Abstract

The invention discloses a whole storage battery pack as well as a maintaining device and method thereof. The storage battery maintaining device is connected with storage batteries in the whole storage battery pack to be maintained in parallel; a voltage acquisition circuit in the maintaining device is used for acquiring voltage values at two ends of each storage battery; a driving circuit is used for comparing the acquired voltage values with a preset voltage threshold; when the acquired voltage values are higher than the preset voltage threshold, a constant current circuit is driven to work; when the acquired voltage values are lower than the preset voltage threshold, the constant current circuit is controlled to withdraw, that is, an external power supply is adopted to apply voltage to the present storage battery till the voltage of the present storage battery is normal. In the whole process, the voltage balance degree of the whole storage battery pack is improved, the influence of over-charge or insufficient charge to the performance (or the service life) of a single battery is avoided, and meanwhile, the improvement on the capacity of the storage battery pack is achieved. The whole storage battery pack is high in working efficiency and excellent in performance.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a whole set of accumulators, a maintenance device and a maintenance method thereof. Background technique [0002] The DC power supply system in the electric power system is composed of a charging device, a battery, a feed-out circuit, a voltage regulating device and related control, measurement, signal, protection, adjustment units and other equipment. It is a control, signal, relay protection, automatic device and It is an important part of the safe operation of the power system to provide reliable working power for accident lighting. The reliability and safety of the DC system itself directly affects the safety of the entire power system. With the continuous increase of the operation time of the DC system of the substation, the problems exposed in the DC system are not uncommon. The most prominent problem is that many batteries in the long-term operation battery pack will ...
