Abstract

The invention discloses a charging management method for electric vehicles. The method comprises the following steps: (S1) connecting a power supply, driving a battery charger to charge at a constant current by a constant-current drive circuit and entering the step (S2) when the electric quantity in the battery charger reaches 30%-70% of rated electric quantity of a motor; and (S2) cutting off the constant-current drive circuit by a control system, starting a constant-voltage drive circuit to drive the battery charger to further charge at a constant voltage, and simultaneously distributing the residual electric energy in the battery charger to the other constant-current charging battery chargers. According to the charging management method, the constant-current drive circuit drives the battery charger to quickly charge to a certain amount of electric quantity at the constant current, switches into constant-voltage charging and distributes the residual electric energy in the battery charger to the other constant-current charging battery chargers, so that waste of the residual electric energy is avoided; the charging management method is relatively environment-friendly; and a plurality of battery chargers can achieve charging for a plurality of electric buses, so that the charging management method is relatively fast.
