The invention discloses a hybrid power vehicle type energy management control method. The method comprises the steps that the high-voltage state of a whole vehicle is judged; if yes, the working states of a generator, an engine and a BMS are judged; if the generator does not work and does not need to start the engine, the DCDC power is not limited, and the sum of the AC power, the PTC power and the DCDC power is continuously limited according to P; if the generator does not work and has the requirement for starting the engine, the DCDC power is not limited in the starting process of the engine, and the sum of the PTC power and the AC power is limited to zero; if the BMS is slowly charged and the generator does not work, limiting DCDC, AC and PTC power according to P slow charging; and if the BMS is quickly charged and the generator does not work, the AC, PTC and DCDC power is not limited. According to the hybrid power vehicle type energy management control method, the energy management distribution strategy is designed around different scenes, the battery over-discharge risk can be prevented when the requirement for vehicle use of consumers is met, and the service life of the battery pack is prolonged.

    本发明公开了一种混动车型能量管理控制方法,包括:判断整车的高压状态;若上高压,则判断发电机、发动机和BMS的工作状态;若发电机未工作且没有发动机启动需求,则DCDC功率不受限,根据P持续限制AC、PTC和DCDC功率之和;若发电机未工作且有启动发动机需求,则在发动机启动过程中,DCDC功率不受限,将PTC和AC的功率之和限制到零;若BMS为慢充且发电机未工作,则根据P慢充对DCDC、AC和PTC功率进行限制;若BMS为快充且发电机未工作,则AC、PTC和DCDC功率不受限。本发明的混动车型能量管理控制方法,围绕不同场景设计能量管理分配策略,能在满足消费者用车时,防止电池过放风险,提升电池包使用寿命。
