BorgWarner, a global leader in propulsion systems for
combustion, hybrid and electric vehicles, has announced its innovative High
Voltage Coolant Heater as part of the company’s Battery and Cabin Heater
families. The technology improves battery performance by keeping the battery’s
operating temperature within an optimal operating range and providing a
consistent temperature distribution inside the battery pack and its cells.
The High Voltage Coolant Heater is available in two
versions: Single Plate and Dual Plate. Compared to its Single Plate version
which is responsible for either the thermal management of the battery or the
heating of the cabin, the Dual Plate Heater manages both tasks at the same
time. In addition, it provides up to 80 percent more heat transfer surface as
it has two heater plates. Both versions are integrated into a robust aluminum
housing that allows for excellent electromagnetic shielding. As the heat
packages within this application are covered by the coolant, the heat power
losses are minimized providing higher efficiency and extending the
battery-powered driving range.
BorgWarner’s latest High Voltage Coolant Heater features a
thick film heating element (TFE). A compact contour enables flexible sizes and
shapes while low thermal mass results in fast response times. The innovative
technology not only offers high thermal power density, it also allows for
direct temperature sensing. Different designs of BorgWarner’s High Voltage
Coolant Heater are suitable for application with supply voltages between 180
and 800V, offer a power range of between 3 and 10 kW, and are suitable for a broad
range of applications. In addition, an intelligent safety concept prevents the
High Voltage Coolant Heater from overheating during high electricity flow. The
system recognizes various situations and can react to each. With its high
thermal power density and fast response times due to its low thermal mass, the
efficient technology also extends pure electric driving range by using less
power from the battery. In addition it allows comfortable cabin temperatures to
be generated in a short time.
“As demand for EVs and HEVs increases, thermal management is
receiving growing attention. Our engineers developed two flexible, efficient
systems to provide fast temperature response in daily use,” said Joe Fadool,
President and General Manager, BorgWarner Emissions & Thermal Systems.
“BorgWarner’s expertise in heating solutions helps automakers improve the
overall efficiency of their applications, meeting new mobility trends and the
demand for clean vehicles.”
