Positive Temperature Coefficient (PTC) Heating Unit
KUS Positive Temperature Coefficient (PTC) water heating units are used in pure battery electric, hybrid electric, and fuel cell vehicles. PTC heaters utilize electricity to supply efficient heat control for various vehicle systems, including in-vehicle air conditioning and battery thermal management.
Models and Specifications:
PTC heaters help provide heat sources for in-vehicle air conditioning systems and battery thermal management. This new technology allows the PTC heater to offer an automated heating system. PTC heaters generate more heat than traditional heating elements meaning less electricity is needed to create the same amount of heat. This allows electric vehicles to improve cruising ranges, safety, lower cost, and offer a more compact format.
The overall structure of PTC heaters comprises radiators (including PTC heating packs), coolant flow channels, a central control board high/low-pressure connector, and an upper shell.
This ensures stable power, high heating efficiency, and constant temperature control for various applications and designs.
