Next level heating

Thermal management is a broad and dynamic field, shaping the future of mobility and comfort. 
At Webasto, we continuously push boundaries to develop cutting-edge solutions that make vehicle heating smarter and optimize thermal management. Our commitment to innovation ensures that every product delivers performance, reliability, and a better experience for our customers.

Heated Chiller

The Heated Chiller is a newly developed, highly integrated component, tailored to meet the complex thermal demands of modern electric vehicles.

Our newly developed high voltage heater combines the advantages of the following components and replaces them: a chiller, a battery heater and a refrigerant heater. It connects and serves both coolant and refrigerant heating circle and offers one holistic thermal management. 

By integrating multiple functions into a single system, the number of required components can be reduced compared with conventional system architectures.

Heated Chiller integrating chiller, battery heater and refrigerant heater in one compact module for Webasto vehicle electrification and thermal management systems.

Simplified vehicle architecture

With deep understanding of vehicle architecture and system integration, Webasto has developed this innovation alongside customer demands, drawing from its extensive experience in thermal management and its batteries competence. With the Heated Chiller, passenger comfort can be supported even under extreme temperatures, and battery lifetime may be positively influenced while creating opportunities for cost savings and helping to reduce the complexity of the overall vehicle architecture.

Next Generation Coolant Heater

For systems that demand particularly high heating performance, Webasto's High Voltage Heaters (HVH) provide a suitable solution for applications with demanding heating performance requirements. The powerful heating system for hybrid and electric vehicles tempers both the vehicle cabin and the batteries. 

Webasto next generation coolant heater

With its Next Generation Coolant Heater, Webasto is launching an electric heating system built on a platform basis, allowing it to be flexibly adapted to meet different customer requirements.

 

It is based on innovative heating technology that is integrated into an installation-space-optimized heat exchanger and is suitable for both 400- and 800-volt vehicle architectures. Its heat output is scalable between three, six and nine kilowatts. Webasto’s Next Generation Coolant Heater moreover facilitates a flexible interface with the customer’s vehicle architecture, irrespective of voltage and heat output. By taking a modular approach, we support a high degree of production automation and flexible manufacturing across larger production volumes.

Material and Space Optimization

The Heated Chiller and the Next Generation Coolant Heater are a diversification of our HVH portfolio. The platform concepts have been specifically designed to make efficient use of available installation space while helping to reduce weight and material usage.

Sustainable materials for the production of high-voltage heating systems

The Heated Chiller combines three vehicle components (chiller, battery heater and cabin heater) into a single unit, which can help reduce weight and minimize required installation space.

 

The Next Generation Coolant Heater reduces its aluminum content by almost 50 percent compared to the HVH 10 kW Variant, ensuring a weight reduction of 30 percent. 

 

Just like the HVH family, both the Heated Chiller and the Next Generation Coolant Heater are free from rare earth materials and have been designed with material efficiency in mind.

Success story continues 

Webasto has been producing high-voltage coolant heaters in series since 2015 and the first 800-volt coolant heater - the HVH 100 - since 2019.

 

The high-voltage heater delivers up to 10 kilowatts of heating power with an efficiency of over 95 percent. Its successor, HVH 100 Compact, has been designed with compact dimensions and reduced weight while maintaining comparable heating performance. Our portfolio also includes the HVH 120, a powerful solution especially for commercial vehicles.

 

The device delivers a heating output of up to 12 kilowatts.
