The invention discloses a vehicle electricity guarantee control method and system and a vehicle, and the vehicle electricity guarantee control method comprises the steps that the current remaining electric quantity of a power battery and the target power generation power of a power generator are obtained; judging whether the current residual electric quantity exceeds a preset first default electric quantity value or not; if the preset default electric quantity value is exceeded, controlling the generator to continuously work at the target generated power; and if the preset first default electric quantity value is not exceeded, increasing the target generated power, and controlling the generator to work according to the increased target generated power. If the electric quantity does not exceed the preset first default electric quantity value, the target generation power is increased to avoid further decreasing of the remaining electric quantity of the power battery and avoid shortening of the service life of the power battery due to long-time use of the power battery under the condition of too low electric quantity.
本申请公开了一种车辆保电控制方法、系统及车辆,其中,该车辆保电控制方法包括:获取动力电池的当前剩余电量,以及发电机的目标发电功率;判断当前剩余电量是否超过预设第一默认电量值;若超过预设默认电量值时,控制发电机以目标发电功率继续工作;若未超过预设第一默认电量值时,增大目标发电功率,并根据增大后的目标发电功率控制发电机工作。若未超过预设第一默认电量值时,增大目标发电功率,以避免动力电池的剩余电量进一步递减,避免动力电池在电量过低的情况下长时间使用,导致动力电池的使用寿命缩短。
