You can reach him on Twitter @IqtidarAlii. Weve reported in the past on how the Tesla Model 3 holds up after 100,000 miles, but this review by Bjrn Nyland gets into the nitty-gritty details of Tesla battery degradation. Copyright 2023 Endgame360 Inc. All Rights Reserved. Check out our Guide to Tesla BMS calibration to the nature of the issue and how it can be resolved if you suspect it is needed. Compared to 158 other Model 3s at similar mileage that are also connected to TeslaFi, our car is faring worse than 123 of them and better than 35. Tesla Model 3 Maintenance Costs My full warranty ran out at 50,000 miles. Can a Tesla Model 3 battery last as long as owners would like? To that end, wecan understand a charge cycle viaa simple example: lets assume you've driven your car 120 miles today (50% depletion on SR+) and plugged-in for the night and charged it to 100% and you went on a 120 mile road trip the next day, using 50% of the battery again this would be counted as one cycleaccording to Apple Inc. It's the same as with a smartphone - use it sparingly or watch videos until it runs out. So, the total loss at over 100,000 miles is around 10 to 11 percent. It offers loads of insight, and he promises another video going into TeslaFi in much greater detail. 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. the car has not been left below 50% for some time, then you can focus on BMS calibration going forward. Some owners have experienced a sudden range degradation only after driving the car for a few thousand miles. 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. This drift is fairly negligible on a Model s and Model X but can be more significant on a Model 3 and Model Y. 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%. 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. Read on to learn about it. Kyle notes that he uses TeslaFi to keep track of all his Model 3's data. 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. Let the car run down to a low state of charge, below 20% is good. Range however will vary quite considerably over the course of the year due to a number of factors, most noticeably from a seasonable perspective, due to weather. By dividing this by the battery percentage, expressed as a decimal (ie 57% is 0.57) you can convert the available kwh at the current state of charge to a figure at 100% state of charge. 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.

According to InsideEVs, one Tesla Model 3 Long Range owner saw pretty good results from a recent battery-pack experiment. All data is provided on a reasonable endeavours basis but errors and omissions may exist. Ways you can support tesla-info, 95 (although some report as high as 98 usable), Things to do when you first collect your Tesla, Sentry mode amd boombox storage configuration, Calculate and Bench Mark Battery Capacity via the API, Tesla model history and changes over time, Tesla window is open and will not close properly, Tesla Supercharging Expired payment card issue, Tesla safety report and the need for caution, Headlight alignment and stop dazzling other drivers. 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. Tesla model y long range battery replacement cost. Higher-performance Tesla batteries have been listed online at hefty prices. 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. View results; Share online (tag @teslanomicsco) Tell others! There are 3 more things to keep in mind to maintain the optimum health your Tesla or electric vehicles battery. The use of cookies is a standard industry-wide practice. The following steps are fairly simple and are not required to be done that often to help the BMS achieve a good level of calibration. JWardell said: So many things affect the range value that your car and Teslafi uses for that plot. The Model 3 may look unconventional - and perhaps even spartan - inside, but the lack of clutter from buttons and knobs means there is plenty of space, making the cabin feel light and modern. To get a stable reading, the car needs to be left in it's sleep state for several hours. The Tesla Battery Management System (BMS) is responsible for looking after the battery. Newer Tesla Model 3 Long Range electric vehicles equip an 82 kWh 350V lithium-ion battery pack. Our battery's degradation thus far equates to a drop of roughly 2.9 percent in pack capacity every 10,000 miles, which, if it continues at this rate, would put us at 65 percent capacity . The table below gives a range of batteries and there capacities. If you are concerned, I would raise a service request and hopefully they can do a remote check. By his reckoning, we are both still in the early phase. But not everybody drives like the average Joe. Tesla Model 3 loses only 2.2% of battery range after four years and 100k miles. 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. The AVG consumption, the Projected range and the Percent. We're not too surprised that we're doing worse than average, as fast charging at Tesla's Superchargers is not great for maximizing the battery's life, and we've gotten fully a third of the energy our car has used that way. 360 Rear, side and forward-facing cameras provide maximum visibility 250 m Powerful visual processing at up to 250 meters of range Tesla Vision detects nearby cars, helps prevent potential collisions and assists with parking Autopilot's advanced safety and convenience features are designed to assist you with the most burdensome parts of driving. . 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. I've watched a few videos by Bjrn Nyland on long-term degradation. Every time I see people talk about battery degradation, they use a method that I believe is incorrect for measuring it. 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. Out Of Spec Tests Two Teslas. One of the options here to perform a battery health test. Are you unable to get to the destinations you need to get to? More specifically, it's a 2019 Model 3 Performance that's been put through the paces from day one. Now to the real meat and potatoes. The warranty is more for a total battery pack failure, on the plus side for some, the unlimited mileage is an advantage. 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. The battery degradation that Chris saw overtime was gradual with only 1 or 2 miles of range loss. My Wh/mile hasn't really changed (~265 Wh/mile). . Figure 2: Battery degradation comparison of the 2015 Tesla Model S (liquid cooling) vs. the 2015 Nissan Leaf (passive air cooling). I dont think so. 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). InsideEVs suggests that battery use, that is, the number of charging cycles, may play a bigger part than the actual age of the battery. All Tesla rights reserved. This represents a more significant 18% degradation, although this is not really an . Excluding the Sentry Mode usage, the estimated loss of range is only 5% according to the owner's estimate. That's a very good result of just 10% battery capacity (and range) degradation: 1% per 20,000 miles (32,200 km). My battery and drive system warranty will run out in another 40,000 miles at 120,000 miles. Do you value your experience at TMC? This includes regularly using the Supercharger stations. Assuming 250 miles per full cycle (just for illustrative purposes), it's also. Do you run centry mode often? If the figure is above that, for instance the car is an 85 and have been hit by #batterygate, then react accordingly if buying or if you are an owner then consider challenging Tesla and get the issue logged if in warranty. Please email us if you find figures that are significantly different using the approach as this guide is provided based on community sourced information. Turning off 3rd party apps that keep the car awake, and don't query the car with the Tesla app unless necessary while doing either of the above. 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. If you suspect calibration rather than cell balancing to be the issue, e.g. After the launch of the production version of the Model 3, Tesla announced . Don't forget, the battery stores energy, not miles, and the mileage figure is based on a conversion factor applied by the car i.e. To address this, the battery benefits from a 100% charge. 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. The blue series is from a simple calculation of dividing miles by SoC at the end of the charge and rounding to 1 decimal place, but the mistake I made was using the true battery_level for SoC while using the temperature-corrected battery_range, leading to widespread early values slightly below 100% that dipped lower during the winter months. I've been charging it to 70% since I got it.
