The invention discloses a passenger compartment priority refrigeration control method for a pure electric vehicle heat management system. The method is characterized by comprising the following steps:1) entering a simultaneous refrigeration mode, and starting an electric refrigeration system and a battery cooling water loop; 2) entering a passenger compartment priority refrigeration mode, and closing the battery cooling water loop; 3) keeping entering the passenger compartment priority refrigeration mode; 4) quitting the simultaneous refrigeration mode, and restarting the battery cooling water loop; 5) keeping quitting the simultaneous refrigeration mode; and 6) repeatedly circulating step 2) and step 4) until the simultaneous refrigeration mode is quitted. On the premise that the safetyof the power battery is guaranteed, the refrigeration requirement of the passenger compartment is preferentially guaranteed; and the system is frequently switched, so the running stability of the system is guaranteed.
本发明公开了一种纯电动汽车热管理系统乘员舱优先制冷控制方法,其特征在于:包括1)进入同时制冷模式,开启电动制冷系统和电池冷却水回路;2)进入乘员舱优先制冷模式,关闭电池冷却水回路;3)保持进入乘员舱优先制冷模式;4)退出同时制冷模式,重新开启电池冷却水回路;5)保持退出同时制冷模式;6)重复循环步骤2)和步骤4),直到退出同时制冷模式。在保证动力电池安全性的前提下,优先保证乘员舱的制冷需求;系统进行频繁地切换,从而保证了系统运行的稳定性。
