A Shift That's Already Underway

Electric vehicles are no longer a niche segment. As EV sales continue to grow across the globe, the auto repair and mechanical services industry is navigating one of its most significant transitions in a century. The shift from internal combustion engines (ICE) to electric drivetrains doesn't just change what's under the bonnet — it changes almost everything about how vehicles are serviced, diagnosed, and repaired.

What EVs Don't Need (And Why That Matters)

The mechanical simplicity of an electric drivetrain eliminates a substantial portion of traditional service work. An EV has no:

  • Engine oil or filter
  • Timing belt or chain
  • Spark plugs or ignition coils
  • Fuel injectors or carburettors
  • Exhaust system or catalytic converter
  • Transmission fluid (most EVs use a single-speed reduction gear)
  • Coolant system for a combustion engine (though thermal management of the battery pack does require maintenance)

For workshops that rely heavily on routine service intervals — oil changes, timing belt replacements, exhaust repairs — the growing EV parc represents a genuine revenue challenge. Industry analysts widely project that service revenue per vehicle will decline as EVs become a larger share of the fleet.

What EVs Do Need Serviced

EVs are not maintenance-free. They still require:

  • Tyre rotation and replacement — and often more frequently, as EVs are typically heavier and have higher instant torque that accelerates tyre wear.
  • Brake inspection — though regenerative braking significantly reduces pad and rotor wear compared to ICE vehicles.
  • Cabin air filters — the same as any vehicle.
  • Battery thermal management fluid — coolant for the battery pack requires periodic inspection and eventual replacement.
  • 12V auxiliary battery — EVs still use a conventional 12V battery to run accessories and control systems, and it needs replacement like any other.
  • Software updates and diagnostics — EV systems are heavily software-driven, and electronic fault diagnosis is a growing area of specialisation.
  • High-voltage battery servicing — over time, battery pack degradation, cell replacement, and charging system repairs will become more common as first-generation EVs age.

New Skills and Certifications Required

Working on high-voltage systems (typically 400V–800V in modern EVs) is fundamentally different — and significantly more dangerous — than working on conventional 12V vehicle systems. High-voltage work requires:

  • Formal training and certification in high-voltage electrical safety.
  • Specialist insulated tools and personal protective equipment (PPE).
  • Procedures for safely isolating ("making safe") the high-voltage system before any work begins.
  • Updated workshop equipment, including specialised battery diagnostic tools.

Workshops that invest in EV training and equipment now are positioning themselves well for a fleet that will only grow. Those that don't may find an increasing portion of their potential customer base referring to the dealership or a specialist EV workshop.

The Opportunity in Battery Technology

As the first wave of EVs ages past the 8–10 year mark, battery degradation will become an increasingly common issue for owners. Battery pack replacement is currently very expensive, which is driving interest in:

  • Battery cell replacement and refurbishment (rather than whole-pack replacement)
  • Third-party battery suppliers offering more affordable alternatives to OEM packs
  • Battery health diagnostic services to assess remaining useful life

This emerging segment represents a significant opportunity for forward-thinking independent workshops willing to develop the expertise.

Hybrid Vehicles: The Bridge Technology

It's worth noting that hybrid vehicles — which combine an ICE with an electric motor and a smaller battery pack — still require most traditional service work. Hybrids are currently growing faster than pure EVs in many markets and represent a manageable transition for workshops: the high-voltage systems are lower voltage and less complex than full EVs, while the combustion engine side remains familiar.

Looking Ahead

The auto repair industry has always adapted to new technology — from carburettors to fuel injection, from cable-operated systems to drive-by-wire. The EV transition is larger in scale, but the principle is the same: the shops that embrace training, invest in equipment, and build expertise in emerging vehicle technology will continue to thrive.

For car owners, the practical takeaway is to seek out workshops that have invested in EV and hybrid capability — and to understand that while your EV may need less routine maintenance, the repairs and diagnostics it does require are increasingly specialised.
