On average, current EV battery packs cost around $10,000 to $12,000.
If there were any doubts that electric mobility is becoming the new norm, PwC recently reported that global EV sales grew by 75% in Q3 2022 compared to the previous year.
While many drivers are considering buying an electric car, its hefty price tag is still one of the main barriers to EV adoption. By far the main component of that price is an EV’s battery. Despite a recent rise in battery costs, the overall trend this past decade has been one of considerable price reduction, and this is expected to continue over the coming years.
In this article, we deep-dive into the factors that determine an EV battery’s price, replacement costs, and what you can do to keep your car’s battery in good health so you can extend its lifespan as much as possible.
Nowadays, it’s not much of a surprise that batteries are expensive. But why exactly do they cost so much? Obviously, the materials used contribute to the price, but the story is slightly more complex than that. Let’s break down the factors that make up an EV battery’s cost.
Like the battery in your phone or laptop, an EV’s battery pack is mainly made of lithium – only on a much larger scale, with thousands of rechargeable interconnected lithium-ion cells.
Because it’s much bigger than the battery in your phone and designed specifically for high-intensity use, EV batteries are more resilient and longer lasting than most consumer electronics.
Creating an EV battery requires a range of materials and elements, many of which are rare or difficult to extract. Besides lithium, EV batteries commonly use metals like nickel, cobalt, manganese, and graphite, as well as steel or aluminum to enclose the battery pack.
The number of materials used and the difficulty in sourcing them can often drive up the cost of an EV battery significantly.
The challenge of finding materials for EV batteries is exacerbated by the explosive growth in demand for electric vehicles, which puts pressure on supply chains to deliver more and more resources.
Since the beginning of 2020, the automotive sector has struggled with ongoing shortages of computer chips, which continue to impact the cost of making an EV. On top of that, challenges in sourcing enough lithium have held back many EV companies and forced them to increase prices further.
All of these reasons have pushed lithium prices to an all-time high in 12 years, which translates to a rise in EV battery costs. And with global manufacturers investing more than $500 billion in electrifying their fleets, we might still see further price increases as carmakers compete for the available supply.
Manufacturing also contributes to the cost of an EV battery. Compared to other types of batteries, EV batteries have particularly high energy density – a measure of how much energy can be stored in a given weight. This is essential to maximize the power that can be stored while limiting the car’s weight and ensuring optimal range.
Achieving high energy density requires expertise which few countries and companies have. China currently produces about 70% of EV batteries, with the US, Japan, and Korea also holding an important share of the market.
Naturally, this concentrated know-how drives up battery prices, and while countries like the US and EU are trying to develop domestic production, China is likely to remain the leading EV battery supplier until at least 2030.
Given how much EV batteries cost in the first place, it shouldn’t come as a surprise that replacing the battery in an EV is a significant investment.
That said, having to replace an EV’s battery is extremely rare.
Currently, EV batteries are expected to last somewhere between 15 to 20 years or 100,000 to 200,000 miles depending on your driving behavior, which is far longer than the life expectancy of an average car.
In the unlikely case that you need to replace your car’s battery, it can cost anywhere from free to upwards of $20,000, depending on whether it’s under warranty or not.
How much a battery costs to replace also depends on the vehicle. While some models have easily accessible and standardized battery packs, others may be challenging to remove or use custom-made batteries, which can be more challenging to source.
Even if your battery does fail, most EV manufacturers offer at least an 8- 10 years warranty on the battery pack, meaning your vehicle is very likely to be covered for most of its life and won’t cost you anything to repair.
While EV batteries last a long time and benefit from extended warranties, as the saying goes, it’s better to be safe than sorry. So, instead of waiting for your battery to die, there are simple steps you can take to prolong its life and minimize aging.
For instance, batteries are placed under strain when charged fully or drained completely empty, so it’s recommended to keep your EV’s battery charge between 20 and 80 percent for everyday use. Similarly, charging your EV too often can also wear down the battery, so it’s advised to only charge as much as you need for your use.
