The invention provides a vehicle energy-saving method and system which are applied to the technical field of automobiles and can save vehicle energy. The method comprises the steps that when the allowable charging power of a vehicle is small, namely in the scenes of low air temperature, high air temperature and high battery remaining capacity, the maximum demand power of at least one vehicle accessory is large, and if the energy recovery power of the vehicle is large (the high-power recovery working condition), the vehicle accessory can consume energy recovered by the vehicle; and when the energy recovery power of the vehicle is relatively low (under a non-power recovery working condition), the vehicle accessories can consume the energy of the battery.

    本申请提供一种车辆节能方法及系统,应用于汽车技术领域,可以节省车辆能量。该方法包括:在车辆的许用充电功率较小,即处于低气温、高气温、电池高剩余电量场景中,至少一个车辆附件的最大需求功率较大时,若车辆的能量回收功率较大(大功率回收工况)时,则车辆附件可以消耗车辆回收的能量;当车辆的能量回收功率较小(非功率回收工况)时,则车辆附件可以消耗电池的能量。
