How much does an electric car battery weigh? Electric vehicles (EVs) are growing in popularity, and sales in 2022 hit a new record of 200,000 sold in three months. With the growing interest in EVs, it’s expected that you may want to ask about a few features – which is where Hertz is here to help.
In this guide, we’re going to answer some questions about one of the most important parts of an EV: its battery. From how much it costs to how long its charge lasts, we want you to feel confident that you know the important aspects of an electric car’s battery.
How much does an electric car battery weigh?
Current electric car batteries have an average weight of around 1,000 lbs, but they will vary depending on the vehicle – some have much heavier batteries while smaller vehicles may have lighter ones.
For example, Tesla is one of the top EVs on the market, holding 66% of the market share. Their batteries can take you over 370 miles on a single charge, so it should come as no surprise that a Tesla battery is estimated to weigh up to a staggering 1,836 lbs. By comparison, the smaller vehicles can have batteries weighing well under 1000 lbs – over half the weight of a Tesla battery.
Do EV batteries weigh more than engines?
Yes, the batteries used in electric cars weigh more than traditional gas-powered vehicles. Despite internal combustion engines having around 2,000 parts in their powertrain, an EV’s battery nonetheless weighs a lot more.
The Nissan Leaf is one of the lightest electric vehicles weighing 3,516 to 3,934 lbs, while the Mercedes EQS is one of the heaviest at 5,467 to 6,493 lbs. To put this into perspective, a gas-powered Mercedes SUV with an internal combustion engine weighs slightly less, between 3,487 to 5,927 lbs. While a gas-powered Ford Focus will weigh between 2,935 and 3,434 pounds.
Based on these examples, EVs can weigh in the region of 15-20% more than their gas-powered counterparts.
How much is an electric car battery?
How much an electric car battery costs comes down to whether it’s replaced or repaired. According to research, an EV battery costs around $135 per kilowatt-hour. As an example, the Kia EV6’s 77.4 kWh battery will set you back $10,449.
By comparison, a Tesla Model 3 battery can cost around $16,550 for a replacement. However, remanufactured batteries can cost significantly less, between $9,000-$10,000, saving you money.
All cars need to be maintained and have regular trips to the auto mechanic to ensure they’re running correctly – and EVs aren’t exempt from this.
What determines the weight of electric car batteries?
Despite looking like a single unit, EV batteries are actually made of thousands of smaller cells connected together to form a large battery pack. By far the most popular battery chemistry used for EVs is lithium-ion, thanks to its cost efficiency and high energy density, offering the most optimal trade-off between energy storage capacity and price.
So what actually makes up an EV battery’s weight? On average, about 60 to 75 percent of a battery’s total weight comes from the cells and the materials they contain, while the remaining 25 to 40 percent is made up of the battery’s metal casing, cables, and thermal and battery management systems (TMS and BMS).
Besides lithium, EV batteries also contain many other minerals, such as cobalt and manganese. A typical EV battery has about 8 kilograms of lithium, 14 kilograms of cobalt, and 20 kilograms of manganese, although this can often be much more depending on the battery size – a Tesla Model S’ battery, for example, contains around 62.6 kg (138 pounds) of lithium.
How long does an EV battery last?
EV batteries are currently projected to last between 15-20 years or 100,000-200,000 miles. With US car owners keeping their cars for longer – around 12 years in fact – that 15-year replacement age could come down to you or the next owner. Keep up with the recommended maintenance to keep the battery and vehicle in the best condition possible.
How long does an electric car battery last per charge?
On a single charge, you can expect to reach an average of 250 miles. However, this can differ between models, with Tesla and Mercedes, for example, offering much longer ranges on a single charge.
The Tesla Model S can achieve a range of 405 miles on a single charge, so if you plan to drive an EV in an area where there’s plenty of charging infrastructure, there’ll be no need for you to experience range anxiety.
How often do EVs and batteries need servicing?
While EVs need servicing less often than gas-powered vehicles, they still need some attention to ensure they keep running efficiently and effectively. Each vehicle manufacturer will have a recommended maintenance schedule, which could be annually or after a set number of miles, whichever comes first. As an example:
- Tesla Model 3 is recommended every two years or 25,000 miles
- Nissan Leaf is annually or every 18,000 miles
- BMW i3 operates a condition-based servicing (where the car’s computer will monitor the vehicle and if it notices something needs checking, it will notify you automatically.
Can a bad car battery cause electrical problems?
Yes, a faulty car battery can cause electrical problems. A bad battery can cause the vehicle’s systems to malfunction and for some elements to not work properly, such as the stereo, air conditioning and other features like lights. Worse, the vehicle may struggle to start in the first place and may not hold charge for very long.
EV batteries are the heart of the vehicle. Maintaining them can help ensure your vehicle runs smoothly and efficiently for years to come.
Are electric cars heavier than gas cars?
If there’s such a difference between EV and conventional car batteries, do EVs weigh more overall as well? The answer is usually yes; EVs tend to be heavier than combustion engine cars, largely because of their heavy battery.
That said, the difference isn’t as straightforward as you might think.
While EV batteries are heavier, their motors are much smaller and lighter than an internal combustion engine.
To further make up for the additional weight that the EV battery brings, EVs replace traditional components with lightweight materials. High-strength steel, magnesium alloys, aluminum alloys, carbon fiber and polymer composites can allow the gross weight to be reduced up to 50 percent and reduce the vehicle’s fuel consumption, making it more efficient.
How much does a Tesla electric battery weigh?
Here are some examples of popular EV models’ battery weight: A Tesla Model S has a roughly 544 kg (1,200 pound) battery. A Tesla Model Y has a 771 kg (1,700 pound) battery. By contrast, a Nissan Leaf has an average battery weight of just 303 kg (668 pounds).
Are electric car batteries heavier than engines?
Electric vehicles can be anywhere from hundreds to thousands of pounds heavier than similarly sized gas vehicles because EV batteries are so much heavier than engines. For example, the 2023 GMC Hummer EV, a full-size pickup, weighs more than 9,000 pounds, sporting a 2,900-pound battery.
How heavy is the lithium battery in a Tesla?
A typical EV battery has about 8 kilograms of lithium, 14 kilograms of cobalt, and 20 kilograms of manganese, although this can often be much more depending on the battery size – a Tesla Model S’ battery, for example, contains around 62.6 kg (138 pounds) of lithium.
