High-voltage electrical control system, control optimization method and electric vehicle

The invention provides a high-voltage electrical control system, a control optimization method and an electric vehicle, and the high-voltage electrical control system comprises a first-stage controller and a plurality of second-stage controllers. A first space is formed in the first-stage controller, and the first-stage controller is provided with an air hole communicated with the first space; a ventilation valve is arranged at the ventilation hole; the ventilation valve has a first ventilation volume; and a second space is formed in each secondary controller and is communicated with the first space through an air guide pipeline. The high-voltage electric appliance control system provided by the invention has the advantages of reducing part cost and effectively preventing water flow from entering the controller to cause short circuit of the controller. 本申请提供一种高压电气控制系统、控制优化方法及电动汽车，其中，高压电器控制系统包括：一级控制器和多个二级控制器；一级控制器内部具有第一空间，一级控制器具有与第一空间相连通的透气孔；透气孔处配置有透气阀；透气阀具有第一透气量；每个二级控制器内部均具有第二空间，第二空间通过导气管路与第一空间相连通。本申请提供的高压电器控
