PTC (Positive Temperature Coefficient) heaters are a core component of the thermal management system for new energy electric vehicles, primarily responsible for cabin heating and battery pack thermal management.

Unlike traditional fuel-powered vehicles that utilize engine waste heat for heating, electric vehicles lack a stable source of engine waste heat and therefore require independent heating devices. PTC heaters, due to their superior safety, high heating efficiency, and compact size, have become the most widely used heating technology in electric vehicles. Essentially a semiconductor ceramic heating element, their core characteristic is that their resistance increases with increasing temperature, thereby achieving automatic temperature control and preventing overheating.
