The invention discloses a heat storage type heat pump heat management system and a control method, and belongs to the field of automobile heat management systems. According to the technical scheme, the heat storage type heat pump heat management system comprises an air conditioner refrigerant loop, a power battery cooling liquid loop and a motor cooling circulation loop; the heat of the passenger compartment or the power battery is transferred to the external environment through the outdoor condenser in summer, the compressor is low in energy consumption and high in efficiency during energy transfer, and during charging in winter, the power battery has the characteristics that the required charging current becomes smaller along with the increase of the SOC, and the charging power provided by the charging pile is not changed, so that the charging efficiency is improved. The electric quantity is stored in the cooling liquid, the power battery, the second auxiliary water tank and the motor in the form of heat, the heat is transferred to a passenger compartment in a primary energy transfer mode and a secondary energy transfer mode after charging, the problem that the electric quantity of the power battery is excessively used is avoided, and the driving range of the whole vehicle is increased.
本发明公开了一种蓄热式热泵热管理系统及控制方法,属于汽车热管理系统领域。本发明采用的技术方案为,一种蓄热式热泵热管理系统,包括空调冷媒回路、动力电池冷却液回路以及电机冷却循环回路;本发明在夏季将乘员舱或者动力电池的热量通过室外冷凝器转移至外界环境,能量转移时压缩机的能耗低、效率高,在冬季充电时,利用动力电池具有随着SOC增大需求的充电电流变小、充电桩可提供的充电功率是不变的特性,将电量以热量的形式存储于冷却液、动力电池、第二副水箱及电机中,在充电后再将热量以一级能量转移模式、二级能量转移模式的方式转移至乘员舱,避免过多使用动力电池电量的问题,提高了整车续驶里程。
