How Long Tesla Batteries Last

How Long Tesla Batteries Last – How many miles or years does a Tesla battery last? It is difficult to give a definitive, fact-based answer to this question. Although the first electric cars have been around since the 1800s, modern electric cars have not been on the road or sold in large numbers long enough to prove themselves in the real world The first production electric car, the Tesla Model S, recently turned 10 years old.

The data is worse because the battery life of an electric vehicle is constantly moving. Over the past decade, many changes have occurred in battery chemistry, battery design, and battery management systems. Battery packs from a decade ago are very different from the ones found in today’s Tesla cars.

Despite these obstacles, we aim to give you an overview of the life and range of your Tesla battery. Since we can’t choose a short answer, here’s the long answer:

Prolong Tesla High Voltage Battery Life

Before we get into the numbers, it’s important to understand that it’s rare for an electric car battery to suddenly stop working. Instead, they slowly degrade over time, gradually storing less and less energy and thus reducing the electric vehicle’s range. This degradation is not linear. Batteries are quickly damaged at the beginning of their life and can lose about 5% of their energy capacity. After that, it goes into a period of continuous slow decline.

Why does this happen? When you drive an electric car, the positively charged lithium ions in the battery move from a part called the anode, through the electrolyte, to the cathode. When charged, they return to the anode. The simplest explanation for battery degradation is that during charging and discharging, some of the ions stick to the cathode or anode. Fewer free-moving ions means less energy to power the car. Also, as an electrolyte ages over time, it becomes less efficient at moving ions through it. This deterioration (sometimes called calendar age) is only a matter of time, regardless of how often you charge or drive your car.

Like any car company, Tesla designs its products and warranties so that the company doesn’t burn money replacing parts at its own expense. You might think that Tesla’s battery warranty is a worst-case scenario. If the battery doesn’t die the same day the warranty expires, when is the earliest to replace an expensive battery?

Until 2020, Tesla offered an eight-year, unlimited-mileage warranty on the Model S and Model X battery and drivetrains. The warranty on those vehicles has since been revised to eight years or 150,000 miles. Tesla’s cheaper models have a shorter range. The Model 3 RWD is covered by an 8-year or 100,000-mile warranty, while the Model 3 and Model Y Performance, Long Range AWD, and Standard AWD are covered by an 8-year or 120,000-mile warranty. The company specifies that its batteries will retain at least 70% of their original capacity (also known as 30% degradation) during the warranty period. In other words, while the Model Y’s 303-mile range performance can still pack enough energy to drive at least 212 EPA-rated miles on a full charge, it’s performing as expected

Tesla Research Group Shows That New Battery Could Last Up To 100 Years

According to Tesla’s 2021 Impact Report, its batteries are designed to extend the life of the vehicle, and the company estimates a range of about 200,000 miles in the United States and 150,000 miles in Europe. Tesla’s own data shows that Model S and X batteries retain an average of about 90% of their original capacity after 200,000 miles of use. Tesla CEO Elon Musk also said on Twitter that the battery packs in the Model 3 and Model Y are rated for 1,500 charge cycles, which means the typical range model can go about 300,000 miles, and the long-range models about 500,000. one thousand .

Until now, most Tesla vehicles sold in the US have used nickel-cobalt-aluminum (NCA) lithium-ion batteries, but the company recently began using lithium-iron phosphate (LFP) cells in the lower-end Model 3 models. These cells are less energy efficient than NCA cells, but should be more resistant to pollution. Tesla has also started using the new Nickel Cobalt Manganese (NCM) 4680 batteries in the standard Model Y AWD series produced at the Gigafactory in Texas. It may be more than a decade before we fully understand how these new cells work in the real world.

Tesla has sold more than 1 million vehicles, and there are several real-life examples of how owners have racked up a lot of miles. Twitter user gem8mingen drives a 2013 Tesla Model S P85 with over 1 million miles after the original battery was replaced at 280,000 miles.

Tesloop, a former California ride-hailing service, was one of the first companies to drive a 2016 Model X 90D over 300,000 miles in 2018. The electric SUV relies heavily on DC fast charging, which drains the battery faster, but the company only reports 12.6 percent battery discharge, with most of that occurring during the first nine months of use.

Here’s How Much It Costs To Replace A Tesla Battery

The Maiden Voyage blog shared one owner’s experience with a 2018 Tesla Model 3 Long Range RWD that experienced a 13.7% drop in performance at 200,000 miles. one

Reader Corey told us that his 2018 Model 3 Long Range passed the 100,000 mile mark in late June 2022 after losing about 7% of its power.

If you’re looking to buy a used Tesla, it’s a good idea to check the battery’s health. The easiest way to measure battery discharge is to charge the vehicle to 100% and then compare the displayed range to the EPA rated range. But there is a downside to this approach because Tesla can change the display area during a software update. For example, back in 2019, Tesla increased the range of the Model 3 Long Range RWD from 310 miles to 325 miles as the company made the engines more efficient through software updates. If someone today used the first 310 miles to determine battery life, the results would be incorrect.

Another easy way to check your battery is to charge your Tesla from 10% to full and look for the “+kWh” number in the upper left corner of the Model 3/Y or Model S/X home screen or combination of Tesla instruments. addition. Divide this number by 0.9 and compare the result to the factory-claimed capacity of the new battery. This method isn’t perfect either, but it should give you a good estimate of battery life.

Tesla Battery Replacement: Average Costs And What To Expect

In late 2022, Tesla released a battery health test that any owner can complete in service mode. To perform this procedure, the vehicle must be connected to a 240-volt level 2 charging station with a battery charge of 50% or less. The test can take up to 24 hours to complete, although starting with a lower value (eg 10% instead of 50%) can speed up the process.

To access service mode, go to your vehicle’s software page, press and hold the model logo for a few seconds, enter “Service” as the access code and press “Enable”. In the Service Mode menu, click Battery, then High Voltage, then Health Test. Then follow the on-screen instructions, hold the steering wheel, apply the brake, and hold the Tesla keycard in place on the center console until the screen reads “Gateway Status: Unlocked.” The suitability testing process can then begin.

The car makes strange noises when it drains the battery to 0% and then slowly charges it to 100%. After the test is complete, the Battery HV column will show the percentage of battery health. Note that this number shows battery condition, not battery capacity, and we don’t know what features Tesla took into account when creating the final product. For example, we recently ran a battery health check on a Model 3 and the car retained 93% of its energy capacity (69 kWh from the original 74 kWh), giving it an 86% battery health rating.

We do not recommend checking the battery status frequently. The process of discharging to zero and fully charging increases the wear and tear on the battery, and Tesla does not guarantee that the battery will be damaged unless the resource is below 70%. As a car owner, you can get your car checked once a year using one of the above methods, but don’t lose sleep over it. Some battery contamination is inevitable and normal.

How Long Does A Tesla Battery Last?

If your Tesla needs a new out-of-warranty battery, you can expect to pay between $10,000 and $20,000 depending on the model, local labor costs and taxes Tesla prefers to use refurbished battery packs to keep replacement prices lower than buy new ones. It also ensures that the packet capacity is equal to or greater than the original packet
