How to design heating and cooling systems for HEV/EVs

Co-authored by Kevin Stauder, systems engineer, automotive body electronics and lighting

For decades, the internal combustion engine (ICE) has run the car as well as the heating and cooling systems. As the automotive industry electrifies and transitions to hybrid electric vehicles (HEVs) with small combustion engines or fully electric vehicles (EVs) with no engine at all, how will the heating, ventilation and air-conditioning (HVAC) systems work?

In this white paper, we will describe the new heating and cooling control modules in 48-V, 400-V or 800-V HEVs and EVs. From there, you will learn about the unique subsystems in these modules with examples and system diagrams, and we’ll finish by reviewing functional solutions for these subsystems to help you start planning your implementation.
