An exact Wh is not going to be possible. They are all estimates. A battery is not like a gas tank.calverajarda wrote:Hi,
i have problem about consumption. I dont know what is right.
Yesterday driven 26km - car shows 12,4kwh/100km its 3224Wh
With leaf spy at start capacity 16,1kwh, at end 12,2kwh its 3900Wh
Consumption wit Leaf Spy135,1Wh/km - its 3512Wh
I searching true conusmtipon kwh/100km with clima, heating etc.
LeafSpy uses two different ways to calculate Wh used. One is based on a change in Gids and the other is based on battery energy level changes.
Wh per Gid is not a precise number. The default is 77.5 Wh per Gid but you can change that in Settings/Battery. Also Gids when SOC is high seem to have less energy than Gids when SOC is low. After a full change the first bar goes away pretty quickly compared to later in the drive.
The Battery energy level has <1Wh resolution which looks great but a battery can change its available energy just by having the battery temperature increase or decrease. Battery energy level changes also includes all accessory energy use.
LeafSpy's efficiency number (energy/distance) has the problem of energy listed above plus the fact that the odometer only changes in 1 km steps. It is not something I would have put in but was requested even with the short comings.
