The invention provides an energy recovery method, a power supply system and a vehicle comprising the power supply system. The energy recovery method comprises the following steps that S100, whether the vehicle is in an energy recovery state or not is judged, if not, the step S300 is executed, if yes, whether the residual electric quantity of a low-voltage storage battery of a power system is larger than a residual electric quantity calibration value or not is judged, and if yes, the step S400 is executed; and S410, reducing the voltage of the power supply system to discharge the low-voltage storage battery if the accumulated electric quantity increment of the low-voltage storage battery is greater than the first electric quantity calibration value. According to the technical scheme, efficient execution of energy recovery is achieved, the low-voltage storage battery can be controlled to supply power to electric appliances of the whole vehicle, the recovered energy is released in time, energy consumption of a vehicle power source is reduced, the energy saving performance of the vehicle is improved, and therefore the energy utilization rate and the economic performance of the vehicle are improved.

    本申请提供一种能量回收方法、一种电源系统及包括所述电源系统的车辆。所述能量回收方法包括以下步骤:S100:判断车辆是否处于能量回收状态,如否,执行步骤S300:判断电源系统的低压蓄电池的剩余电量是否大于剩余电量标定值,如是,执行步骤S400:判断在当前驾驶循环内,低压蓄电池的累计电量增加量是否大于第一电量标定值,如是,执行步骤S410:降低电源系统的电压,使得低压蓄电池放电。根据本申请的技术方案,实现了能量回收的高效执行,并且能够控制低压蓄电池向整车电器的供电,实现了回收能量的及时释放,降低了车辆动力源的能量消耗,提高了车辆的节能性,从而提高了车辆的能量利用率和经济性能。
