A charging station assembly capable of generating and delivering a conditioned airflow while charging a battery of a vehicle. The temperature and flow rate of this conditioned airflow may be controlled based on the ambient conditions and battery status. The conditioned airflow may be directed toward an outside heat exchanger of a refrigerant system of the vehicle to enhance capacity. The conditioned airflow may also be routed to a battery pack for direct cooling or heating through additional ventilation system. In hot ambient conditions, the charging station provides cool air to facilitate battery cooling. In cold ambient conditions, the charging station provides hot air to facilitate battery heating. This charging station assembly shifts the load from the vehicle refrigerant system to the charging system, thereby improving battery thermal management capability, while eliminating the need for an oversized refrigerant system.
