The invention discloses an anti-overcharge method and device for a battery in a vehicle, the vehicle and a storage medium. The method comprises the steps that the overcharge power of a battery in a vehicle is obtained, and the overcharge power is used for representing the overcharge degree of the battery; in response to the fact that the overcharge power is smaller than an overcharge power threshold value and the overcharge coefficient of the battery is larger than an overcharge coefficient threshold value, the battery is controlled to supply power to high-voltage accessories in the vehicle, and the overcharge coefficient is used for representing the continuous charging capacity of the battery after the battery reaches the full-charge state; and in response to the fact that the overcharge power is larger than the overcharge power threshold value, the demand power of a generator in the vehicle is reduced, and the demand power is used for representing the demand degree of the generator for charging a battery. The technical problem that the battery is overcharged in the driving process of the vehicle is solved.

    本发明公开了一种车辆中电池的防过充方法、装置、车辆和存储介质。其中,该方法包括:获取车辆中电池的过充功率,其中,过充功率用于表征电池的过充程度;响应于过充功率小于过充功率阈值,且电池的过充系数大于过充系数阈值,控制电池向车辆中高压附件供电,其中,过充系数用于表征电池在达到满电状态后继续充电的能力;响应于过充功率大于过充功率阈值,减小车辆中发电机的需求功率,其中,需求功率用于表征发电机向电池进行充电的需求程度。本发明解决了车辆在驱动行驶过程中电池过充的技术问题。
