How Long Do Electric Car Batteries Last?

Most owners of electric vehicles do not require extended warranties for their battery packs as these cars feature batteries that are protected against degradation in extreme temperatures, even under harsh circumstances like heat and cold. However, electric vehicle batteries do degrade over time due to multiple factors including battery chemistry, driving habits, and environmental conditions.

1. Degradation

EV battery degradation refers to the gradual decrease in energy capacity over time. It’s natural, just like any component that wears out over time. Most electric vehicles (EVs) come equipped with additional warranties covering their battery, such as those offered by Geotab telematics provider. Geotab reports that an average 60kWh EV battery degrades at 1.8% annually. An electric vehicle (EV) battery should last hundreds of thousands of miles with proper care and maintenance, however, its exact lifespan will depend on its make, model, and year of manufacture. Hotter climates tend to accelerate battery degradation more quickly.

2. Chargers

EV batteries can’t escape the normal wear and tear associated with driving an electric car, though. Driving style can affect battery health and performance as well; continuously demanding big bursts of acceleration could diminish battery capacity and lifespan over time. Driving style, climate, and Level 3 fast charging frequency all impact an electric vehicle’s battery’s longevity. Thankfully, most warranties cover these batteries to guarantee at least 80 percent of original capacity for eight years or 100,000 miles. Electric vehicles do not require regular oil changes, fuel filter replacements, or smog checks – in fact due to regenerative braking, they often last longer due to extended brake pad lifespan.

3. Temperature

As previously discussed, extreme temperatures can adversely impact the chemistry found within an electric vehicle’s battery that produces power. For instance, the scorching summer heat can damage these batteries significantly. Manufacturers are acutely aware of this problem and have designed systems to combat extreme temperature effects. For instance, most electric cars will reduce charging speeds if their battery becomes overheated. Even with all these precautions in place, however, EVs will eventually lose some range due to repeated discharge and recharge cycles reducing their maximum capacity over time – similar to what occurs with smartphones or laptops.

4. Environment

An electric vehicle’s battery can also be affected by its environment, with cold temperatures slowing charging rates and potentially shortening its lifespan depending on the manufacturer and car model. Every full charge and discharge cycle shorten a battery’s lifespan and decreases capacity; however, most users rarely completely drain their electric cars’ batteries, and many automakers limit maximum charges to protect battery health. EV batteries typically last 15-20 years and many can be recycled to recover valuable raw materials – making them more sustainable than their lead-acid counterparts found in gas cars.

5. Hybrids

Hybrid cars use electric car batteries to supplement or replace their gasoline engines, and hybrid car manufacturers in the US must guarantee them 100,000 miles or eight years of driving – this warranty extends when selling to new owners.  Proper maintenance extends the lifespan of hybrid vehicles well past their warranty period. You can keep battery health intact by following charging guidelines (parking in the shade and cooling before and after every charge) as well as driving it within specified temperature ranges.

6. Maintenance

Every electric vehicle battery comes with eight-year or 100,000-mile warranty protection; many automakers also include additional battery replacement coverage. Battery degradation is an unavoidable aspect of the electric driving experience, but steps can be taken to lessen its effect. For instance, parking under shaded areas and keeping your battery cool can extend its lifespan and extend battery performance. As such, it is not advised to keep an EV in its full or near-full charge state for extended periods as fully charging can strain its batteries and reduce their lifespan.

7. Safety

Even though there have been viral videos showing electric car accidents leading to explosions and fires, their batteries are far safer than gasoline-powered ones. All EVs adhere to stringent safety standards and feature an emergency disconnect switch designed to prevent them from exploding in an accident. Like mobile phone batteries, electric vehicle (EV) batteries go through cycles of discharging when driving and charging when plugged into an outlet; over time this erodes their capacity and decreases. Lithium-ion batteries offer more sustainability than gas-powered cars by being recyclable to recover raw materials and keep the vehicle warm in winter weather, thus decreasing range.

8. Insurance

At the core of every EV is an electric battery that converts chemical energy to electrical currents that power all aspects of its operation, including its motor. Many electric car manufacturers provide an eight-year or 100,000-mile battery warranty that protects against complete failure while guaranteeing it will retain a percentage of its original capacity over this timeframe. However, you can reduce battery degradation over time by parking in the shade and charging until at least 20% full – doing this puts less strain on the internal chemistry of your battery and could significantly extend its lifespan.

9. Cost

While lithium-ion batteries in smartphones or laptops wear down over time, those found in electric car battery packs often last much longer before needing replacement. Many EV models come equipped with an 8-year or 100,000-mile warranty on their battery packs for added peace of mind. EV battery packs are made up of expensive materials like lithium, cobalt, and manganese that may fluctuate based on global supply and demand fluctuations. Still, most EVs typically cost less to maintain and operate than comparable vehicles powered by traditional fuel, providing fleets an opportunity to lower emissions while simultaneously cutting costs through an EV conversion.
