Problems solved by technology

In practice, if a cell reaches the maximum or minimum voltage before other batteries, the cell will be forced to be deeply discharged or overcharged. After a certain number of times, the cell may be permanently damaged. This invention does not propose a consistent charge-discharge balance On-off switching requirements under optimized conditions

Abstract

The invention discloses a method and device for performing redundant reassembling on storage batteries. The device comprises a storage battery pack, a performance monitoring processing module and a storage battery assembling output module, wherein a plurality of storage batteries are arranged in the storage battery pack; each storage battery is connected with the performance monitoring processing module; the storage battery assembling output module comprises a plurality of on-off selection modules; the storage batteries form a series-connection loop for supplying power to electricity utilization equipment through the on-off selection modules; the quantity of the on-off selection modules is equal to that of the storage batteries, and the on-off selection modules are in one-to-one correspondence with the storage batteries. The performance problem of the storage battery pack during running can be found immediately by the performance monitoring processing module or whether the storage battery pack is in an optimal assembling state can be judged; then the working storage battery with abnormal performance or in a non-optimal assembling state is replaced by the redundant storage battery so as to reassemble a new storage battery pack to keep the normal power supply capacity or improve the power supply capacity.

Description

technical field [0001] The invention relates to the field of storage battery management, in particular to a method and device for a storage battery redundancy reconfiguration group. Background technique [0002] The battery is the main component of the communication network power supply system, providing the final power supply guarantee for the uninterrupted operation of the equipment. Generally, a plurality of storage battery units (referred to as monomers) are made into battery packs to work, and its quantity and capacity are determined by power supply requirements. Taking mobile communication base stations as an example, most of them use valve-regulated lead-acid batteries, and the voltage of the single cell is generally 2V. The power supply voltage and power supply capacity of -48V are provided by using multiple cells connected in series; figure 1 It is a schematic diagram of the power supply system (DC part) of the base station. When the AC power is temporarily interru...
