Abstract

The invention provides a wide-capacity-range battery charging and repairing integrated device. The integrated device comprises an integrated module, a storage battery, a DC / DC module and a rectification module, wherein the output of the integrated module is connected with the storage battery to control charging, discharging and repairing of the storage battery, and the integrated module comprisesa first bridge arm, a second bridge arm and a third bridge arm. The three bridge arms are connected to the positive and negative end of the direct-current bus, namely, the PN end; and the first bridgearm and the second bridge arm can be connected in series and output to the storage battery, and the first bridge arm and the second bridge arm can also be connected in parallel and output to the storage battery. According to the invention, the adaptive capacity range of the storage battery is wider, the charging, discharging and repairing functions can be completed, and the storage batteries of different types, different batches, different models and different aging states can be repaired more flexibly, so that the repairing effect is improved; and the amplitude, the frequency, the positive polarity and the negative polarity of the applied pulse current can be randomly controlled, and the flexibility of repair control is improved.

Description

technical field

[0001] The invention relates to a circuit device for charging or controlling a battery pack in an electric energy storage system, in particular to an integrated converter and control device for charging and discharging batteries and repairing them. Background technique

[0002] In recent years, despite the emergence of various new batteries, lead-acid batteries are still widely used due to their low price, high reliability, and safety. However, due to improper use and maintenance, problems such as plate corrosion and sulfation of the battery will be caused, which greatly shortens the service life of the battery and increases the cost of use. At present, there are many repair methods for this problem. Among them, the characteristics of the battery can be effectively improved and the service life of the battery can be improved by adding an active repair agent and using the pulse repair method. At present, there are many technologies for repairing batteries, bu...
