The invention relates to the technical field of vehicle control, in particular to an energy distribution control method for a high-voltage device of a pure electric vehicle. Comprising the steps that the states of a vehicle are divided, and when the vehicle is in a non-high-voltage output state, all high-voltage devices are not allowed to work; when the vehicle is in an alternating current charging preheating state, the priority of energy use is the DC/DC converter gt; when the vehicle is in an alternating-current charging high-voltage state, the priority of energy use is a DC/DC converter gt; a battery heater > a passenger compartment heater gt; when the vehicle is in a direct current charging preheating state, the priority of energy use is a DC/DC converter gt; a passenger compartment heater gt; a compressor gt; when the vehicle is in a direct-current charging high-voltage state, the priority of energy use is a DC/DC converter gt; a passenger compartment heater gt; a compressor gt; a battery heater. According to the method, the comfortable use requirement of the passenger compartment and the safe and reliable working requirement of the battery are balanced, and the driving range of the pure electric vehicle is increased.

    本发明涉及车辆控制技术领域,具体涉及一种纯电动车辆高压器件能量分配控制方法。包括对车辆的状态进行划分,当车辆处于非高压输出状态时,各个高压器件不允许工作;当车辆处于交流充电预加热状态时,能量使用的优先级为DC/DC转换器>电池加热器,当车辆处于交流充电高压状态时,能量使用的优先级为DC/DC转换器>电池加热器>乘员舱加热器>压缩机,当车辆处于直流充电预加热状态时,能量使用的优先级为DC/DC转换器>乘员舱加热器>压缩机>电池加热器,当车辆处于直流充电高压状态时,能量使用的优先级为DC/DC转换器>乘员舱加热器>压缩机>电池加热器。本方法均衡了乘员舱舒适使用需求和电池安全可靠工作需求,提升了纯电动车续驶里程。
