Abstract: A controller with battery recharge protective function is disclosed in this invention. The controller is used for protecting a battery module. When the battery module is in a protective state, a recharge protection circuit of the controller is activated. A charging current from a positive recharge terminal flows into one pin of the controller. Afterward, the charging current passes the recharge protection circuit, flows out through another pin of the controller, and then returns to a negative recharge terminal. Accordingly, the recharge protection circuit makes the charging current bypass the battery module, so as to prevent the battery module from being damaged.
