Typically you charge to 80% to ensure battery life and recharge before 20%.
I've seen this loads of times, and it has made me wonder. I've only ever owned one EV, our Mini has a 34kWh battery that is limited to 28kWh of available capacity. BMW advice is that you can safely charge it to 100% as the unavailable capacity acts as a buffer to prevent any issues. It seems such an obvious strategy I wonder why it's not more widely implemented.
On the range issue, I would think for a local run-around the R5 would be fine. The Mini has a theoretical range of 140 miles (realistically 120 miles in the summer, 95 in the winter) and we've never come anywhere near running out of range for the use we put it to.
