The invention discloses a charging system current-carrying capacity adjusting method and device, a terminal and a medium. The method comprises the steps that related temperature data and current charging current of a charging system and the cell temperature, SOC and cell voltage of a battery pack of a vehicle are obtained; the current temperature and the aging coefficient of the high-pressure part are calculated by adopting the high-pressure part temperature model and the cloud aging model of the vehicle; searching a current-temperature correction coefficient and a current-aging correction coefficient of the high-voltage part through the temperature-current carrying capacity MAP and the aging-current carrying capacity MAP; and through the current-temperature correction coefficient and the current-aging correction coefficient of the high-voltage part, the final charging current of the charging system is obtained through charging MAP calculation. Therefore, according to the embodiment of the invention, the current-carrying capacity of the charging system can be adjusted by combining the temperature sensor in the charging system, the pile end cooling capacity and the aging condition of the high-voltage part estimated by the cloud, and the charging performance is improved.
