FIELD: physics; electricity.
SUBSTANCE: invention relates to a battery module, a charging method and a charging device, an electronic device and a readable data medium. Accumulator module includes first storage battery and discharge circuit. Discharge circuit is in parallel connected to positive electrode and negative electrode of the first accumulator battery. Discharge circuit is configured to discharge first storage battery in accordance with control signal during charging of first storage battery.
EFFECT: technical result is slower expansion of positive and negative electrodes during charging and consumption of electrolyte, as well as preventing the formation of a gate on positive and negative electrodes to ensure service life of the first battery.
