Leaf battery get status

[mbu10]

Good morning
Have got a leaf battery
Can I Without turning on the battery out put
To switch on it on so I can read the status of the cells and voltage?
Thanks
Martin

Yes, see this page for more info on how to check the health of a pack before purchasing it: https://github.com/dalathegreat/Nissan-Leaf-Battery-to-OBD2

Yeah thanks so much for that.
Could but do in this case but will keep in mind in case I decide to at another battery,
This one was 700 UK pounds
So if that calculated 21 KW , I think that's a ok price

@Dala
morning
Just been thinking about the calculations on max and min soc within the inverter and battery
So if you set the inverter to 80% and 20% and you have the same figures in the emulator
Would you not have
Emulator 40% that you do not use
And inverter 40% you do not use...

But if you then take that 24kw and remove 40 %(emulator restrictions)is 14kw usable of 24kw battery from the emulator side

But then if your inverter is following the same rules cause of scaling(so it sees 100% (at 80% ) and empty at 20%)

Does that then mean that 14kw has a 80/20 (inverter side limits)with 40% is 5.6 which means 8.4 usable

I am sure this is not the case
But thought would ask

Yes, only set limits in one system, otherwise you are doubling up the restricted capacity!

Thanks so much , could not find that any where , maybe add to the wiki so that others know, it your loosing so much , thanks so much for the reply

Just tried to on the inverter fox h1 would only let me drop to 20 lowest

@Dala have posted my build the other question cause I have double lilly does the first one need to be 80/20, then the inverter side need to be 100/0 ?

 

[mbu10]

So here is the inverter and battery side
Screen shot
The battery side says the scale should be 74 and real 64
The inverter side is reporting only the real one ?
Or an I making a mistake here

I have swopped this around now, say the battery side showing full no scaled battery to in self and the lilly connected to the inverter, the inverter one now shows the what I would think the correct soc is
