Do EV manufacturers give any info on battery charge loss whilst the vehicle is idle? We used to call this quiescent current when I was employed in electronics? The reason I ask is that a neighbour recently returned from a 3 week long haul holiday and found that their parked up EV battery had drained. They had initially travelled the 200 miles or so to the airport and rapid charged the battery before their flight departed planning a swift journey home on returning, the charge costing about £50 (airport prices I guess?). They then had to spend a similar amount on their return which was somewhat annoying after the 15 hr flight. There do seem to be anecdotes on some EV forums regarding idle battery drain. Any EV owners out there know if this is a common issue? Are some manufacturers better than others in this regard?
