CHARGING CONTROL METHOD AND SYSTEM, AND VEHICLE

The vehicle includes a battery pack. When the battery pack is charged by using a charging gun of a charging pile, battery pack is charged according to smaller value of a first charging current upper limit value of a charging device and a second charging current upper limit value of the battery pack, so that the charging efficiency is improved to the greatest extent, and the charging time is shortened on the premise of ensuring safety, and a situation that the charging time is prolonged as the charging current is set to be too small is avoided; and when the battery pack is charged by using an on-board charging gun, the battery pack is charged according to the smallest value of the first charging current upper limit value of the charging device, the second charging current upper limit value of the battery pack, and a preset charging current value.
