A control method and system for power battery charging, a program product and a medium, the control method comprising: acquiring an automobile charging state, the automobile charging state at least comprising a fast charging state and a slow charging state; calculating the number of quick charging times of the automobile in a quick charging state; judging whether the vehicle has an over-slow charging state and a slow charging record of slow charging to full charging; when the fast charging frequency is greater than a preset charging frequency and the slow charging record does not exist, starting a power battery maintenance mode; when the automobile is in a fast charging state and the SOC of the battery is larger than or equal to a first preset SOC, request charging current in a battery maintenance mode and request charging current in a non-battery maintenance mode are obtained and taken small to serve as fast charging request current; and when the automobile is in the fast charging state and the battery SOC is larger than or equal to the second preset SOC, the power battery maintenance mode is closed. The invention solves the problem that the battery charging mode cannot actively judge the charging habit of the user and affects the power utilization safety of the user.

    一种用于动力电池充电的控制方法、系统、程序产品及介质,所述控制方法包括获取汽车充电状态,所述汽车充电状态至少包括快充电状态和慢充电状态;计算汽车快充电状态下的快充电次数;判断汽车是否存在过慢充电状态且慢充至满电的慢充电记录;当所述快充电次数大于预设充电次数且不存在所述慢充电记录时,开启动力电池维护保养模式;当汽车处于快充电状态且电池SOC大于等于第一预设SOC时,分别获取电池维护保养模式下和非电池维护保养模式下的请求充电电流并取小,作为快充请求电流;当汽车处于快充电状态且电池SOC大于等于第二预设SOC时,关闭动力电池维护保养模式。本发明解决了电池充电方式不会主动判断用户的充电习惯,影响用户用电安全的问题。
