What would you record during your first month with an EV?
Keep a simple record of distance, purchased charging energy, session cost and the source of each consumption figure. Note conditions that make journeys unusually different, such as a new route or cold weather.
Separate observations from impressions. A receipt, a trip display and a personal judgement about convenience each answer a different question.
Check that accounting periods match and keep private documents off the public site. After a month, the record can help improve a budget and identify useful questions; it is not automatically a battery-health test.
