Battery switch driving module and battery equalization system and device

Abstract

The invention discloses a battery switch driving module which comprises a driving array and a switch array, the driving array comprises a plurality of driving units, the switch array comprises a plurality of switch units, and one driving unit is connected with a bidirectional converter through one switch unit. The other driving unit is connected with one battery of the battery pack through the other switch unit; the driving unit generates a switch driving signal according to the received switch control signal, and the switch unit is connected or disconnected according to the received switch driving signal, so that a current path between the battery pack and the bidirectional converter is connected or disconnected, and the charging and discharging conditions of each battery in the battery pack are adjusted. The charging and discharging control process of each battery in the battery pack can be more convenient and efficient, so that the charge state of each battery can be efficiently adjusted, and the service life of the battery pack is prolonged. Meanwhile, the structure and the connection mode are simple, the size is small, the structure is compact, and replacement and integration are convenient.
