5KW Ptc Coolant Heater For Ev Car

5KW PTC Coolant Heater for EV Car

A positive temperature coefficient heater (PTC) is composed of a PTC ceramic heating element and an aluminum tube. It has the advantages of small thermal resistance and high heat transfer efficiency, and requires little modification on the body of a fuel vehicle. Therefore, electric vehicles use Vapor compression refrigeration cycle refrigeration plus PTC heating is used to achieve thermal management of the passenger compartment. Unlike fuel vehicles, which are powered by fuel, electric vehicles are powered by power batteries.

 

When an electric vehicle is operating normally, the power battery discharges and generates heat, causing the temperature to rise, requiring the battery to be cooled down. Battery cooling methods mainly include air cooling, liquid cooling, phase change material cooling, and heat pipe cooling. Air cooling is widely used in electric vehicles because of its simple structure, low cost, and easy maintenance. The main form of thermal management at this stage is that each independent subsystem meets the needs of thermal management.
