A major OEM's supplier has contracted BorgWarner, a provider of thermal and energy management solutions for automobiles, to supply high voltage coolant heaters (HVCH) for three electric vehicle (EV) platforms. The 800V HVCH developed by BorgWarner features a compact and lightweight design, enabled by its thick-film heating and brazed aluminium fin technologies.
The solution meets the customer's demands for smaller and lighter dimensions. Moreover, the heater provides efficient heat transfer in the 800V architecture required for fast charging. Thanks to low thermal mass and high efficiency, the 800V HVCH offers quick heating response times and a highly flexible power and coolant connector concept.
These heaters will be incorporated into the supplier's heating and cooling modules, delivering crucial heat to the battery pack and cabin of battery electric vehicles (BEVs). This partnership marks the first joint venture between the companies for a complete vehicle thermal management system.
The President and General Manager of BorgWarner Emissions, Thermal, and Turbo Systems, Joe Fadool, seemed superbly optimistic about strengthening their ties with the global supplier and expanding their collaboration with the OEM. The HVCH technology will play a crucial role in maintaining optimal battery and cabin temperatures, which is a significant challenge in the era of electrification.
BorgWarner's heating solution adheres to the industry's latest safety requirements as safety is of extreme importance to the firm. The system is designed to automatically switch off in case of thermal events or overheating, providing added protection and peace of mind. Aluminium plays a huge part in keeping the heat mechanism under control as it is a poor conductor of heat if compared with metals like gold, silver and copper.
BorgWarner's 800V HVCH is the first of its kind to be launched in North America, representing the company's first 800V HVCH win with the OEM. This achievement builds upon a previous agreement in which BorgWarner directly supplied its 400V solution to the same OEM.
