The role of PTC heaters in electric vehicles

PTC heaters play a variety of key roles in electric vehicles, mainly in the following aspects:

Car interior heating: In cold weather, PTC heaters are used in the heating module of the air conditioning system to transfer heat to the interior of the car by heating the air or coolant to increase the interior temperature and ensure passenger comfort.

Battery preheating: The performance of electric vehicle batteries will significantly decrease in low temperature environments, affecting the cruising range and charging and discharging efficiency. The PTC heater can preheat the battery to keep it within the optimal operating temperature range, improving battery performance and service life.

Defrosting and defogging: The PTC heater can be installed near the windshield to heat the glass surface to quickly remove frost and fog to ensure clear vision for the driver and improve driving safety.
