Update again on the 260Ah Winston LYP pack.
We are now 8 years past, since fitting this pack.
I drove the normal drive, but there is quite a lot of roadworks so a mix of driving speeds. Drove 106km using 20.1kW. I didn't zero the kW reading before driving and don't remember what it was before I started to drive.
Charge by solar. Charged 156Ah.
Some may be wondering how I charge 168v from 48v (56v full) solar system. I use 3 x 48v solar systems, each to a separate section of the pack.
And after charge the EV Hilux monitor screen reads 1.5kw past the zero point so could be said 20.1 + 1.5 = 21.6kW, but the monitor tends to go past zero anyway, so it is not definitive.
The standard speedo was disconnected some time earlier this year. It sounded like a bunch of canaries in a feeding frenzie. It was still ticking over the numbers but disconnected at 601745km.
The VDO speedo now has 120248.9km on it. Last years reading was 106811km. That makes 13437km for the year. (we have T-Rev registered so it does some of the driving)
13437km plus total from last year 155443km = 168880km driven on this 260Ah pack over 8 years
Cost
Found a mistake in last years numbers.
Cost of this pack was $1.40/ah x 260ah x 52 cells = $18928
155443km / $18928 = $0.082 per km. (8.2 cents per km) This is wrong.
It should be calculated $18928 /155443km = $0.12 per km.
So this year, the cost is now calculated at
$18928 / 168880km = $0.11 per km
