The invention provides a power regulation and control method for power battery thermal management equipment, which comprises a thermal management system, and the input of the thermal management system comprises the target working temperature of the battery management system and the temperature sensing temperature actually acquired by a battery pack. Refrigeration and heating of the thermal management system are judged according to the difference value S between the temperature sensing temperature actually collected by the battery pack and the target working temperature of the battery management system, and then a thermal management equipment power control signal in a percentage form is output. According to the power regulation and control method of the power battery thermal management equipment, the stability of the temperature regulation and control change rate of the battery thermal management system is improved, the damage degree of too fast temperature rise or temperature drop to the performance and the service life of the battery is greatly reduced, and the power consumption of the thermal management system is obviously reduced.
本发明提供一种动力电池热管理设备功率调控方法,包括热管理系统,所述热管理系统的输入包括电池管理系统目标工作温度和电池包实际采集的温感温度,通过所述电池包实际采集的温感温度和所述电池管理系统目标工作温度的差值S来判定热管理系统的制冷制热,进而输出为百分比形式的热管理设备功率控制信号。本发明的动力电池热管理设备功率调控方法,提高了电池热管理系统温度调控变化速率的稳定性,大大降低了过快升温或降温对电池性能和寿命的损害程度,明显降低了热管理系统功耗。
