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.
