Is it Normal for LFP Tesla 3 SR to Lose Range Over Time? Understanding Battery Degradation in EVs.
LFP batteries are a relatively new technology in the electric vehicle industry, and as such there is not much real-world data available on how they degrade over time. A Tesla 3 SR owner recently asked if it was normal for their range to drop from 273 miles to 267 miles at 100% charge after only 4 months of use and 4000 miles.
The primary factor that affects range in an EV is temperature - when it's colder outside, range will be lower than when it's warmer. It's likely that this change in range was due to the weather changing from the time the car was first purchased.
It's normal for NCM Teslas to lose roughly 5% of their range in the first year, then 1% per year after that until a maximum of about 10%. This means that even with degradation taken into account, the Tesla 3 SR should still have a range of around 270 miles at full charge.
When looking at estimated miles left as opposed to battery percentage, EVs usually show an estimate based on recent driving habits. However, Tesla cars appear to reset to EPA estimates at 100%, making them more useful for determining battery degradation. If you want a range estimate that takes driving style, weather, temperature, etc. into account, use the Energy screen in the car instead.
Overall, it appears that the decrease in range experienced by the Tesla 3 SR owner is most likely just a temporal anomaly caused by changes in temperature rather than actual battery degradation. As long as they continue to get around 270 miles of range at full charge, their battery should still be performing optimally.However, if the range continues to decrease over time and they don't get around 270 miles of range at full charge anymore, then it's likely that their battery is starting to degrade. In this case, they should contact Tesla for further assistance.
It's important to remember that LFP batteries are still relatively new technology and there isn't a lot of real-world data available on how quickly or slowly they degrade over time. As such, it can be difficult to determine whether a decrease in range is due to actual degradation or just an anomaly caused by external factors like temperature changes.
In conclusion, while it appears that the Tesla 3 SR owner experienced a temporal anomaly rather than actual battery degradation after 4 months and 4000 miles of use with their car - as long as they continue getting around 270 miles at full charge - monitoring future performance will help them determine if any issues arise in the future which may require further investigation from Tesla themselves.
Is it normal for my Tesla 3 SR range to drop from 273 miles to 267 miles at 100% charge in 4 months time?
It is normal for NCM Teslas to lose roughly 5% in the first year, then 1% per year after that until a maximum of about 10% loss. A BMS reset could be in order if the car only shows 97% at what it thinks is full charge.
How can I view battery degradation?
The estimated range at 100% charge will always show the EPA estimated range and can be used to see the degradation. The Energy screen in the car takes driving style, weather, temperature, etc. into account.
What explains the discrepancy between SOC on top when shown in miles and the number shown in the Energy screen?
The one on the top always shows the EPA estimated range which takes any degradation into account. The Energy screen takes into account driving style, weather, temperature, etc. and can be used to get a more accurate estimate of the range.
What is the best way to monitor battery degradation?
The best way to monitor battery degradation is to keep track of the estimated range at 100% charge over time. This will give you an indication of how much degradation has occurred. Additionally, keeping track of the energy used per mile can also help in monitoring battery degradation.
How can I reduce battery degradation?
Battery degradation can be reduced by avoiding extreme temperatures, charging only when necessary, and using regenerative braking whenever possible. Additionally, it is important to ensure that the car is always kept at a full charge and not left in a partially charged state for long periods of time.
Is there any way to reverse battery degradation?
Unfortunately, once battery degradation has occurred it cannot be reversed. However, there are some steps that can be taken to slow down the rate of degradation such as avoiding extreme temperatures, charging only when necessary, and using regenerative braking whenever possible.
