Document Type and Number:
WIPO Patent Application WO/2023/221019
Kind Code:
A1
Abstract:
Embodiments of the present application provide a detection method, which is applied to an energy storage system. The energy storage system comprises a control unit and a plurality of energy storage units, and the detection method is executed by the control unit. The method comprises: controlling a first energy storage unit of the plurality of energy storage units to discharge to a second energy storage unit of the plurality of energy storage units within a first preset time period; controlling the second energy storage unit to receive, within the first preset time period, electric quantity discharged by the first energy storage unit; obtaining first voltage information and first current information of the first energy storage unit, wherein the first voltage information comprises a voltage difference of an output end of the first energy storage unit before and after discharging, and the first current information comprises a current flowing through the first energy storage unit in a discharging process; and determining a connection state of the first energy storage unit according to the first voltage information and the first current information. According to the technical solution of the present application, the stability of a power grid can be maintained while the performance of the energy storage system is ensured.
