Tesla's recent report on battery life is a game changer for EV owners: 'We have a reliable data set' (msn.com) "Tesla detailed the average battery-capacity retention per distance traveled of the Model 3 and Model Y cars with Long Range battery packs. For both models, the average battery capacity loss after 200,000 miles is 15%. In other words, the average capacity retention after that distance is 85%." That is an amazing statistic, Tesla is to be complemented on their battery life for their vehicles
Personal observation in Dixie, the SuperCharger network grew faster, nearly 2x, in 5 years than my battery degradation. Adding the CCS-1 charging option, again nearly doubled the number of fast DC charging options. A CCS-1 charge can bridge a gap to follow a direct route, saving miles. CCS-1 has gotten 'less bad' at established public stations. Bob Wilson
It's as if not cooling the battery properly is having a negative effect on its longevity. Who could have predicted that
Toyota with the Gen 1 pack. I had 2003 Prius and optimized the car by an early battery pack upgrade. Further testing revealed a weak, terminal seal and operating at speeds over 70 mph led to battery heating. Add to that, going up and down hills, the battery pack would get hot enough to melt the "O" rings leading to water loss from the electrolyte. I prefer the NiMH battery chemistry because there are no losses in active chemistry. There is some electrolysis to hydrogen and oxygen but given a rest period, the NiMH would catalytically recombine them. Is was loss through melted "O" rings that heralded the eventual cell dehydration and death from separator melting. Bob Wilson
One of the big differences between Honda and Toyota NiMh is that Honda stopped using NiMh completely around 2016. It's sure not the only big difference, but there is that too.
