The invention discloses a battery protection method, device and equipment, a storage medium and a product, and relates to the technical field of battery protection, and the battery protection method comprises the following steps: in a battery charging process, detecting a charging cut-off signal; when the charging cut-off signal is detected, the current charging current is detected; when the current charging current is greater than a preset charging current, continuously charging the battery with the preset charging current, and recording the charging duration of continuous charging; and when the charging duration of continuous charging reaches a preset duration, ending charging. Compared with the prior art, the protection current trickle charging is added after the high-current charging of the battery is finished, so that the problem that the over-voltage or lithium precipitation risk of a battery cell is caused under a serious condition due to the fact that a relatively large voltage difference is easily generated between different branches after the high-current charging is finished and then a relatively large ring current is generated between the branches is solved.
本发明公开了一种电池保护方法、装置、设备、存储介质及产品,涉及电池保护技术领域,公开了电池保护方法,包括:在电池充电过程中,检测充电截止信号;在检测到所述充电截止信号时,检测当前充电电流;在所述当前充电电流大于预设充电电流时,以所述预设充电电流继续为电池进行充电,并记录继续充电的充电时长;在继续充电的所述充电时长达到预设时长时结束充电。本发明通过在电池经过大电流充电结束后加入保护电流涓流充电,与现有技术相比,本发明解决了在大电流充电结束后不同支路间容易产生较大压差,进而在支路间产生较大环流,严重情况下会造成电芯过压或者析锂风险的问题。
