Abstract

The invention provides an energy storage system and a self-heating method. The energy storage system comprises a first unit, a second unit and a control unit, wherein the first unit comprises a first power conversion system and a first battery system, and the second unit comprises a second power conversion system and a second battery system; and the control unit is used for controlling the first power conversion system and the second power conversion system to perform mutual charging, namely performing mutual charging on the first battery system and the second battery system. By mutually charging the first battery system and the second battery system, the first battery system and the second battery system can be heated by utilizing heating of resistors in the battery systems, so that the temperature of the battery systems can be rapidly increased to a temperature interval suitable for battery operation in a low-temperature state, and the low-temperature starting time of the battery systems is greatly shortened. Compared with the mode of heating the battery through an air conditioner or other external heating equipment, the mode of heating the battery system through mutual charging has the advantages of being high in temperature rise rate, high in heat efficiency, energy-saving and the like.

Description

technical field [0001] The present application relates to the field of electric power, in particular, to an energy storage system and a self-heating method. Background technique [0002] Existing power systems are often equipped with energy storage systems, such as battery systems, which are used to buffer electric energy when the power supply of the grid is surplus, and release the cached electric energy to replenish the grid when the power supply of the grid is tense. The performance of the battery system is affected by its temperature. In many scenarios, such as high-altitude areas, three-north areas, or other cold environments, it is necessary to heat the battery system to increase the temperature of the battery system and make the battery run at a suitable temperature. within the specified temperature range to ensure the performance of the battery system. [0003] In the prior art, the battery is often heated by an air conditioner or other external heating equipment, w...
