[Technical Column] Issue 13: Air Conditioning Systems and Challenges of Electric Vehicles

Insufficient heating source! This problem will become more pronounced when fully transitioning to electric vehicles!

In this column, we will discuss the air conditioning methods and challenges of electric vehicles. As shown in the diagram of the refrigeration cycle, the air that exchanges heat with the refrigerant in the evaporator becomes cold air, which is used for cooling in the summer. However, to achieve the preferred temperature for the occupants, it is necessary to mix this cold air with warm air generated by the heater core. The hot water entering the heater core is the cooling water from the radiator. In recent years, the popularity of hybrid vehicles has led to a shortage of this heating source. This is due to the reduced heat generation from the engine as it operates intermittently. Especially in winter, due to the lack of heating, methods such as electric heaters (PTC heaters) have been put into practical use to supplement the heating. When fully transitioning to electric vehicles, this issue will become even more pronounced. *For more details on the column, you can view it through the related links.
