(The battery and monitor thread )Car dead in the middle of the woods

[das mo]

Hi all.

Car is dead.

Battery was at 50% 2 hours back.
We now packed all together and car does not start.

Is there an Ineos support hotline I can call on a Sunday?

Thanks

How does this make any sense?

That you know, how the battery charging procedure work or not, and that we can tell Ineos that something have to be changed or change by ourselves, and important that noone else will have the experience of @das mo . I want to know before, that battery is down.

Sorry @Lollo050968 you misunderstood me or I wasn't clear. I was commenting on the actual numbers not why you have the monitors. I have one on my second battery now (not a grenadier).
I was wondering firstly how the starter got down to 70% and the auxiliary to 30%, and secondly how the IA system showed 78%?

 

[Lollo050968]

OK! Yes 78% is the precisly Ineos Software….Monitor will show only starter battery…. 70 to 78% both systems will have tolerances

I'd be happier if INEOS simply adapted their existing software to incorporate an extra SOC (state of charge) for any 2nd battery fitted - their seems to be plenty of room available.

You need to spend AU$200-300 for a battery monitor that will accurately calculate SOC, anything else is just a rough guide. Ineos will be using a basic shunt somewhere off the starter battery so who knows how accurate it is.

I doubt this is possible with the current setup.

When you say 'plenty of room' do you mean on the GUI (screen) or in the memory/code ?
What hardware is available to look at the state of the second battery ?

Einen Batteriewaechter mit Kontrolle ueber eine App zu installieren macht Sinn, wenn man sicher sein will, wie der aktuelle Ladezustand der AUX Batterie ist.
Ich habe zur Zeit einen 1.5 kVA Wechselrichter (230V AC) an der AUX Batterie angeschlossen, um einen 600 Watt FM Broadcast Sender kurzfristig zu betreiben.
Nach ca. 30 min ist die AUX Batterie relativ leer gesaugt, es fliessen ca. 100 A auf der 12 Volt Ebene. Die Abschaltspannung ist im Wechselrichter-Monitoring auf 11.9 V eingestellt.
Nur mit dem Smart-Pass alleine braucht man ewig, um die AUX Batterie annaehernd auf 80% mit Motorbetrieb und der LiMa wieder aufzuladen.
Mit der Installation des D250 (DC/DC Charger) parallel zum Smartpass geht es entsprechend schneller.
Um wirklich sicher zu sein, wie voll geladen die AUX Batterie ist, kommt man nicht um ein Spannungsmonitoring (Batteriewaechter) direkt an der AUX Batterie herum.

I think it would need a second battery monitor on the auxiliary battery.

The battery monitor, I think, is this thing attached to the negative terminal of the main battery:

@das mo which one did you install?

I went for 2 BM2 that someone proposed here. Cant find the post, but thanks for comparing some of the cheaper monitor!



Did not want to put lots of money on it for now, but only observe overall behaviour of the 2 measures in comparison to the Ineos one.

Seems the initial measures after install yesterday been off. After another 24h without moving the car, Ineos load status dropped 4 points to 74% whilst both monitors report stable 90% ish.





Meeting dealer in one week and hope collect some insight on system behaviour till then.

I'd charge the batteries first to float with a smart charger. You should be seeing this sort of correlation between voltage and state of charge when batteries are at rest, i.e, vehicle has sat overnight.

There is obviously some disparity between the voltage and the shunt, which leads me to suspect that whatever is draining the battery is not connected through the shunt.

Can you explain that some more, I'm not understanding.

There seems a huge disparity in what the actual voltage readings mean?

The battery monitor reads 12.04v and interprets this as 91%, green, battery OK; but your lookup table (not dissimilar to others) would put that voltage at under 25%.

Am I seeing this right?

 

[MrMike]

The shunt reads the current going in and out of the battery, there may be loads not connected through the shunt so this is possibly why the voltage reads lower than the %

I'd agree with that ... i'd expect a light load (a clock for example) but nothing too heavy ??
@das mo what do you see if the cars is disconnected from the battery (ie take the red + lead off) ?

Morning.

You say disconnecting car from both batteries and them keep observing the two battery monitors?

 

[DCPU]

By the shunt do you mean the Ineos battery monitor connected to the negative terminal? If so how can loads bypass this, there's only the one connection on the terminal?

Isn't the % just a calculation/lookup table based on the voltage reading?

Yes, the monitor. There may be other powered items that are earthed to the body so not using the common earth. Yes the % is a calculation but in the world of SLA batteries this is way off correct.

There may be other powered items that are earthed to the body so not using the common earth.

So how are they completing the circuit back to the battery if not using this terminal?
