114 eMobility The current trend towards electrification is bringing changes with it: the heat manage- ment of modern passenger cars is increas- ingly being decoupled from the internal com- bustion engine, and assistance from auxiliary heating systems is required. To allow pure electric driving for hybrid and electric ve- hicles, solutions that compensate for the lack of heating performance are necessary, es- pecially in winter. These have to work with- out usable exhaust heat – temporarily in hy- brid cars and permanently in electric cars – as well as being energy-efficient so as not to have a negative effect on consumption, range and acceleration. With regard to future-proof heating concepts, BorgWarner’s innovative heat management solutions provide a response to the increasing demand of automotive manufacturers. The company’s Cabin Heater family includes the High-Voltage Coolant Heater (HVCH) and the High- and Low-Voltage Air Heater. The former is also part of BorgWarner’s Battery Heater family. In addition to increased battery-oper- Efficient heating solutions for more battery power and increased comfort in hybrid and electric vehicles By Jürgen Dunsch, Senior Business Development Manager HV Coolant Heaters, BorgWarner Emissions Systems in Ludwigsburg BorgWarner’s efficient high- and low-voltage heating solutions for hybrid and electric vehicles represent the state of the art in terms of comfort and safety and meet the high demands of the automotive industry.
