The invention discloses a charging heat management device and a control method thereof, a charging pile and an automobile, and the device comprises a sampling device which samples the current temperature of an inverter assembly, the current temperature of a charging gun assembly, the current temperature of a vehicle-mounted battery, and the current outdoor environment temperature of the charging pile; the control device controls opening and closing of at least one of the refrigerant plate and the first liquid cooling plate according to at least one of the current temperature of the inverter assembly, the current temperature of the charging gun assembly, the current temperature of the vehicle-mounted battery and the current outdoor environment temperature of the charging pile, and prompts a to-be-charged vehicle side to control opening and closing of the second liquid cooling plate. And heat management of preheating control or cooling control when the vehicle-mounted battery is charged at the charging pile side is realized. According to the scheme, the charging gun and the cooling gun are arranged on the charging pile side, the working state of the temperature control system on the charging pile side is controlled by combining the temperature parameters, high-temperature fast charging and preheating before low-temperature charging of the battery are achieved, the charging efficiency is improved, and the power consumption of the battery is reduced.
