BorgWarner’s coolant heaters to appear in 2021

BorgWarner’s state-of-the-art coolant heaters are expected to appear in 2021 on the next generation of passenger cars produced by global OEMs. The company has been chosen as a supplier for cabin heating and battery conditioning solutions for several high-volume vehicle programs. 
The new technology was developed to meet the demand for fast-acting solutions as the heat management systems of vehicles increasingly become decoupled from the internal combustion engine.
BorgWarner’s coolant heaters can be used for both passenger cabin heating and improving battery energy performance in electric and hybrid vehicles by offering consistent temperature distribution inside the battery pack and its cells. BorgWarner has engineered two versions – single plate and dual plate. Single plate devices are responsible for either thermal management of the battery or cabin heating, while dual plate versions manage both tasks at the same time while providing up to 80% more heat transfer surface. Both versions are integrated into robust aluminum housings that provide excellent electromagnetic shielding. They have been designed for input voltages between 250 and 500 V. If necessary, there is an 800 V alternative to enable faster battery charging.
