The invention provides a battery charging method and device, a medium and a vehicle, and relates to the technical field of batteries. The method comprises the steps that according to one or more of environment temperature information, battery temperature information, charging current information, refrigeration starting threshold value information and refrigeration closing threshold value information, predicted charging duration and predicted maximum battery temperature are determined; determining an allowable charging duration according to the current time and the deadline; if the allowable charging duration is greater than the predicted charging duration and the predicted maximum temperature of the battery is greater than a preset temperature threshold, determining a current reduction coefficient; and determining a request current according to the charging current information and the current reduction coefficient, and charging the battery according to the request current. Therefore, under the condition that the vehicle use of a user is not influenced, when the highest temperature of the battery is predicted to be higher than the preset temperature threshold value, a current reduction mechanism is automatically started, and the battery is protected from overheating damage by reducing the charging current, so that the service life of the battery can be prolonged and the safety of the battery can be improved while the energy consumption of battery charging is reduced when the battery is charged.

    本申请提供了一种电池充电方法、装置、介质及车辆,涉及电池技术领域。该方法包括:根据环境温度信息、电池温度信息、充电电流信息、制冷开启阈值信息和制冷关闭阈值信息中的一种或多种,确定预计充电时长和预计电池最高温度;根据当前时间和截止时间确定允许充电时长;若允许充电时长大于预计充电时长且预计电池最高温度大于预设温度阈值则确定降流系数;根据充电电流信息和降流系数确定请求电流,并根据请求电流对电池充电。由此,在确保不影响用户用车的情况下,当预计电池最高温度大于预设温度阈值时自动启动降流机制,通过降低充电电流保护电池免受过热损害,从而在对电池充电时,能够在降低电池充电的能耗的同时,提高电池的寿命和安全性。
