Hi Xan
Don’t worry about anything like that you run the car however you like and suits you best, no one is going to even look at how it’s been charged. Motability will let you extend the lease but only whilst you’re waiting on you next car to be delivered. The days of extending leases for up to 5 years for “normal” cars is gone now sadly, you’re right things may change again but I highly doubt it. I don’t think the depreciation issue will go away until the media stop fearmongering all the time but expecting them to do that is like asking them to stop blaming immigrants for all the country’s problems it’s not going to happen. Your logic is sound in theory but Motability seem to have their own ideas on these things.
Maybe once the new sodium batteries become more mainstream in cars that’ll stop the EVs all catch fire bridge from their endless BS.
I charge mine to 100% almost all the time, I don’t always rush to immediately charge every night so there’s that. I often hold off in order to make use of Octopus when they have free power etc especially when I know there’s a storm incoming as there’s usually excess wind power on the grid then like this weekend with 3 hours of free power.
Good luck with the apps, don’t worry too much about Motability and just use the car to suit you
