Abstract

One or more embodiments of the invention provide a method and a device for determining the health condition of an energy storage device, and a power supply system. The method can comprise the following steps: periodically and alternately performing charging operation for a first time length and standing dormancy for a second time length on a to-be-detected energy storage device; and determining the health condition of the to-be-detected energy storage device, wherein the health condition is related to the voltage data of the to-be-detected energy storage device in the standing sleep stage.

Description

technical field [0001] One or more embodiments of this specification relate to the field of electric power technology, and in particular to a method and device for determining the health status of an energy storage device, and a power supply system. Background technique [0002] Compared with the traditional UPS (Uninterruptible Power Supply, uninterruptible power supply) power supply system, the HVDC (High-Voltage Direct Current) power supply system has the advantages of simple structure, low loss and high efficiency, and is widely used in such as IDC (Internet Data Center, Internet Data Center) computer room, to supply power to electrical equipment such as servers in the computer room. Among them, the HVDC power supply system includes an energy storage device, which can provide short-term power supply for the electrical equipment in the computer room in case of emergency, so as to ensure the uninterrupted operation of the electrical equipment. Certainly, the energy storag...
