The invention discloses a heat management system of a pure electric vehicle. The system comprises a vehicle-mounted air conditioner and a battery management system BMS, and liquid cooling circulation of the battery management system BMS exchanges heat with the vehicle-mounted air conditioner at a heat exchanger of the vehicle-mounted air conditioner; the vehicle-mounted air conditioner comprises an electric compressor EAC and a PTC heater, and the electric compressor EAC and the PTC heater are in communication connection with a vehicle control unit VCU. The vehicle-mounted air conditioner is matched with the liquid cooling system to regulate the temperature of the power battery, so that the temperature regulation capability of the power battery can be greatly improved, and the service life of the power battery can be prolonged; when the non-enabling faults of the heater PTC and the electric compressor EAC are detected, the output power of the heater PTC and the output rotating speed of the electric compressor EAC are limited, and the operation safety of the vehicle-mounted air conditioner is improved.
本发明公开一种纯电动汽车的热量管理系统，所述系统包括：车载空调及电池管理系统BMS，电池管理系统BMS的液冷循环在车载空调的换热器处与车载空调进行热交换；所述车载空调包括电动压缩机EAC和PTC加热器，电动压缩机EAC、PTC加热器与整车控制器VCU通讯连接。通过车载空调配合液冷系统对动力电池进行调温，能极大的提高动力电池的调温能力，有利于延长动力电池的使用寿命；在检测到加热器PTC、电动压缩机EAC存在非使能故障时，限制加热器PTC的输出功率及电动压缩机EAC的输出转速，提高了车载空调的运行安全性。
