X – Some really good answers have been provided to your questions from those who know far more about EV’s than me, but in reference to DumfriesDik’s very good point about quoted range versus real world range, there was an interesting thread on this recently. Even with 100% charge, EV drivers were reporting that actual range can be quite a bit less than quoted range especially in the winter months, so you will need to allow for that, on top of any shortfall that only charging to 80% will result in.
