The invention discloses a charging control method, device and equipment for an electric vehicle and a storage medium. The method comprises the steps of acquiring the voltage of a charging port of the electric vehicle, the voltage of a discharging port of a charging pile and the actual charging current; obtaining the charging contact resistance according to the voltage of the charging port, the voltage of the discharging port, the actual charging current and the charging contact resistance; acquiring the maximum charging current corresponding to the charging contact resistance from a preset maximum current and charging contact resistance comparison table, wherein the preset maximum current and charging contact resistance comparison table reflects the corresponding maximum charging current when the charging contact resistance with different resistance values do not exceed the maximum temperature threshold value; and adjusting the actual charging current so that the actual charging current does not exceed the maximum charging current. According to the charging control method, device and equipment for the electric vehicle and the storage medium, the charging current is controlled based on the contact resistance, over-temperature of the charging port is avoided, and safety and reliability of the charging process are guaranteed.
