Valeo Service UK has released a new free training module on its Valeo Tech Academy platform, offering technicians a clear and accessible introduction to the key principles behind battery electric vehicle (BEV) air conditioning systems.
Presented by Valeo technical trainer Stewart Lynch, the session explores the evolving role of vehicle air conditioning systems, highlighting not just their impact on cabin comfort but also their critical function in battery thermal management.
“When it comes to EVs, air conditioning isn’t just about keeping the cabin cool,” Stewart explains. “It plays a key role in regulating battery temperature, which is essential for performance, safety and longevity.”
The course 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.
Available on Valeo Tech Academy, the new module forms part of a growing library of free and IMI-certified training. The platform covers a wide range of topics from traditional maintenance and repair to hybrid and electric vehicle systems, as well as advanced driver assistance systems (ADAS).
Courses feature interactive, gamified content designed to make learning more engaging and effective, with pre- and post-assessments enabling technicians to monitor their progress and measure skill development.
Technicians can also find additional resources on the Valeo Tech Assist website, including fitting guides and technical bulletins – all available at no cost. Plus, those fitting Valeo products can scan barcodes to earn rewards through the Valeo Specialist Club, redeemable in the Valeo online shop.
