It does this by using an algorithm that adapts over time, constantly updating itself based on data points it collects from stable battery readings. The use of cookies is a standard industry-wide practice. TeslaFi. TeslaFi's battery-tracking tool puts our pack at 93 percent of its original 75.0-kWh capacity, a loss of about 22 miles of rated range from the original 310-mile EPA combined figure. 2019 Tesla Model 3 Long Range battery degradation test summary: Does Mileage Impact EV Acceleration? Now to the real meat and potatoes. To put things in perspective, according to theUS Department of Transportation Federal Highway Administration, Americans drive an average of13,476miles a year. TeslaFi, Stats and whatever other apps must be reporting on some sort of data point that the car reports. For example, our long-term Tesla Model 3 specifies that charging above 90 percent shouldn't be done for daily use, only for trips, although it doesn't explicitly say what the long-term ramifications might be for regularly going above that threshold. Charge the car to 100% and leave the car until it says it is not adding any more power to the battery. It is not a real gauge of your battery's physical condition and degradation. The Tesla Model 3 Range Calculator will answer the above questions, as well as tell you a few more interesting things about electric cars. 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. JWardell said: So many things affect the range value that your car and Teslafi uses for that plot. The Tesla Model Y is . A new Model 3 base trim has a range of about 272 miles. It can help mess up the calibration in the BMS. If you don't charge at a Supercharger daily, drive all over the country every week, slip and slide around various tracks, participate in your fair share of drag races, and hit the off-road trails from time to time, your EV may be less prone than Kyle's to issues and battery degradation. 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. The following is best done at the end of a drive when the battery is warm and factors such as vampire drain and cooling of the battery have not had chance to influence the results. If the car won't allow 100% to be set, this may be a calibration issue and address that aspect first. Very low or high ambient temperatures reduce the range by a factor of 1.5 to 3, which should be considered on long journeys. I think all that matters is that you can drive for two to three hours before your next Supercharger stop. When it comes to speed, 30-80 mph is the optimal range that guarantees efficient energy consumption. Research suggests that many EV battery packs, especially on longer-range models, are likely to continue providing sufficient range even after the vehicle itself is wearing out and even nearing the end of its life. If you suspect calibration rather than cell balancing to be the issue, e.g. Tesla battery degradation. Just how degraded is my battery? 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. I could knock up an equally subjective Excel spreadsheet with a line that goes upwards if it will help you feel better about it. Data collected by a Tesla owners' group show it's unlikely the Model S battery pack will degrade to less than 90 percent over 200,000 miles or even further, according to Electrek. When the temperature starts to fall below 10 deg c/50f there is increased demand to heat the cabin and battery, both through heaters and higher internal resistance of the battery, which consumes significantly more energy at the beginning of a journey. Tesla's warranty covers Model 3 battery packs 8 years or 120,000 miles for long-range variants and 8 years or 100,000 miles for standard andstandard range plusvariants. How many watts of power does the car use? This includes regularly using the Supercharger stations. Some posts may contain affiliate links. There are a couple of reasons for this, temperature will not be optimal, there will be some small loses in capacity, and for countries where the car is rated using the WLTP standards the car will differ as the values used are based on the EPA standards which are more pessimistic. 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. Choose the socket youre. All Tesla rights reserved. Owners often comment about the indicated battery range not being what it was, that charging stops short of 100% even when set to 100% or that they have heard about rebalancing the batteries. Tesla have applied a model 3 warranty limit of 70% retained/30% degradation after 8 years/120k miles/180km to be acceptable. 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%). If youve been staying at home, doing mostly short-range trips, and keeping SoC in the middle zone to preserve your battery, its a good idea to do a BMS (Battery Management System) reset once in a while to ensure its accurate when you are on a long trip. Cookie Notice Good thermal management means better protection against degradation. The battery degradation that Chris saw overtime was gradual with only 1 or 2 miles of range loss. In the case of an electric car, this degradation in its total energy capacity means that its maximum range shrinks over time. I am on 13,1k miles with 303 miles at 100% reported by teslafi this morning. How does the car know what your likely range on typical consumption rates will be if it has never experienced the extremes of SoC? . It's really simple, as you'll learn by reading this review. Please visit the Account Upgrades page for more details. Charge to somewhere between 90%-95%. Higher-performance Tesla batteries have been listed online at hefty prices. Even once a month, at a SoC below 50% can help. How does the weather affect the range of an electric car? For context, that's 12,500 miles a year, 240 miles a week, or 24 miles a day. 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. Okay, butwhat about battery degradation when you hit 100,000 miles, or say, 200,000 miles? In the end, the car proved capable of traveling 225 miles at a constant 70 mph, followed by about 20 additional urban miles until the battery's capacity and its buffer were essentially spent. Matthewshared his thoughts on how much battery degradation he's seen in his Model 3 after driving more than 50,000 miles. 2020 Tesla Model Y Review Pricing And Specs . Figure 2: Battery degradation comparison of the 2015 Tesla Model S (liquid cooling) vs. the 2015 Nissan Leaf (passive air cooling). For more information, please see our Tesla has bragged about the longevity of its cars and batteriesbut is there truth to the brag? If true, it would be a pretty good result. 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. This can take some time (an hour or so) after the car appears to have reached 100%. The 76 highest mileage Model 3 owners on hislist have accumulated2.9 million miles which translates to an average of39,372 miles driven for each car. One such issue happened with the Tesla Model 3 of YouTuber Its Kim Java back in 2018 when her car started showing 260 miles of range on a 100% state of charge (SoC) instead of 310 miles when it was new. To avoid the situation that Kim went through with her Model 3, the Battery Management System (BMS) of a Tesla needs to go through a reset. Plug the car in to charge, preferably on a AC charging point although you can also do this on a rapid chargerbut it may block it for others for some time. You are using an out of date browser. Conclusion There are many factors that go into how long a Tesla lithium-ion battery will last. Tesla EVs use lithium-ion batteries, like other EV batteries. This is based on the range data from the nearly 500 times we've charged our car to 90 percent of its capacity or above (see graph below). The car may have said it has finished charging before this, ignore the "finished charging" message and use the energy/voltage/miles readout to see if the car is charging. Its all extrapolation, I would ignore it. Do you value your experience at TMC? Tap/Click to open full-size chart (Source:FHWAviaX Auto). First and foremost be aware that battery degradation and the rated range shown for your car may be 2 totally different things. EVadept.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com and other sites. One of the options here to perform a battery health test. Does Tesla have a large amount of empirical data that it can base estimates on, or is there more theoretical science behind it? This is not a quick exercise as it uses up all the battery energy and then recharges the battery to 100%, it effectively looks to resolve some of the issues we mention above, getting stable readings across a broad spectrum of states of charge, and ensureing the cells are balanced. Tesla replaces forward radar with vision-based Autopilot/FSD on its website, Tesla invites artists to help cover Giga Berlin in graffiti art, battery degraded only 2% after 50,000 miles, Tesla Model 3 cost of ownership after 2 years and 50,000+ miles, Tesla Model Y Quicksilver color is a hit in Europe, looks fantastic in person (pics, videos), Tesla drops prices of its Model S, 3, X, and Y vehicles (complete list of new prices), Tesla (TSLA) sales crossed a total of 100K in Norway in 2022, the electric automaker saw a 32% growth YoY in the country, Traction of a Tesla Model Y AWD tested in the snow using Off-Road Assist mode with all-season tires, SpaceX stacks Starship 24 on Booster 7 for prelaunch tests before the first orbital flight in Feb or March (videos). The BMS will try and keep all cell modules at the same terminal voltage when the car is in the final stages of a full AC charge (it doesn't do this when DC charging), and in terms of diagnostics, looking at the cell module voltages at around 50% SoC will give a pretty good indication as to whether there is any problem with the pack. Above:Model 3 battery degradation at 50,000 miles (YouTube:Tech Forum). Model X and . 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). All data is provided on a reasonable endeavours basis but errors and omissions may exist. Your use of the tesla-info website is subject to these policies and terms. They have not stated a figure for the MS or MX. Multiplying these 2 together gives a figure, which when divided by 1000, equates to the number of driver available kwh in the battery at the current state of charge. Parts Theft - No expensive catalytic converter to be stolen while the vehicle is parked. . It has always shown that I get around 210-220 miles at 70%, which is about right because 70% of 310 is 217. The car is 3 years old and covered 164,541 km (102,263 miles), which is quite a substantial distance. Conner has certainly taken care of the electric sedan, but he isn't one to baby it or take it easy, to say the least. It offers loads of insight, and he promises another video going into TeslaFi in much greater detail. What we really appreciate about Kyle's new series is that many EV owners may be able to look at his ownership experience as a sort of "worst-case scenario." Tesla have applied a model 3 warranty limit of 70% retained/30% degradation after 8 years/120k miles/180km to be acceptable. We recently did this same test with a 2019 Tesla Model 3 dual-motor long-range. Take it on a long drive until the battery drops below 50%. The example is from a Model 3 Long Range with a BT37 battery and shows negligible degradation. Did you expect more or less degradation? Discuss Tesla's Model S, Model 3, Model X, Model Y, Cybertruck, Roadster and More. 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. Image courtesy of: Ian Pavelko. We may earn a commission for purchases made through our links. This is one of the most comming queries from new orders where their factory fresh car does not show the range the spec sheet showed and is entirely normal and correct. That said, in a perfect world, if you buy an EV and its battery either stops functioning or degrades too quickly, it should be covered and replaced. He says he would have liked to drive. Copyright Digital and Analytical 2023. Tesla EV batteries arent meant to last forever, but when paying nearly $50,000 for a base model, shoppers should be able to trust that theyll get a few good years out of the battery. Do you run centry mode often? Consequently the car will have few, if any, readings at lower states of charge. Clearly, battery health/life is a major part of the car's long term value. Copyright 2023 Endgame360 Inc. All Rights Reserved. We have created a Battery capacity calculator tool that can get information via the API that will calculate the battery capacity for you. 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. Battery range degradation graph - 22 MYLR. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Tesla Model 3 Battery Capacity After 8,610 Miles : r/teslamotors. To get a stable reading, the car needs to be left in it's sleep state for several hours. Reports suggest there is an initial drop within the first few months and then the rate of degeneration tails off. Model 3 Standard Range Model 3 Rear-Wheel Drive 8 years or 160,000 km, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period. Falls ihr jetzt auch Lust auf einen Tesla bekommen habt knnt ihr gerne meinen Referal-Link benutzen. (Seriously, if you have a Tesla, sign up for TeslaFi.). The above calculates the available battery capacity. Early Tesla Model 3 owner Ian Pavelko has compiled the following steps for a BMS reset. This is the type of battery youll find in most Tesla EVs, though the expected range varies based on the model. LFP's does suffer from calendar aging, as all lithium batteries. Tesla CEO, Elon Musk, has stated that the Model 3's battery was designed to last 300,000 to 500,000 miles, or 1,500 charging cycles. If you are still worried after doing both these things, then contact Tesla. Tesla model 3 reichweite erfahrung. Often modern electric cars, such as the Tesla Model 3 are equipped with batteries that give about 250 miles of mileage. Set the charge limit to 100% and leave the car to charge. First is a long description in a long thread. Tesla batteries are lasting much longer than 200k miles / 320k km pic.twitter.com/z882nf6yv9. 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. Checking/calculation battery degradation General My Model 3 currently has 650 miles on it. Calculator that estimates Tesla Model Y Long Range AWD charging time and cost. Leave the car overnight and/or in the day occassionally without sentry mode enabled allowing the car to deep sleep for several hours. Newer Tesla Model 3 Long Range electric vehicles equip an 82 kWh 350V lithium-ion battery pack. Repeat the process a few times if necessary. Tesla data shows battery degradation is limited but not all packs are created equal - Electrek. Please email us if you find figures that are significantly different using the approach as this guide is provided based on community sourced information. 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+. Kyle notes that he uses TeslaFi to keep track of all his Model 3's data. 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. When the car reaches what appears to be 100% it may well say it has finished charging but it is drawing current. Excluding the Sentry Mode usage, the estimated loss of range is only 5% according to the owner's estimate. So, the total loss at over 100,000 miles is around 10 to 11 percent.
