The invention provides a vehicle power supply control method and device for an electric vehicle. The method comprises the steps that whether a power battery of a target vehicle breaks down or not is detected; when the power battery breaks down, the current whole vehicle speed of the target vehicle is detected; if the current whole vehicle speed is smaller than the preset whole vehicle speed threshold value, whether the current gear of the target vehicle is the P gear or not is judged; when the current gear is the P gear, whether the current vehicle mode of the target vehicle is a standby mode or not is judged; and when the current vehicle mode is the standby mode, controlling the target vehicle to cut off the power supply of the turn-off load after a preset time period. According to the method and device, when the electric automobile has the thermal fault, energy supply of the whole automobile system can be adjusted, normal operation of the temperature control system is guaranteed to reduce or eliminate the probability of the thermal runaway fault of the whole automobile, and therefore the using safety of the automobile is improved.

    本申请提供一种电动汽车整车电源控制方法及装置,该方法包括:检测目标车辆的动力电池是否发生故障;当动力电池发生故障时,检测目标车辆的当前整车车速;若当前整车车速小于预设整车车速阈值,则判断目标车辆的当前挡位是否为P挡;当当前挡位为P挡时,判断目标车辆的当前车辆模式是否为待机模式;当当前车辆模式为待机模式时,在预设时间段之后控制目标车辆切断可关断负载的电源。该方法及装置能够在电动汽车发生热故障时,调整整车系统供能,保证温控系统正常运作以降低或消除整车发生热失控故障概率,从而提高车辆使用的安全性。
