The invention provides a 48V energy management method and system based on a plateau long-term climbing working condition and a vehicle. The 48V energy management method based on the plateau long-term climbing working condition comprises the following steps that road condition variable parameters are set; when the vehicle accelerates, the motor calls motor power-assisted torque according to different road condition variable parameters so as to start a power-assisted mode; and when the power-assisted mode is finished and the charge capacity of the battery is lower than a set threshold value, starting a driving power generation mode to supplement the battery power so that the charge capacity of the battery is greater than the set threshold value. According to the 48V energy management method based on the plateau long-term climbing working condition, the driving power generation mode is started after the motor completes assistance, the consistency of the driving feeling of a driver can be guaranteed, and the overtaking safety of the vehicle can be improved.

    本发明提供一种基于高原长期爬坡工况的48V能量管理方法、系统和车辆,基于高原长期爬坡工况的48V能量管理方法包括以下步骤:设置路况变量参数;当车辆加速时,电机根据不同路况变量参数调用电机助力扭矩以开启助力模式;当助力模式结束且电池电荷容量低于设定阈值时,启用行车发电模式补充电池电量以使电池的电荷容量大于设定阈值。根据本发明实施例的基于高原长期爬坡工况的48V能量管理方法,通过在电机完成助力后启动行车发电模式,该方法不仅能够保证驾驶员驾驶感的一致性,而且能够提升车辆的超车安全性。
