| description | The invention discloses an electric vehicle battery charging temperature control method, system and device and a storage medium. The method comprises the steps that the water inlet target temperature of a target battery pack is determined; the water inlet actual temperature of the target battery pack is obtained, and the basic heating/cooling power is determined according to the water inlet target temperature and the water inlet actual temperature; according to the current charging current and the current battery electric quantity, predicting to obtain a predicted heating value of the target battery pack in the next time period, and determining a first heating/refrigeration compensation coefficient; the historical heating value of the target battery pack in the last time period is determined according to the historical charging current, and a second heating/refrigerating compensation coefficient is determined; and determining first heating/refrigerating power according to the basic heating/refrigerating power |
