An energy storage thermal management system control strategy and method

Abstract

The application discloses an energy storage thermal management system control strategy and method, relates to the technical field of lead-carbon battery energy storage systems, and comprises the following steps: S1, data acquisition; S2, data processing; and S3, predictive control. The energy storage thermal management system control strategy and method have the following advantages. First, the temperature control precision is significantly improved. With the aid of multi-point parameter acquisition, a temperature prediction model and a rolling time domain control framework, the cell temperature can be stably controlled in an optimal working interval, the local temperature difference between cells is effectively reduced, and the influence of temperature fluctuation on the battery performance is avoided. Second, the energy consumption is greatly reduced. By dynamically matching the heat dissipation power and the battery heating power, the starting and running parameters of the thermal management system are optimized in combination with the prediction model, invalid running time is reduced, and the energy consumption of components such as pumps and valves is reduced. Third, the overall operation efficiency of the energy storage system is improved, energy loss caused by insufficient or excessive heat dissipation is avoided, and the performance advantages of lead-carbon batteries are fully utilized.
