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 ...
