Costs to Replace an EV Battery and How to Avoid It

When it comes to electric and plug-in hybrid vehicles, many buyers wonder how long it will be before the battery needs to be replaced. so how much will it cost to replace that battery?

We know that batteries degrade as a result of a phenomenon called “natural aging.” Like human aging, calendar aging is a baseline of decline over time. Other types of battery performance loss are related to use and exposure. we wrote a whole article on battery degradation.

I go through the details and cite examples for each ev model, but here’s a quick overview of the vehicles I cover in this article.

how much does it cost to replace an ev battery?

the replacement ranges from $0 to $20,000 depending on dozens of factors. If a battery is within the manufacturer’s warranty, usually 8 years and 100,000 miles, then you should get a replacement battery at no additional cost. but what if it’s out of warranty?

Battery replacements are still rare, so up-to-date cost data can be difficult to find. As battery prices continue to drop, the price you would pay today is different than the price you would pay next year or 5 years from now. In 2019, the Mack Institute for Innovation Management at the Wharton School of Business aggregated data found in academia, news, search engines, experts within the industry, and public statements from manufacturers.

found a 16% decrease in the cost of battery packs between 2007 and 2019. The authors calculated the average cost of battery packs in 2019 to be $161/kWh. With that estimate, in 2019, the cost of a 100 kWh out-of-warranty battery, as is common in Tesla long-range vehicles, would be at least $16,100 before labor, taxes, etc. if the trend in battery price reduction remains constant, then by 2025 the price in 2019$ should be ~$56/kwh, or $5600 to replace a 100kwh battery. that’s a big change in total cost.

how does this compare to other battery cost aggregators?

according to an april 2019 report from the international council on clean transport (icct), the projected cost for 2025 should be $120/kwh to $135/kwh. This is less generous than Wharton’s analysis, which suggests that by 2025 an out-of-warranty 100 kWh battery replacement may cost as much as $13,500. The ICCT report notes that battery cost forecasting has consistently underestimated actual battery cost reduction. provide a caveat that if a slightly more optimistic analysis is done, costs at the battery pack level could be $89/kwh by 2025 and $56/kwh by 2030.

according to the latest forecast from bloomberg new energy finance (bnef), in December 2020 the average price of battery capacity was $137/kwh, with an average price expected to be close to $100/kwh for 2023, seven years ahead of Bloomberg nef models suggested in 2016. Cited in the 2019 icct report, bnef models estimate that by 2030, average battery pack tier costs will be $62/kwh. replacing a 100kwh pack can cost at least $6,200 by 2030.

in 2016, mckinsey reported the average price of battery packs to be ~$227/kwh, and projections estimated average prices for electric vehicle battery packs to be below $190/kwh by the end of 2020. those expectations were clearly exceeded, as evidenced by the 2020 bloomberg nef report just described.

real world replacement cost examples

The limitations of this analysis is that it does not include labor costs, tax policy, business models, and other externalities associated with replacing a battery. It does not cover business profits or margins or whether a car purchased in 2017 will benefit from reduced battery pack cost in 2030. In addition, this analysis does not consider the possibility of replacing only those parts of battery packs that have been damaged. damaged, which may be covered under warranty. furthermore, it is difficult to anticipate the development of third-party battery replacement services independent of the original manufacturers.

However, to take a look at some real-world examples of battery replacement costs ev drivers have experienced, I found some helpful examples. Overall, it doesn’t appear that EV owners are benefiting from Bloomberg’s reported average price of $137/kwh.

This is what I found in the following electric vehicles.

  • chevrolet bolt
  • chevrolet volt
