Electric vehicle ownership is growing in Perth, and with it comes a common question: what does an EV actually need for servicing, and who can do it? The good news is that EVs have significantly lower servicing requirements than petrol vehicles — but they still need attention.
What EVs Don't Need (That Petrol Cars Do)
- Engine oil and oil filter changes — no combustion engine
- Spark plugs
- Timing belt or chain
- Fuel filter
- Transmission fluid (for most EVs with single-speed transmissions)
- Exhaust system servicing
What EVs Do Need
- Tyre rotation and replacement — EVs are heavier than equivalent petrol cars, accelerating tyre wear
- Brake inspection — EVs use regenerative braking extensively, so brake pads last longer, but still require periodic inspection
- Cabin air filter replacement — same as any vehicle
- Coolant check — EV battery thermal management systems use coolant
- Windscreen wiper replacement
- 12V auxiliary battery — EVs have a small 12V battery separate from the traction battery that needs periodic replacement
- Software updates — often done over-the-air, but some require workshop visits
Battery Maintenance
The high-voltage traction battery doesn't require routine service, but there are practices that protect its longevity:
- Avoid regularly charging to 100% — most manufacturers recommend 80% for daily use
- Avoid regularly depleting to 0%
- Use DC fast charging occasionally but not exclusively — repeated fast charging accelerates degradation
- In Perth's heat, keep the vehicle plugged in when possible — thermal management works better when connected to power
Who Can Service an EV in Perth?
High-voltage battery and electrical work requires EV-specific training. For routine maintenance (tyres, brakes, cabin filters, 12V battery), most qualified mechanics can perform the work. For high-voltage systems, seek a mechanic with certified EV training. Perth Mechanic can connect you with mechanics who work on EVs — specify your vehicle make and model when requesting a quote.
EV Servicing Costs in Perth
- Annual inspection / service: $100–$250 (significantly less than petrol equivalents)
- Tyre set: similar to petrol car ($400–$1,200 depending on size)
- 12V battery replacement: $150–$300
- Brake inspection: $80–$150
