Problems solved by technology

[0002] In most DC power supply systems, batteries connected in series are used as an important emergency backup power supply. When the main power supply is cut off, the battery pack will change from the backup power supply to the main power supply to supply power for the load. After the battery has been used for a long time, the capacity will drop seriously and cannot meet The backup time is required to become a waste battery; the waste battery must be scrapped and returned to

Abstract

The invention discloses a storage battery four-quadrant energizing repair device and method. The system comprises a control unit, a power supply load switching unit and a voltage and current four-quadrant conversion unit, the control unit is connected with the voltage and current four-quadrant conversion unit and the power supply load switching unit, the power supply load switching unit is connected with the voltage and current four-quadrant conversion unit, and the voltage and current four-quadrant conversion unit is connected with positive and negative electrodes of a storage battery. According to the invention, four-quadrant bidirectional charging and discharging energization of the battery can be integrally and automatically realized, and the function of each quadrant does not need tobe completed by multiple pieces of equipment; therefore, the battery energizing efficiency is greatly improved, and the battery energizing cost is effectively reduced.
