PTC Heaters for Electric Vehicles
Taiwan KLC Corporation offers standard electric auxiliary heaters for the future generations of electric, hybrid and fuel cell vehicles.
As more energy-efficient diesel and hybrid-powered vehicles take to the roads, recent trends toward engines with lower heat rejection rates in production vehicles has progressively reduced the amount of available "waste" heat for compartment heating. In an effort to reduce compartment heat up time while increasing the compartment temperature, a new PTC (positive temperature coefficient) electric heater system has been developed to supplement the performance of current hot water based vehicle heaters.
The PTC supplemental heater system features automatic power adjustment in response to ambient temperature conditions and HVAC fan speed, along with self regulation of the heater temperature. In addition, the power draw of the PTC heater can be matched automatically to the available electrical power level for all vehicle operating conditions.

Features of the new PTC auxiliary heater models
- Multiple heater stages are possible. Single-stage mini-heaters for decentralised heating can be produced just as readily as powerful four- or five-stage heaters with electronic control
- Twice the thermal safety and longer service life: In all high-output models, the switching elements and the PC boards are thermally isolated from each other by a bus bar; in addition, an excess temperature cut-out is incorporated into the PTC electronics
- Shorter development times for customer-specific applications and reduced tooling manufacturing time
- Withstands external electric shock
