If that's true, what's the point? Why do we need another unit that means the same thing?
AFAIK, it was found to be ~281 on a brand new battery at full charge. It went down as the battery discharged and went up as the battery charged. See http://www.mynissanleaf.com/viewtopic.php?t=5582.GRA said:The term "Gids" has nothing to do with Nissan, that's the name they were given here on this forum in honor of Gary Giddings, who developed the first aftermarket CANbus battery monitor for the LEAF, the gidmeter. I have no idea why Gary choose to use that value, but I'm sure you could ask him.
Yep on all of this. I don't know there's an agreed upon value of that's 100% correct all the time as to how many Wh it corresponds to or what the range can be. So, to answer the OP, sure, you could use kWh, but you could have GIGO (Garbage In Garbage Out). All you have are gid values and to apply * 75 or * 80, well, it might actually be wrong.91040 said:As stated by Nubo, the value was created by Nissan. GaryGid and Turbo found a data stream on the EV Can that corresponded to the available energy in the battery. Not knowing what Nissan called it, this forum coined the name. It seems to be about 80Wh into the battery and about 75Wh out.
Which is exactly why I'd say it's not a great idea to multiply 75, 80 or whatever by gid # and conclude the battery really has the result as the # of available kWh.91040 said:Gids are defintely not linear. They don't seem to hold as much energy per unit at the very top of the range than the rest.
