The invention discloses a control method and device for preventing power shortage of a storage battery and a vehicle, and relates to the technical field of electric automobiles, the control method comprises the steps that the descent rate of electric energy parameters of a first storage battery within a preset time interval is obtained, and the electric energy parameters comprise electric quantity parameters; when the electric quantity parameter is greater than or equal to a first preset threshold value, comparing the relationship between the descent rate and the first rate, and when the descent rate is greater than the first rate, controlling to close the first power consumption equipment; when the electric quantity parameter is smaller than a first preset threshold value and larger than or equal to a second preset threshold value, the relationship between the descent rate and a second rate is compared, and when the descent rate is larger than the second rate, the second power consumption device is controlled to be turned off; when the electric quantity parameter is smaller than the second preset threshold value, electric energy output of the first storage battery is controlled to be cut off, and the technical problem that under the condition that the electric vehicle is in a dormant state or parked for a long time, the storage batteries lack electricity, and consequently the vehicle cannot be normally started can be solved.

    本申请公开一种防止蓄电池亏电的控制方法、装置及车辆,涉及电动汽车技术领域,上述控制方法包括:获取第一蓄电池的电能参数在预设时间间隔内下降速率,电能参数包括电量参数;在电量参数大于或等于第一预设阈值的情况下,比对下降速率与第一速率的关系,在下降速率大于第一速率的情况下,控制关闭第一耗电设备;在电量参数小于第一预设阈值且大于或等于第二预设阈值的情况下,比对下降速率与第二速率的关系,在下降速率大于第二速率的情况下,控制关闭第二耗电设备;在电量参数小于第二预设阈值的情况下,控制切断第一蓄电池的电能输出,能够解决电动车辆在休眠状态或者是长时间停放的情况下,蓄电池发生亏电导致车辆无法正常启动的技术问题。
