Webasto Heated Chiller Streamlines EV Thermal Management with 3-in-1 Design

Thermal control for battery performance, fast charging, and cabin comfort
Webasto introduces the Heated Chiller, a dedicated thermal solution engineered for the complex requirements of modern electric vehicles. With cooling, battery conditioning, and interior heating combined into one device, the system addresses the growing demand for compact and highly efficient thermal architectures in EVs—particularly for applications involving high-voltage batteries, fast charging, and heat-pump-based cabin conditioning.

Replacing multiple components with one integrated system
Conventional EV platforms rely on several separate thermal components, each requiring individual routing, controls, and sealing points. This increases installation effort, system weight, and the likelihood of faults. The Heated Chiller consolidates these functions into a single module, significantly reducing complexity, material usage, and overall system cost. At the same time, it ensures batteries reach optimal temperatures faster, improving range and extending battery life while delivering reliable comfort in both hot and cold climates.

Engineered for modern EV thermal demands
The Heated Chiller performs three core tasks essential to vehicle efficiency and performance. It heats the coolant to bring the battery to its ideal operating temperature, ensuring consistent power delivery and longevity. It cools the battery circuit during load-intensive situations—such as fast charging or dynamic driving—to prevent thermal stress. It also directly heats the refrigerant to support heat-pump systems, improving cabin heating efficiency during low outdoor temperatures and reducing reliance on energy-intensive resistive heaters.

A compact, efficiency-driven solution for future EV architectures
By merging key thermal functions into one unit, Webasto provides automakers with a scalable solution that simplifies integration while improving energy efficiency and comfort. Designed with the company’s long-standing expertise in thermal systems and battery technology, the Heated Chiller supports the shift toward lighter, more efficient, and more sustainable electric vehicle platforms.
