The temperature gauge was at six bars, in all the vehicles I have looked at, of course...tbleakne said:While the Gid meter is not official, its readings were acknowledged by the Leaf Chief Engineer at the Dec 1011 Google meeting of BayLeafs, where he confirmed that one Gid is calculated to be 80 Wh. If the car that went 11 miles over its predicted range is one of the ones with the most capacity loss, this would suggest that we (or Nissan, if we can trust them) can develop some kind of modest correction to the Gid count, but it is NOT going to explain ALL the capacity loss at high temperatures. The Chief Engineer alluded to the difficulty of computing an accurate Gid count, and that was without considering battery capacity loss.
Wouldn't it be likely you would get more consistent results in comparative capacity tests by normalizing the battery pack temperatures while charging?
Was that done?
