The application belongs to the technical field of electrochemistry, and particularly discloses a wind-cooled electrochemical energy storage cabin temperature control method and system. The scheme takes the temperature corresponding to each battery pack collected by the BMS battery management module as basic temperature data, generates a virtual temperature through dynamic weighting algorithm fusion of all battery pack temperature data, and finally converts the virtual temperature into a corresponding target voltage signal based on the NTC voltage division characteristic. The target voltage signal is used to simulate the NTC voltage division signal and directly input into the air conditioner controller for temperature regulation. That is, on the one hand, the scheme realizes effective utilization of the temperature data collected by the original BMS battery management module of the energy storage cabin, reduces the number of NTC temperature sensors arranged in the cabin body, and can more accurately and comprehensively reflect the temperature in the cabin. On the other hand, based on the NTC voltage division characteristic, the virtual temperature is converted into a corresponding target voltage signal to simulate the original NTC voltage division signal, without the need to modify the air conditioner hardware and program, and the scheme is compatible with existing various wind-cooled air conditioner systems based on NTC sampling.
