Maybe Nissan should study one of the older Ranger EVs as Ford had this figured out 10+ years ago...

When I was at the front of the room w/several others (pretty sure w/Mark Perry) after the meeting was over, my recollection was that he said the GOM used to jump around all over the place and that the TSB referenced smoothed it out. Hopefully someone else can either correct or confirm the conversation and elaborate more...Herm wrote:Poppycock!
they need to smooth it out, people drive the same way every day, it averages out.. just use an average number for miles/kwh and keep track of the remaining capacity.. easily done to +/- 5%.
You recognize that Gary's SOC meter does not do anything more fancy than display Nissan's data? They already have that info.TurboFroggy wrote: I think how Ford does it is measue the KWH in/out from the pack then make a judgement based on the power draw with lots of averaging/samples. This smooths out the DTE meter reading and makes a much more sane and accuate reading.

Sure you can, most people drive to work everyday using the same route, at the same time, in the same traffic jam, and at the same speed, and usually the same person is driving that car.. obviously for a small minority this wont work.cwerdna wrote: As for "people drive the same way every day", you can't make the assumption. Cars can be switched between different drivers and cars don't always follow the same routes.
Have an "expert" page on the nav that you can select data for you future trip.Herm wrote: How would a GOM that uses a 2 week average impact you?.. is there another way to satisfy your special needs for those special days?
My 2000 Ford Ranger DTE isn't 100% linear. Sometimes it will drop quicker than usual in the bottom half of the range and cause a bit of range anxiety. At least in part, I concluded the following:TurboFroggy wrote:On the DTE meter topic: my 2000 Ford Ranger EV has a pretty darn accurate DTE guage. It doesn't jump around like our Leaf's does, it is rock solid and very accuate.

Yes, I was there. Heard the same. I mentioned "maybe a longer history of data, and more smoothing would help some."cwerdna wrote: When I was at the front of the room w/several others (pretty sure w/Mark Perry) after the meeting was over, my recollection was that he said the GOM used to jump around all over the place and that the TSB referenced smoothed it out.

How about a modification of that thought... When the car starts up it uses a long-term average (2 weeks?). It then uses the same algorithm that it uses now for the rest of the driving cycle.Herm wrote:cwerdna wrote: How would a GOM that uses a 2 week average impact you?.. is there another way to satisfy your special needs for those special days?
