Energy storage battery partition temperature control method, system, device and storage medium

Abstract

The application provides a kind of energy storage battery zoning temperature control method, system, equipment and storage medium, wherein, the method comprises: according to battery pack heat distribution law, the energy storage battery to be controlled is divided into each functional area;Surface temperature of each functional area is collected, current parameter is obtained when the energy storage battery is charged and discharged through current collection unit, and operating condition is determined according to current parameter;According to the surface temperature of each functional area, the threshold value rule is combined to judge the temperature control trigger strategy, and the temperature control trigger strategy is executed under the condition that the operating condition meets the corresponding applicable condition;After a preset delay time at the end of each round of temperature control, the surface temperature is collected again, and the error correction strategy is executed.The application solves the technical problems of uneven overall temperature control, high invalid energy consumption and response lag of existing battery thermal management, has the advantages of high temperature control precision and low energy consumption, can effectively prolong the cycle life of battery pack, and improve the operation safety of energy storage system.
