Well, if it carries on like this, then I'll be down to 80% of original capacity this time next year, and frankly that would be a big deal. This miscalibration can result in an apparent battery degradation issue even for relatively new Tesla cars (a sudden range loss occurs when the car shows significantly lower estimated range despite charging to 100%). Web However like the Model 3 Model S and Model X reports of unusual degradation or warrantied battery replacement on the Model Y are very very low. Tesla Model 3 Battery Capacity After 8,610 Miles : r/teslamotors. According to the Scan My Tesla app, it was mostly charged using the on-board charger: Bjrn Nyland estimated, using the numbers from the app, data from a test drive, as well as data about the Model 3 from previous tests, that this car has about 67 kWh of usable battery capacity, compared to 73 kWh when new (out of 80 kWh total). To put things in perspective, according to theUS Department of Transportation Federal Highway Administration, Americans drive an average of13,476miles a year. Your warranty doesn't have a degradation guarantee, so even if you can show it's shrunk bu 30% it's not a warranty matter. The second is that attempting to store too much energy in a battery, or extracting too much energy from a battery, damages the battery, which reduces its capacity in the future. We may earn a commission for purchases made through our links. Tesla model 3 reichweite erfahrung. Although, Tesla interestingly used to not clearly cover battery capacity degradation in its warranty until it launched Model 3. Copyright Digital and Analytical 2023. As well as managing charging it also works out the available amount of energy stored in the battery and in turn the number of miles that energy can drive the car for. If our car's battery continues to erode at this rate, it will qualify for replacement under Tesla's warranty. Engineers continue to improve the battery, improving its parameters. Battery degradation depends on various things, including battery age, use (number of cycles/mileage), temperatures, chemistry, use (fast charging), time of storage at high state-of-charge, and more.. What is the range of today's electric cars? When you access the website or use the Services, we may use cookies (or similar tracking technologies).

To give us an idea of the Model 3 Performance's battery degradation, Kyle Supercharged to 100 percent and performed the usual 70 MPH highway range test. If readings are however available at lower states of charge, the BMS will be able to know where both zero and 100% are more accurately. Is there a way to check if the battery somehow degraded or if there is something else throwing off the calculation? Battery range degradation graph - 22 MYLR. Does Mileage Impact EV Acceleration? The Tesla Battery Management System (BMS) is responsible for looking after the battery. Read on to learn about it. Sure, battery degradation may continueat200,000 miles but you'd be surprised how many epic Tesla road trips arestill being enjoyedby those high-mileage, all-electric road warriors out there. Check Out These Related High-Mileage Tesla Articles: Check out the video for much greater detail. How to use: Adjust parameters to match your situation (state, driving style, etc.) By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. As the BMS extrapolates through these readings it has, if there are few low down it will start to be cautious and assume a dropping capacity. Figure 2: Battery degradation comparison of the 2015 Tesla Model S (liquid cooling) vs. the 2015 Nissan Leaf (passive air cooling). Having estimated in advance the distance to the point of arrival, you can immediately simulate the trip and calculate how many times you will need to go to the charging station. Tall rear passengers may find the seats a little odd, as the battery makes the floor higher than expected. The car is 3 years old and covered 164,541 km (102,263 miles), which is quite a substantial distance. The Tesla Model 3 lost 44 km (9%) of range including the cold blue inactive portion of the battery, this range loss is calculated before the battery gets heated while being driven. It may not display this or other websites correctly. To address this, the battery benefits from a 100% charge. Moreover, EVs have long/high mileage warranties that cover the battery, electric motors, and related components. As said, the BMS needs a number of stable readings at different states of charge. That meansTeslas 100,000 120,000 mile warranty is plenty sufficient to cover 6-8 yearsfor most typical drivers out there. Parts Theft - No expensive catalytic converter to be stolen while the vehicle is parked. Writtenby:Iqtidar Ali. While this sounds easy, it is harder than you may imagine if the car is always being either driven or being charged. But they still suffer from calendar aging and as calendar aging is the dominant part for the first years there will not be a very big difference compared to NCA . The figures below are from various sources on the internet and are the theoretical limits, sometimes worked out by reverse engineering the battery management system and sometimes by tearing down the battery packs. We'll continue to watch this battery degradation trend and let you know where our pack ends up at the end of our 40,000-mile test. How does the weather affect the range of an electric car? The first models came with a battery with a useful capacity of 50 kWh, and today you can already find cars with a capacity of more than 100 kWh. If a car is typically recharged straight after a journey then the car will not provide a stable reading until the charging has finished. Higher-performance Tesla batteries have been listed online at hefty prices. It is, however, worth noting that the range displayed on the screen is unlikely to ever show the rated range given by Tesla when charged to 100%. We have created a Battery capacity calculator tool that can get information via the API that will calculate the battery capacity for you. Consider becoming a Supporting Member of Tesla Motors Club. If you suspect calibration rather than cell balancing to be the issue, e.g. How to use an EV network and stay polite? Once you've worked out the figure above, you can compare it to the usable capacity figures in the table below. Buying a Model 3, Model S or Model X?Get 1,000 miles of free Supercharging with our referral. I've watched a few videos by Bjrn Nyland on long-term degradation. Discuss Tesla's Model S, Model 3, Model X, Model Y, Cybertruck, Roadster and More. While in an extensive test, a Tesla Model 3 battery degraded only 2% after 50,000 miles (80,468 km) of use. Reports suggest there is an initial drop within the first few months and then the rate of degeneration tails off. If your car has collected much dust as mine has recently and its been a long time (or never) since youve done this, when using up that last bit of battery on the discharge part, stay close to a charging outlet and pay close attention to how the power output decreases as you approach single-digit SOC. This year, it updated stats from its Model S and Model X fleet, and it claims a battery capacity retention . We provide product listings on Amazon for which we will receive a small commission if you chose to buy. On the trip from Colorado through Wyoming and into Nebraska, there was a tailwind on the way out, which Kyle says was counteracted by headwinds on the return. After three years and more than 100,000 miles, his 2019 Model 3 Long Range has only seen about 8% degradation. In the latest video above, he gets into the EV's battery degradation or, in simpler terms, its total battery capacity loss since he took delivery. You should see after each cycle the range increase. For the Model 3 and to a lesser extent the Model Y, the batteries have gone through a number of iterations, for instance 3 different batteries have been used in the M3 SR+. This content is imported from poll. A common concern for Tesla owners is how to calculate the battery degradation or establish the health of the battery as it's not that easy. The AVG consumption, the Projected range and the Percent. All Tesla rights reserved. The Leaf has an average degradation rate of 4.2%, while the Model S is 2.3%. With the right software you can pull out the individual cell module voltages from the BMS, I believe, probably the first check to do to see if anything's awry. What does a lithium-ion battery consist of? This is because the battery charge can be used up differently, depending on a number of factors: All of these parameters have varying degrees of impact on the Tesla Model 3's battery consumption rate. Much like the little lithium-ion pack in your cellphone, the battery in an EV slowly loses its ability to store energy over time. The battery degradation is a real, physical process. It offers loads of insight, and he promises another video going into TeslaFi in much greater detail. Many folks are concerned about buying an EV not only due to range anxiety, but also for fear that they'll have to eventually replace its expensive battery pack. Every time I see people talk about battery degradation, they use a method that I believe is incorrect for measuring it. Take it on a long drive until the battery drops below 50%. After seeing this its quite questionable. Be mindful if you have the heating on, the car will still be taking current, but not for the purposes of charging the battery. It's normal for a new Tesla to lose some capacity in its first year. We provide product listings on Amazon for which we will receive a small commission if you chose to buy. There is no reliable way to measure this, short of discharging the battery to a particular state of charge (SoC) at a fixed discharge rate (because discharge rate has a big impact on losses) and fixed cell temperature (because temperature has a big impact) and then recharging the battery at a fixed rate (again because charge rate has a big impact on losses) and fixed cell temperature to another given SoC. Newer Tesla Model 3 Long Range electric vehicles equip an 82 kWh 350V lithium-ion battery pack. No data should be relied upon as being accurate and additional checks should be made if the information is material to any purchase or use of the car. They will certainly have more accurate access to numbers at module level and know how to interpret them to see if anything unusual is going on.
