EV Myths, Debunked

Evidence-based answers to the top 10 EV myths Australians ask about — cost, batteries, charging, range, safety, lifetime emissions, the grid, affordability, towing and servicing. Every answer cites primary sources you can verify.

EV batteries die after a few years and cost $20,000+ to replace

The reality

EV batteries are warranted far longer than the typical Australian ownership period. The industry standard is 8 years or 160,000 km, with most manufacturers also guaranteeing the battery will retain at least 70% of its original capacity over that window — Hyundai, Kia, BYD, MG, Tesla and Polestar all publish warranties on this scale, and several go further (Lexus offers 10 years / 1 million km on the RZ).

Real-world data from large fleets is even more reassuring. Geotab's analysis of more than 6,000 EVs found average battery degradation of around 1.8% per year; Tesla's 2024 Impact Report shows Model 3 and Model Y batteries retain 88% capacity after 200,000 miles (320,000 km). After 10 years on the road, most EVs still have well over 80% of their original range.

Replacement is also no longer the $20,000-plus catastrophe of earlier-generation EVs. Battery pack costs have dropped roughly 90% since 2010 (BloombergNEF) and most Australian-market EVs now have replacement quotes in the $7,000–$15,000 range — often less than the cost of a major engine rebuild on a comparable petrol car.
