The present application relates to a charging control method and device, electronic equipment, and a computer-readable storage medium, including: detecting deformation of a battery to obtain a deformation detection result, and monitoring the number of charge and discharge times of the battery to obtain the current number of charge and discharge. The charging process of the battery is controlled according to the deformation detection result and the current charge and discharge times. Among them, the abnormal deformation of the battery can be obtained by detecting the deformation of the battery, and the service life of the battery can be obtained by monitoring the charging and discharging times of the battery. Therefore, the charging process of the battery is carried out according to the deformation detection results and the current charging and discharging times Control can control the battery to be charged within a safe range after considering the abnormal deformation and service life of the battery, so as to prevent unsafe events such as battery explosion or battery spontaneous combustion.
