The independent aftermarket faces a growing wave of electrified service work, with MAHLE projecting 34 million high-voltage batteries in operation across Europe by 2030 and around 1.3 million requiring annual maintenance. According to MAHLE Aftermarket, the shift to hybrid and electric vehicle servicing demands a rethink of workshop skills, equipment, and service capability — and businesses that fail to adapt risk being left behind. With battery lifespans typically running 10 to 14 years, the company says independent workshops are set to inherit a significant share of this work as vehicles move out of warranty.
Highlights
- MAHLE projects 34 million high-voltage batteries in operation across Europe by 2030, with roughly 1.3 million requiring annual maintenance.
- The company’s TechPRO 2 diagnostic platform generates CARA-certified State of Health reports for EV batteries via its E-Scan function.
- MAHLE reports its TechPRO Digital ADAS 2.0 system cuts calibration time by up to 80% through self-adaptive calibration.
- Battery lifespans of 10 to 14 years mean out-of-warranty EVs are flowing steadily toward independent workshops.
Why Is Battery Diagnostics Becoming a Core Workshop Service?
The traditional workshop model built around mechanical repair is giving way to an environment centered on diagnostics, software, and high-voltage systems. MAHLE notes the industry has already moved from purely mechanical work to on-board diagnostics and high-voltage technology, a shift that continues to accelerate.
While EVs are often perceived as requiring less maintenance, the company argues the long-term servicing picture tells a different story. Battery diagnostics is becoming a core service area, with technologies such as E-Scan and E-Health enabling technicians to assess battery condition and performance and predict remaining lifespan. The TechPRO 2 diagnostic platform supports this work with E-Scan functionality capable of generating CARA-certified State of Health reports — a capability that echoes the high-voltage battery repair programs automakers have been building on the franchised side.
Thermal Management as a Revenue Opportunity
MAHLE identifies thermal management as one of the most critical and potentially lucrative service areas in hybrid and electric vehicles. As electrification increases, demand grows for cooling systems that manage batteries, power electronics, and drivetrains, driven by both customer comfort expectations and the technical demands of modern vehicles.
This opens new service areas for workshops, the company says, including:
- Battery cooling system maintenance — MAHLE’s E-Care system manages draining, filling, and pressure testing of battery cooling systems, with coolant quality and system integrity playing a critical role in battery performance and longevity.
- Air conditioning and heat pump servicing — the ArcticPRO ACX 380 and ACX 480 units provide a fully automated recovery, vacuum, and refill process, which the company says reduces labor time, specialist skill requirements, and potential for errors. Integrated circuits for POE oil and UV dye support both hybrid/EV and internal combustion vehicles.
ADAS Calibration Demand
Growing vehicle complexity is also driving demand for advanced driver assistance system calibrations. MAHLE’s TechPRO Digital ADAS 2.0 uses self-adaptive calibration that eliminates the need to physically move the vehicle and target boards, which the company reports cuts calibration time by up to 80% while removing the need for a dedicated calibration bay.
Skills, Safety, and Infrastructure
Unlocking these opportunities requires investment in people as well as equipment. The modern technician is evolving into a high-voltage, IT-literate specialist, with formal qualifications now essential for working safely on hybrid and EV systems, and structured certification levels reflecting the safety considerations involved.
“The workshop of the future is already here, but there’s still a gap between where some workshops are today and where they need to be. Electrification isn’t something that’s coming, it’s already in the workshop. The businesses that invest in training, equipment and service capability today will be the ones that benefit as EV and hybrid demand continues to grow,” said Andy Lees, Head of Western Europe at MAHLE Aftermarket UK.
Electrification is also reshaping the workshop environment itself, from insulated tools and personal protective equipment to EV-compatible lifting platforms and dedicated high-voltage work areas. Alongside the technical changes, digitalization — paperless processes, automated check-in, digital inspections, and video health checks — is streamlining operations and helping workshops identify additional work.
MAHLE notes that while some traditional service areas may decline, they are being replaced by higher-value technical work, with EV servicing able to command higher labor rates that reflect the expertise and investment required.
“Workshops don’t need to do everything overnight, but they do need a plan. The shift to hybrid and EV servicing is only going in one direction, and those who take steps now will be in the strongest position to grow as the market evolves,” Lees said.
