Re: What is a "Gid"?

Today was the first time since I build my meter that I charged to 100 percent since I have a long ways to go today... I got exactly 280.

No, I just said I had done it on my car, it is not the same exact mod and it is difficult to do and performs differently on different VINs. My car does not have the firmware for tilting lights like later models.

Sorry if I'm a little hair-trigger, I've been dealing with the constant inundation of idiots emailing and calling me after the yahoo article surfaced. There are people really pissed about this, and I'm getting all kinds of haters and crackpots coming at me. It's truly a shame there is that much anti-EV sentiment!

Wow, I just linked to the Yahoo article and read some of the over 2,000 comments. What a cross section of know-it-all, closed minded haters and perpetual motion believers! Sorry you're being plagued by these people, Phil.



I posted about these comments in the ev haters thread but there was not much attention. These are the worst comments I have ever seen related to EVs and in such a high number. Few people defended the dumb comments.

I was not aware that there had been any running changes in the tilting light software... Mine is pretty early and has the tilting light feature...

The Battery ECU computes SOC and Watt-hours remaining by 2 methods; One is by coulomb counting with a hall-effect ammeter, and the other is by watching open-circuit voltage of the pack and performing a complex calculation based on multiple inputs. Because the coulomb counting method has some drift due to the hall-effect system, Periodically the battery ECU will dynamically adjust these figures to keep them accurate. This is why the apparent charge drops a little faster initially sometimes.

I do not believe the combination meter is using this figure to calculate bars, this calculation appears to happen in the EV ECU. I will check to be sure at some point.

Another interesting question would be the SOC value when car runs out of juice. Does it go to zero or not?

Obviously, the true battery SOC does not go to zero, as that would damage it. The Gid count goes to a very low single digit value (like 1 or 2).
