No, what he is saying us if you charge to 100% don’t leave it there, try and keep it below that figure and don’t run your battery down under 20% as tgat can effect the longevity of the battery.
same as ICe cars, don’t run them down to zero either.
The point is you don’t run an EV the same way you do an ICE car, I.e. run the tank low then fill up. Majority of people don’t go hundreds of miles a day, the average is around 25-30 miles a day, with one or two trips of 100-200 in a year.
