Suddenly losing range

[snowgoose]

I would say that it's worse than a guess; it's a WAG. It's complete fiction. May The Force Be With Them Who Believes It.

When there is no excess friction from the brakes, I find the gom is pretty accurate. As I have said in this post, most of my driving is on country roads and I consistently drive at around 40mph and rarely more than 50mph. I have eco turned on all the time and I don't thrash the car. Yesterday I did 4 trips totalling 55 miles and the gom dropped 54 miles. This is what I experienced ever since having the car (apart from when I had the problem with something binding). Where I guess it wouldn't be accurate is if you did a 50 mile journey one day at around 40mph and then expected the gom to be accurate the next day when you drove to 80mph with eco off.

I have had my LEAF for over 13 years. I religiously keep record of every bit of info every I charge: date & time, temperature, indicated energy economy, tripmeter and odometer, average speed, miles and bars remaining. I used to keep track of the GOM number as well but I gave up after a couple of years because I found it as useless as tits on a boar hog, as they say here in Tay-siz . I have never seen the GOM number read anywhere near what I actually get. The vast majority of my driving is the same: commute and errands, all around town.

So, my position is still that the GOM number is useless. But, nobody should take anybody else's word on anything, so I encourage everybody to keep careful record for about a hundred charge events and see what they get.

I should add that the GOM number is not always useless. In my experience, in my 2011 SV, it's useless at 80%-100% SOC. The nearer the battery gets to empty the more accurate the GOM number becomes. At two SOC bars or fewer the GOM number is very reliable.

I find on my 22 I that it's quite acceptable but conservative which to me isn't a big problem.
