After years of over obsessing about 20-80 charging, I'm officially done. The data is in, for normal users, there is no significant benefit of charging to 80. Obsessively plugging in each night isn't great either as it will keep the vehicle in an extremely charged state, but the most normal type of charging behaviour is just fine. And by normal, I mean treating it like an ICE vehicle: charge it full, use the car, charge it full again when it gets low-ish, rinse, repeat, have a nice life. The other big takeaway is to limit high speed charging if possible. Overall, it reaffirms that these vehicles have buffers and do not need to babied unless we are obsessed with eeking out every last morsel of battery life ten years from now. For the two EVs I own, and use mostly for local commuting, I just no longer care about optimizing to the point of obsession. If my 320 range drops to 250 in ten years, my life will still be just fine vs. the 270-280 I might have retained through more obsessive charging practices.i have officially turned off the 80 percent limit. Filler up baby!
