A lengthy discussion took place when Carol on the Tesla Cybertruck Facebook group asked a question about Tesla Superchargers and that if using them too much would damage battery life. Carol asked if this was true or a myth, creating quite a discussion. Carl Pitt said: You should be fine. If you were an Uber driver using it 2-3 times a day it might shorten the life of your battery. Charging at home with 240v is best and I wouldn’t recommend buying an EV unless you could charge at home. Mike Brooke said: I charge 4-5x a week with superchargers. Also charge at home to 100% another 4-5x a week. I've lost about 20% battery capacity in 195,000 miles. Charge at home if you can. Superchargers cost as much as gas. (in CA anyway). Gregory Smith said: My car is a 2017 X. I have free supercharging for life. I have been using superchargers this whole time. Minimal range loss. Way less than they projected. I have a home charger now as well and always charge to 100%. David Stutz said: Myth. Letting the charge continuously go to 100% or below 15% reduces the life of the battery. Steven Day said: Charged to 90% daily, supercharged for 100K miles worth of road trips. 2018 Model 3, 256 miles of range left when I traded it in last month. Probably going to keep my truck at 60-80% daily. Try to maintain a little better range over the years. Raleigh Burns said: With a Tesla it's a myth. As many posters have indicated, Tesla's battery management is stellar, but so is the thermal monitoring and management. It's quite worth the bit of research investigating the differences between AC and DC charging. When you're 'supercharging,' you are charging DC. Understanding that facilitates a better understanding of what the chargers actually do. Your Tesla battery is a DC battery and your pack is high voltage. 400-800 volts, depending on the model. To get that charged using 220v requires higher amperage and can cause heat build-up. Tesla's data indicates that long term, DC "supercharging" has no noticeable impact on battery life, but keep in mind they make a hell of a home charger and continuously manage the thermals and charge capacities of that charger. Daniel Duthie said: Supercharging does not damage the battery, many studies have been done to disprove that. What is bad is letting the cars (non LFP) sit at a 100% or 0% for long periods. Charles Jones: Charging at home is most convenient. Supercharging is a bit more "stressful" on the battery than AC charging, but 80% should be fine. Most people don't charge to 100% because not only is it "bad" for the battery (unless you are road tripping), but it takes a long time to charge from 90 to 100 percent because the charge curve ramps down. Some Teslas (newer Model Y) have LFP batteries that can be charged to 100% with very little degrading effects. You also have an 8 year battery warranty, so in worst case and your battery degrades massively, Tesla will replace it for free if degradation reaches 30%. These comments collectively suggest that while regular Supercharging doesn't significantly impact battery life, charging habits like maintaining charge levels between 20-80% and avoiding frequent full charge cycles (except for LFP batteries in newer models) can help preserve battery health. However, the overall consensus leans towards Supercharging being safe due to Tesla's robust battery management system. Do you have a Tesla or another type of EV? Have you charged at Supercharging mostly, or home charging? Does your experience fit with the comments here? Share this article with friends and family and on social media - or leave a comment below.
