The invention relates to the technical field of automobile battery management, in particular to a battery temperature control method and device, a storage medium and a BMS battery system. A PID closed-loop control algorithm is adopted to control the temperature of the battery, and the PID closed-loop control algorithm can adjust the temperature of the cooling liquid in real time according to feedback temperature information of the output cooling liquid; parameters output by the PID are continuously changed, and compared with a traditional method for adjusting the temperature of the cooling liquid in a table look-up mode, the characteristic that the working power of a heat management controller and a water pump is continuously changed can be fully utilized, and energy is better saved; meanwhile, huge workload for manufacturing a control demand matrix table of the thermal management system is saved; in addition, different initialized PID control parameters can be provided according to the possible environment of the battery during actual operation of the electric vehicle, and the control efficiency and effect are improved.

    本发明涉及汽车电池管理技术领域,特别涉及一种电池温度控制方法、装置、存储介质及BMS电池系统。它采用PID闭环控制算法控制电池温度,PID闭环控制算法可以根据输出冷却液的反馈温度信息,实时调节冷却液的温度;PID输出的参数都是连续变化的,相较于传统的查表式调节冷却液温度,可以充分利用热管理控制器和水泵工作功率连续变化的特性,更好的节约能源;同时,节省了制作热管理系统控制需求矩阵表的巨大工作量;本发明还可以根据电动汽车在实际运行时电池可能所处的环境,分别提供不同的初始化PID控制参数,提高了控制效率和效果。
