Charge and discharge test equipment for full on-line storage battery pack

Abstract

The invention provides a charge and discharge test equipment for a full on-line storage battery pack, which comprises a DC-DC host operating power supply, a control unit, a positive and negative polarity change-over switch, a second safeguard circuit, a safeguard circuit, an automatic current limiting charge and equipotential bonding safety control circuit, a DC-DC transducer, a constant current discharge load intelligent control circuit and a discharge load circuit, wherein the safeguard circuit, the automatic current limiting charge and equipotential bonding safety control circuit and the DC-DC transducer are mutually connected in parallel; and the constant current discharge load intelligent control circuit and the discharge load circuit are mutually connected in series. The equipment realizes the best safe operation mode and is suitable for charge and discharge maintenance tests of the on-line storage battery packs of different positive and negative communication power supplies. Nomatter the operating power supply is positively grounded or negatively grounded, when the equipment carries out on-line maintenance test, only the power supply operating grounding terminal connected with side of the storage battery pack needs to be operated, thereby avoiding the risk of short circuit caused by contacting the ground in operation, and the equipment has the charge and discharge maintenance functions of constant current voltage limiting and voltage stabilized current limiting for the on-line storage battery packs, and is more flexible, safer and simpler in use of maintenance test.

Description

【Technical field】 [0001] The invention relates to power supply maintenance equipment in a communication network, in particular to an all-on-line charging and discharging test equipment for battery packs. 【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...
