Electric vehicles (EVs) have been surrounded by myths and misconceptions since their rise in popularity. Two common concerns are the deterioration of EV batteries over time and the cost of replacing them. Let’s address these issues with the latest information and research to clear up any confusion.
EV Battery Deterioration
It’s true that EV batteries, like all batteries, do experience some degree of degradation over time. However, the extent of this degradation might not be as alarming as often portrayed. According to a 2019 study by Electric Autonomy, which tracked battery capacity deterioration across 21 EV models over five years, the average loss in battery capacity is about 2.3% per year. For a vehicle with an initial range of 480 kilometres, this translates to a loss of approximately 55 kilometres over five years, or about 11 kilometres per year.
Additionally, research from Recurrent Auto shows that most degradation occurs within the first 80,000 kilometres of ownership. The rate of deterioration is most significant in the first couple of years, then tends to level off. By the time an EV reaches around 13 years old, the battery is expected to retain approximately 70% of its original capacity, ensuring a practical range for daily city commutes and occasional road trips.
Manufacturers back this up with warranties, typically offering coverage for eight years or 160,000 kilometres. This warranty guarantees that if the battery’s capacity drops below 70% during this period, it will be replaced. Based on current data, it’s unlikely that an EV will reach such levels of degradation within this timeframe.
Cost of Battery Replacement
The cost of replacing an EV battery, while significant, is a topic of evolving discussion. Replacement costs can vary widely, generally falling between $8,000 and $20,000 depending on the battery size and complexity. However, this cost is decreasing over time as technology advances and economies of scale improve.
For comparison, the internal combustion engine (ICE) in conventional vehicles, often the most expensive component, can also incur high replacement costs. Considering the overall savings on maintenance and fuel costs with EVs, the total cost of ownership can be quite favourable.
