Valeo unveils free EV air conditioning training course
Valeo Service UK has introduced a new free training module introducing technicians to the key principles behind EV air conditioning systems.
Available on its Valeo Tech Academy platform and presented by technical trainer Stewart Lynch, the session explores the evolving role of vehicle air conditioning systems and their critical function in battery thermal management.
It breaks down the core differences in compressor technology. While internal combustion engine (ICE) vehicles use belt-driven compressors lubricated with PAG oil, BEVs rely on electrically driven compressors powered by the high-voltage battery. These offer greater precision and energy efficiency, thanks to sensor-driven input and inverter-based control.
Temperature, solar, and humidity sensors feed data into the electronic control unit (ECU), which works with the inverter to modulate compressor speed and protect against voltage spikes and overheating. Understanding how these systems work, and how to diagnose faults, is now essential for workshops.

Lynch said:
“When it comes to EVs, air conditioning isn’t just about keeping the cabin cool. It plays a key role in regulating battery temperature, which is essential for performance, safety and longevity.”
The latest module forms part of a growing library of free and IMI-certified training which covers topics from traditional maintenance and repair to hybrid and electric vehicle systems, as well as advanced driver assistance systems (ADAS).
