The invention discloses a power generation management method for an extended-range automobile, which comprises the following steps: before the automobile is powered on, monitoring a motor controller, a battery controller, a generator controller and an engine controller in real time, and if a high-voltage power-on condition is met when a system is normal, pre-charging the whole automobile and realizing high-voltage power-on; when the motor controller and the battery controller are both in the normal state, whether the range extending system has a fault or not is judged, and if not, a battery pack high-voltage relay is attracted after the whole vehicle is pre-charged, so that high-voltage power-on is conducted; if the generator controller or the engine controller breaks down, it is judged that the range extending system breaks down, and if the motor controller and the battery controller are both in the normal state at the moment, the whole vehicle can still be pre-charged, and high-voltage power-on is achieved. According to the invention, the fault protection performance and safety performance of the whole vehicle can be improved.
本发明公开了一种增程式汽车的发电管理方法,包括:对车辆上电前,实时监控电机控制器、电池控制器、发电机控制器和发动机控制器,若系统均正常时满足高压上电条件,则对整车进行预充并实现高压上电;在电机控制器和电池控制器均处于正常状态时,判断增程系统是否存在故障,如果否,则整车预充完成后吸合电池包高压继电器,以进行高压上电;若发电机控制器或发动机控制器发生故障,则判定增程系统存在故障,若此时电机控制器和电池控制器均处于正常状态,则整车仍可进行预充并实现高压上电。本发明能提高整车故障的保护性能和安全性能。
