Abstract

The invention provides a thermal management method of an energy storage system, a controller and the energy storage system. The method comprises the steps: obtaining battery parameters of a battery system, further determining a temperature adjustment strategy of a temperature adjustment system according to the obtained battery parameters, and triggering the temperature adjustment system to execute the determined temperature adjustment strategy to adjust the temperature of the battery system. The scheme is applied to a system-level controller, the system-level controller and the temperature adjustment system achieve linkage control and coordinated control, the system-level controller determines a temperature adjusting strategy of the temperature adjustment system according to battery parameters of the battery system, then the temperature adjustment system is controlled to execute the temperature adjustment strategy, and finally, the temperature adjustment system adjusts the temperature of the battery system according to the battery parameters, so that the temperature adjusting precision of the battery system is improved.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a heat management method, a controller and an energy storage system of an energy storage system. Background technique [0002] The core part of the energy storage system is the energy storage battery. The performance of a large-capacity, high-power energy storage system varies greatly with temperature. Long-term exposure to high or low temperature environments or system temperature differences will affect the life and performance of the battery. Therefore, for a high-power energy storage system, it is necessary to use a special cooling device (such as a temperature regulation system) to adjust the temperature of the energy storage battery to a suitable temperature. [0003] However, the current energy storage system is usually a temperature regulation system that usually adjusts the flow and temperature of the liquid coolant according to a given temperature, an...
