| Zusammenfassung: | The invention provides an energy storage system which is characterized in that when the temperature of at least one battery unit is lower than a preset temperature, an electric energy conversion and transmission path is controlled to be formed between the corresponding battery unit and a current supply device connected to a direct current bus; as certain internal resistance exists in the battery unit, Joule heat can be generated on the internal resistance in the electric energy transmission process between the battery unit and the current supply equipment, and then the purpose of heating the battery unit is achieved; and in the process of heating the battery units through electric energy transmission, heat comes from the interiors of the battery units, so that heating is uniform, and the speed is high. Besides, the electric energy transmission process can be realized by means of a corresponding circuit in the energy storage system without adding any external equipment, so that the problems of high cost, compl |
