Over 4 years or so, batteries that have never been supercharged are at about 90% capacity rather than 80% for frequently fast charged vehicles. Given the rapid decline of batteries in their final months, that could be equaling an extra couple years of usable life. That's an issue in a car, but a massive deal in a semi where they need much, much larger batteries with much, much larger replacement costs. The real solution here should have been battery exchange contracts. They make facilities to slow-charge batteries and semi's pay per mile or kw he put on the battery. The would be much better for the environment. It would also enable Tesla decreasing the up front cost by moving some of that cost into charging fees to encourage adoption. https://www.geotab.com/blog/ev-battery-health/ https://www.geotab.com/blog/ev-battery-health/
