MAHLE has developed an innovative heat recovery system for efficient cabin heating in electric vehicles. MAHLE HeatX Range+ reduces the energy demand for air conditioning in electric vehicles by approximately 20 percent compared to conventional exhaust air systems. As a result, drivers benefit from extended range per battery charge and first-class interior air quality. Thanks to its modular design, manufacturers can easily and cost-effectively integrate the new system into existing vehicle architectures.
The new heat recovery system has no adverse effect on the air flow performance or acoustic behaviour of the vehicle air conditioning system. In implementing this innovative energy recovery technology, MAHLE drew on its extensive experience developing and manufacturing vehicle climate control systems. The current heat recovery layout is designed for refrigerant R1234yf and can be adapted to all alternative refrigerants with only minor modifications.
