements of users are met.

    本发明公开了一种新能源汽车低压电机控制器,涉及汽车零部件技术领域。包括控制器主体,控制器主体包括铝基板以及设置于铝基板顶部的防水外壳一。使同一块主功率板和控制板能够兼容两种不同的电池方案,这两种方案的区别在于辅源输入电压不同,对于只配备一组动力电池的车型,辅源输入电压与母线电压相同,此时辅源输入电压可以是72V也可以是其他输入电压,对于同时配备蓄电池和动力电池的车型,辅源输入电压为12V或者24V,此时仅需更换驱动板以满足需求。这种设计有效降低了物料成本,并且通过更换输入防水外壳一和防水外壳二实现防水等级IP65级和IP67级之间的切换,减少了结构件的开模成本,满足用户使用需求。
