How Often Do Electric Car Batteries Need To Be Replaced


What Happens To Electric Car Batteries After They Need To Be Replaced

How much does it cost to replace the battery in an electric car?

One of the questions about electric cars is what happens to the batteries when they are replaced. This is a valid question since batteries are one of the more expensive parts of an electric car.

Most people assume that the batteries will just be recycled, but thats not always the case. Often, the batteries are reused. This is done by either selling them to companies that use them for backup power or installing them in other electric cars.

There are also cases where the batteries are recycled. This is done by breaking down the battery into its parts. For example, lead and acid are separated and sold to companies that use them for other purposes. The plastic and metal are also recycled.

So, what happens to electric car batteries after they need to be replaced? In most cases, they are reused or recycled. This helps keep the cost of electric cars down and ensures that these batteries dont end up in landfills.

Electric Car Battery Replacement Cost

When it comes to replacing an electric vehicle battery, you need not be too concerned as many manufacturers provide a warranty of up to 8 years or 100,000 miles. Meaning that even if you did need to replace it in an unfortunate event that something did go wrong, then it could well be covered under this warranty. Remember to always check the type of warranty offered by your chosen electric car manufacturer.

Also, the cost of batteries fell about 80% between 2010 and 2016 according to McKinsey, from $1000 to $227/kWh. Therefore, a new 40kWh battery in 2016 would have cost just shy of £10,000. Some predictions estimate that prices are set to fall below $100/kWh by 2030, around the same time as the government are aiming for 50% of all new vehicles sold in the UK will be electric.

What It Takes To Replace An Ev Battery

If you think swapping out the battery in your EV is as easy as it is for handheld tech, think again. Depending on the vehicle make and model, its expensive and not always possible. The good news is that even older EV models dont require battery replacements as todays batteries can last for hundreds of thousands of miles.

But lets say you want to replace and upgrade your current battery for one that has more power . That might or might not be doable.

If you drive a Chevrolet Bolt EV, for example, a new battery pack will set you back more than $15,000 . For example, if your current EV has a 7.2kWh charging limit, and youd like to upgrade it to a 11kWh, eh, sorry. Thats not possible for most EVs on the market. Thats because the upgrade is a change in hardware, not just software.

Teslas are a bit of a different story, however. Many of that carmakers battery packs are one size, so owners can pay for a more robust battery if they choose. When buying an EV, be sure you carefully consider your potential battery needs.


An EV battery is essentially a group of smaller battery modules linked together. The end result is a battery that is typically very large . If a battery fails, its likely the entire thing will need to be replaced rather than one section of it.

Can You Repair An Electric Car Battery

Yes! We might think of the battery pack as a single part, but actually it can be broken down into three different levels: cells, modules, and packs.

To illustrate, a BMW i3 has 96 battery cells. 12 cells are combined into a single module, and 8 modules combine to make a single battery pack.

Often, only one module is defective and not the whole battery. For instance, corrosion around the battery sensors may signal an error to the battery management system, which stops the vehicle from functioning.

Because of this modular design, its fairly easy to isolate if a certain module is underperforming, and then replace it if necessary.

Another favorite anti-EV argument is that recycling Li-ion batteries is difficult, expensive or even flat-out impossible. However that is not the case.Recycling International reports that some 97,000 tons of Li-ion batteries were recycled in 2018, and over 1 GWh worth are currently serving in second-life applications.

Electric Car Battery Lithium

A Lithium-ion battery is a type of rechargeable battery used in electric vehicles and a number of portable electronics. They have a higher energy density than typical lead-acid or nickel-cadmium rechargeable batteries. This means that battery manufacturers can save space, reducing the overall size of the battery pack.

Lithium is also the lightest of all metals. However, lithium-ion batteries contain no lithium metal, they contain ions. For those wondering what an ion is, an ion is a an atom or molecule with an electric charge caused by the loss or gain of one or more electrons.

Lithium-ion batteries are also safer than many alternatives and battery manufacturers have to ensure that safety measures are in place to protect consumers in the unlikely event of a battery failure. For instance, manufacturers equip electric vehicles with charging safeguards to protect the batteries during repeated rapid charging sessions in a short period of time.

Ev Batteries: The Basics

Electric cars are powered by rechargeable lithium-ion batteries, which are more energy dense than the lead-acid batteries found in internal combustion engines or rechargeable nickel-cadmium batteries found in some hybrids. A lithium-ion batterys high energy density means it produces more power for its size, making it ideal for an electric car.

Because EVs are powered by the battery alone, they are far more simple and efficient than ICE vehicles. As lithium-ion batteries have decreased in cost by 97% over the last 30 years, experts believe that EVs will soon be as cheap to produce as ICE vehicles.

Do Electric Cars Lose Charge When Parked

Yes. Electronic components and functions are always switched on in the background, even when the cars engine is off.

Depending on the brand, an EV loses between 1% and 2% of charge a day when parked.

You can minimize loss of charge by activating power-saving mode and turning off unnecessary electronic functions when the car is off.

Internal combustion engined cars are powered by gasoline, while EVs are powered by a battery pack driving one or more electric motors. The batteries that power electric cars are rechargeable lithium-ion batteries, which is the same type of battery found in cell phones and other consumer electronics. Lithium-ion batteries have a higher energy density than lead-acid or nickel-cadmium rechargeable batteries, which means they dont take up as much space while providing an equivalent level of power. A vehicles battery capacity is measured in kilowatt hours , so a vehicle with a higher kWh rating means it has more range.

Evs Have A Longer Lifespan Than Gasoline Cars

Electric vehicles have much longer battery life than gasoline vehicles. An EV batterys life expectancy within the vehicle ranges between 15 and 20 years, and the battery lasts another 20 years after that. We expect battery life to increase as technology improves and batteries become less expensive, smaller, and lighter. Although battery life varies depending on the model, EV batteries should be replaced after 10 to 20 years of use however, batteries have at least 8 years of warranty coverage.

How Much Does It Cost To Replace An Electric Battery

The average cost of an EV battery in 2021 was approximately £87 per kWh. That would put the cost of a new Tesla Model S battery alone at close to £8,870, before you factor in what it would theoretically cost to remove and replace the old one. Its an eye-watering sum, and one which would probably leave you wondering whether or not you should just buy a new car, or avoid electric cars entirely.

Thankfully, as well see below, electric cars are covered by fairly generous warranties. Whats more, if you do need an out-of-warranty replacement, new EV batteries are becoming increasingly cheaper!

Do Electric Vehicle Batteries Have To Be Replaced After A Few Years

Weve already talked about the many environmental and financial benefits of buying an electric car. From national and regional incentives and bonuses, to fuel cost savings, to zero maintenance costs. But theres still a fear, which soon become objections from sceptics and detractors of electric mobility, and thats the cost of replacing the batteries. Theres a misconception that makes people think that electric vehicle batteries need to be replaced after a few years, and that the cost of doing this will cancel out any financial advantages gained over the years. The phrase you see most often is, after a few years you have to change the batteries, which costs you tens of thousands of euros. But is it really true that electric vehicle batteries lose efficiency and must be replaced after a few years, at great cost? Well give you a reply straight away: no, its not true, the batteries are made to last years longer than the average life of an electric car.

For example, on a Tesla Model 3 Long Range / Performance, the warranty period is 8 years or 192,000 km, whichever comes first. Further on in the warranty terms, youll find information on charge retention, which in this example is with minimum 70% retention of battery capacity over the warranty period. This means that if, in the 8 years, or 192,000 km, the cars battery should break or not charge beyond 70%, the battery will be replaced free-of-charge, under the warranty.

Does Ev Charging Affect The Battery Life

In short, yes. Charging a battery does have an effect on your vehicles battery life.

One of the innovations that led to the rise of electric vehicles over the past decade is Lithium-ion batteries. Traditionally, most vehicle batteries were made from lead-acid and only had to start a vehicles motor with a short surge of power which would then be recharged as the vehicle drove by an on-board alternator. However, they were not ideal for discharging more than a few percent of their power and are often referred to as SLI batteries .

Comparatively, lithium-ion batteries are designed to handle a much higher density of energy. Both your cell phone and your laptop use lithium-ion batteries and much like the advancement in the technology of both over the past two decades, lithium-ion batteries have increased the potential to use electricity in vehicles. And these advances are only tipped to continue.

However, while an EVs battery will lose its ability to fully charge over time, it is unlikely that it will stop altogether. There are a few best practices that you can do to extend the life of your EVs battery.

Will Ev Batteries Be Recycled At The End Of Their Working Life

What they DON’T tell you about electric car batteries

Yes, when EV batteries reach the end of their working life, they will be recycled. In the US, when the typical 8- to 10-year battery warranty has expired, most EV providers can reuse the batteries for a second or third time. As electric cars take pole position on our roads reducing greenhouse gas emissions and noise pollution compared to cars powered by fossil fuels the race is on to find ever better recycling methods to unlock their full green potential.

It makes neither economic nor environmental sense for EV batteries to be dumped in landfill it just wont happen.

The active battery recycling market is in its infancy, as car batteries are so reliable and long-lived, explains Graeme. But we can expect to see huge growth in recycling technologies. It makes neither economic nor environmental sense for EV batteries to be dumped in landfill it just wont happen.

The current methods of smelting and leaching will be finessed in coming years, as will the battery designs to optimise the separation and recycling process of end-of-life batteries. In the UK, the Office for Zero Emission Vehicles has launched a £7million competition for on-vehicle solutions that address challenges associated with the transition to zero emission vehicles, including improving sustainability.

Straubel told Wired: With all these batteries in circulation, it just seems super obvious that eventually we’re going to build a remanufacturing ecosystem.

Ev Batteries Require Less Maintenance

The battery, as well as many other components of an electric vehicle, require far less maintenance than their gasoline counterparts. As there are far fewer moving parts in electric motors compared to ICE enginesover two dozen fewer automotive componentsthere are fewer parts that could eventually fail or need replacing.

Plus, with fewer fluids, such as engine oil, as well as regenerative braking technology reducing brake wear, there is simply less which EV drivers have to worry about.

This fact alone has got dealers and mechanics worried about shrinking margins on EVs. Servicing and maintenance provide almost half of the average dealerships income and EVs are also expected to outlive gas vehicles, so many of their clients wont be upgrading them as often. However, whilst some are worried, Lawrence Burns, the ex-vice president of R& D at General Motors Co says that fundamentally, this is just a better way to design and engineer a car.

What Is The Life Expectancy Of An Electric Car

The battery packs have hundreds of gently topped-up cells inside, so they should have the capacity to charge and discharge from 100,000 to 200,000 miles. Electric cars have an extended warranty of eight years or 100,000 miles, as manufacturers are confident that the batterys road use is consistent.

It is critical for EV drivers to be familiar with a few basic concepts, such as how to care for their vehicles and the types of electric vehicles. Internal combustion engines produce gasoline that can travel more than 100,000 miles if properly cared for. According to the International Energy Agencys Global Electric Vehicle Outlook 2021, a new record 3 million new electric vehicles will be sold in 2020. Lithium-ion batteries are more energy-dense than lead-acid batteries, which are typically used to charge electric vehicles. When a battery degrades, it is used to maintain the vehicles range for the next few years. Understanding the charging process is critical to ensuring that the battery lasts as long as possible. When it is charging, you should keep it at a rate of 20% to 80%. It is preferable to charge your battery between 25% and 75% if you are away from it, rather than leaving it empty or completely charged. In the United States, all electric vehicles have a warranty that covers the battery for at least eight years.

How Much Does An Electric Car Battery Cost

The aforementioned fears are understandable: the battery pack of an EV is by far the most expensive part of the vehicle and can cost $5,000 on average and even as much as $15,000 per battery in some cases.

Its important to note here that battery prices have fallen dramatically over the past decade. For example, the average price of a kilowatt-hourthe standard measure of a batterys pricedropped from $1,160 per kWh in 2010 to just $128 today.

That price is expected to fall to stabilize at $90 per kWh by 2031 universally considered the point that EVs will cost as much as gasoline cars to manufacture.

The majority of manufacturers give between five to ten years warranty on their batteries or up to 100,000 kms .

Batteries are designed not to die fully, but slowly lose charging capacity over time. This depletion happens gradually with many reporting the loss of a few percentage points over the several years. To put this into perspective, according to Plug In America, a Tesla Model Ss battery only loses five percent of its original capacity over the first 80,000 km .

However, as with many components of older vehicles, the battery will eventually begin to degrade. To measure this, when looking at the average decline across all vehicles, the loss is arguably minor, at 2.3 percent per year. This means that if you purchase an EV today with a 240 km range, youll have only lost about 27 km of accessible range after five years.
