Firmware upgrading method and device for battery IC, equipment and medium

The invention relates to the technical field of battery design, and discloses a firmware upgrading method, device and equipment for a battery IC and a medium, and the method comprises the following steps: obtaining use temperature data and use capacity data of a battery in a preset historical time period; matching a target use scene from a plurality of preset candidate use scenes through the use temperature data and the use capacity data; matching a corresponding target charging mode from a plurality of preset candidate charging modes according to the target use scene; and updating firmware of the battery IC according to the target charging mode so as to charge the battery through the target charging voltage and the target cut-off current limited in the updated firmware. The accuracy of the charging mode is improved through matching of historical data, the charging duration of the battery and the time for keeping the high voltage are changed through the charging voltage and the cut-off current, damage to the
