Hi Guys,
I am trying to figure out what the usual battery degradation is for Tesla batteries in Hong Kong. There was a study done in the US which concluded that the AVERAGE Tesla Roadster's battery retained 80-85% of its original capacity after 100,000 miles (or 160,000 kms).
Other studies have suggested that a typical Lithium Iron battery degrades to 80% of its original capacity after around 6,000 full charge cycles. So for instance, if you own an 85kWh Model S, with mileage of 220Wh/km, it would imply that you would hit that in over 140,000 miles or over 230,000km. This is based on charge cycles alone (which would be overstating its life) as there are other factors influencing longevity.
For instance, I discovered that mean temperature actually has a bigger impact on long term battery life than the number of cycles. i.e the lower the temperature, the longer the battery life. (Ironically, the lower the temperature, the worse it is for mileage). Given that HK has a warm climate compared to the USA as a whole, one would expect that the longevity of the battery in HK would be worse.
Does anyone here own say, a roadster that has done anything close to say, 100k kms to give an indication on how their battery has lasted compared to when it was new? Or anyone who lives in a warm climate?
Cheers
