BorgWarner Secures eHeater Business Uplift with Premium European OEM

  • 800V 3kW high voltage coolant heater optimizes battery thermal management to increase battery performance and extend electric vehicle range
  • Robust thick film element technology provides fast response and long product life

BorgWarner has been awarded additional high voltage coolant heater (HVCH) business with a premium European OEM for its mid-size electric vehicle platform, following an initial supply agreement in July 2022 for the OEM’s small electric vehicle platform. The 800V 3kW HVCH single-plate heater will be used to maintain optimal battery temperature on electrified vehicles for the European and Asia-Pacific markets.

“This is a significant volume extension of our high voltage coolant heater program with this European customer,” said Joe Fadool, President and General Manager, BorgWarner Emissions, Thermal and Turbo Systems. “We’re delighted that they continue to choose BorgWarner’s advanced thermal management systems due to their exceptional efficiency and performance and are happy to support our customers with their shift to electrification.”

Thermal management of an electric vehicle’s battery system is essential to achieve optimal performance. By managing the temperature within the battery pack, energy output is maximized, and high thermal power density as well as fast response time are achieved. BorgWarner’s HVCH features a compact design employing the latest thick film heating elements (TFE) on stainless steel. Heat from the TFEs is efficiently transferred to the coolant through a set of fins. The heating unit is packaged in a solid die-cast aluminum housing that provides excellent electromagnetic shielding and resists thermal shock, vibration and mechanical stress for extended product life.

Production of BorgWarner HVCHs for the customer’s electric vehicle is scheduled to start in 2025.
