Abstract

The invention provides an on-line storage battery capacity testing system and method in a high-voltage direct current and mains supply direct supply mode, and relates to the technical field of storagebattery capacity test technologies. The system comprises: a storage battery pack powered by a high-voltage direct current power supply system; a rectifier which is used for providing charging voltagefor the storage battery; a rectifier control unit which is used for controlling the rectifier module to adjust the output voltage; a data acquisition and monitoring unit which is used for monitoringthe state of the storage battery in real time and acquiring data information of the storage battery pack during a discharge test; and a data analysis and processing unit which is used for processing and analyzing the data information of the storage battery acquired by the data acquisition and monitoring unit. According to the invention, the problem of an online storage battery capacity test in a high-voltage direct current and commercial power direct supply mode is solved: a storage battery online discharge test is adopted in a data center high-voltage direct current and commercial power direct supply mode, the defects of an offline test in a traditional storage battery capacity test are avoided, and the operation safety and convenience are improved.

Description

technical field [0001] The invention relates to a storage battery capacity testing technology, in particular to an online storage battery capacity testing system and method under the mode of high-voltage direct current and mains direct supply. Background technique [0002] 240VDC (high voltage direct current, HVDC) power supply system is one of the mainstream power supply systems for communication equipment rooms and data centers. For dual-power load equipment, the conventional DC system power supply method is generally a single-system dual-circuit power supply, while the 240V DC system also supports the "high-voltage DC + mains direct supply" mode, which further improves availability and saves energy consumption. However, in this mode, the battery pack of the power supply system cannot perform the online capacity test in the conventional way, and it needs to be researched and solved to find an innovative method to improve the timeliness, accuracy and convenience of battery ...
