The invention provides a high-rate charging temperature control method for a battery pack. A ventilation channel is arranged in the battery pack, an air inlet and an air outlet are formed in a shell of the battery pack, the air inlet, a ventilation channel and the air outlet are sequentially communicated with one another, cooling airflow in the ventilation channel exchanges heat with cells in thebattery pack, heat of the battery pack is brought to the outside through flowing of the cooling airflow in the ventilation channel, and temperature control in the charging process of the battery packis achieved; and the battery pack is located in the whole vehicle or equipment, the charging equipment and the air cooling equipment are located outside the whole vehicle or equipment, the charging equipment is used for charging the battery pack, and the air cooling equipment is used for providing cooling airflow for a ventilation channel in the battery pack. The method is simple and feasible, theheat dissipation effect is
