The invention discloses a power-saving mode control method and system and an electric vehicle, and the method comprises the steps: responding to a received power-saving mode opening instruction, entering a power-saving mode, obtaining the current state of charge (SOC) of a storage battery, judging the electric quantity section of the SOC, and starting the power-saving mode; the corresponding vehicle speed limit, the energy recovery intensity and the forbidden system range are matched according to the electric quantity section where the current state of charge (SOC) of the storage battery is located, and the vehicle is correspondingly controlled; wherein different maximum vehicle speed limits, different energy recovery intensities and different system forbidding ranges are preset in different electric quantity sections. By means of the power-saving mode control method, basic driving requirements can be met, the endurance mileage is increased, and mileage anxiety is relieved.

    本发明公开了一种省电模式控制方法及其系统、电动汽车,步骤包括:响应于接收到打开省电模式指令,进入省电模式,获取当前蓄电池的荷电状态SOC并判断其所处电量段,根据当前蓄电池的荷电状态SOC所处电量段匹配出对应的车速限制、能量回收强度和禁用系统范围,并对车辆进行相应控制;其中,不同电量段预设有不同的最高车速限制、能量回收强度和禁用系统范围。通过本发明的省电模式控制方法,能够保证基本驾驶需求,提高续航里程,缓解里程焦虑。
