The High Voltage Electrical PTC Heater Elements for Electric and Hybrid Vehicles
● Heating comfort for modern vehicle concepts
Modern, fuel-efficient vehicle engines provide too little waste heat to ensure a sufficient and comfortable temperature in the passenger compartment. With additional electrical air and water heaters (PTC heaters), Espar catem offers an effective solution to this challenge.
The PTC heater elements can be adapted without difficulty to customized applications and can also be used decentrally in the vehicle, for example for targeted neck-level heating. This know-how is already operational in more than 25 million vehicles around the globe.
With high-voltage applications up to 500 V, Espar catem is already developing mass-production-ready PTC heaters. They can be installed in very little space in future vehicle generations with hybrid, electric and fuel cell drives. These PTC heater elements cover an output range of up to 7 kW and can be adapted to the typical voltage ranges, providing highly efficient heating even in new vehicle concepts.
● PTC heater elements for electric and hybrid vehicles
In the future, the share of electrically driven or electrified vehicles will increase considerably around the globe. The success of hybrid technologies will promote this process. Electric vehicles, and fuel-cell powered vehicles in the longer term, will also contribute as they become more prevalent.
When running, these vehicles do not generate sufficient waste heat to heat the interior to the usual comfort and safety standards. The innovative and reliable PTC technology from Eberspächer catem is the solution: additional electrical heaters for voltage ranges up to 500 V and heat output ratings of up to 7 kW can be realized even if the available installation space is limited.
Espar catem builds on its diverse experience gained on numerous development and series production projects. Heaters with integrated power electronics and bus communication designed specifically on the basis of electric operation have already been developed to series production readiness in order to heat these vehicles.
Espar catem PTC heater elements are the ideal solution, particularly for hybrid and battery-operated vehicles. They are easily adaptable to different voltage ranges and cover a broad performance spectrum.
Espar catem PTC air heater elements and PTC water heater elements are already available for these special applications.
