From simple electric heaters to complex electric heating and air conditioning systems for driver cabs and vehicle batteries - our solutions are specially produced for vehicles with electric and fuel cells. 

Protection against accidental contact with high-voltage systems and fire resistance are particularly important here.

In addition to classic electrical heating and air conditioning systems, Wölfle also specialises in electrical battery and component cooling systems. These systems are always adapted to the requirements of our customers and thus enable optimal functionality and efficiency:

  • Heating and cooling capacity up to 10kW
  • Passive cooling at corresponding outside temperatures
  • Active cooling via a cooling circuit (R134a/R1234yf/R290)
  • Electric water heating
  • Heating via reversing water circuit (heat pump)
  • High-voltage components up to 850 VDC
  • Constant temperature control using a model
  • Communication via CAN bus (J1939, UDS, Sleep/WakeUp, ..), LIN bus, PWM, optional: AUTOSAR

The Wölfle control integrated in our heating and cooling systems enables a constant temperature of the built-in batteries or components in all functional positions and
thus significantly increase the service life.
