Discharge test device for distributed full online storage battery pack

Abstract

The invention provides a discharge test device for a distributed full online storage battery pack, which comprises a DC-DC host machine work power supply, a control unit, a storage battery pack online test switch, a second safety protection circuit, a storage battery pack online test switch control circuit, a safety protection circuit, an automatic current-limiting charge and equipotential connection safety control circuit, a DC-DC converter, a constant current discharge load intelligent control circuit and a discharge load circuit, wherein the safety protection circuit, the automatic current-limiting charge and equipotential connection safety control circuit are mutually connected in parallel, and the constant current discharge load intelligent control circuit and the discharge load circuit are connected in series. The invention can be used as a group or more groups or storage battery packs to carry out discharge maintenance test one by one, thereby the function of online storage battery pack to discharge the communication device load safely with energy conservation and assist the constant current discharge load intelligent control circuit to adjust the discharge load current isrealized, and the invention has the advantages of intelligence, simple operation, safety and energy conservation.

Description

【Technical field】 [0001] The invention relates to power supply maintenance equipment in a communication network, in particular to a distributed all-on-line storage battery pack discharge test equipment. 【Background technique】 [0002] The existing wireless base station power backup battery maintenance and management in the communication industry, due to the large number of wireless base stations, high maintenance labor intensity, high cost, high risk, heavy maintenance tasks, and waste of energy, most of the battery capacity discharge test The maintenance work has not been implemented in place, resulting in the ignorance of the actual capacity of the backup battery pack of the wireless communication base station, the duration of emergency power supply is not clear, and the emergency power generation dispatch management cannot be effectively carried out due to the interruption of the mains power supply, which often leads to communication interruption accidents of the wireless ...
