Okay I will let you be. I work based off measurements and graphs. Only this works in my experience, but you do you.

Just to clarify, does udc control charging or voltspnt. You implied that i was overcharging my batteries because udclim was set at 380 are you THICK.
Also despite the fact that you ...

I'd appreciate a log if you could still get one? Interested if there's a bug in the UI for scaling or if the SBox is reporting the funky values too.


I am convinced those values are because the car was at 260V as the earlier plots did not show the "funky" behaviour. But hey what do I know.
Its ...

I have listed this car before and have now decided to give up on it. See this latest post and replies to understand where things stand.
https://openinverter.org/forum/viewtopic.php?t=5640.
The car will go live on ebay tonight @ 19.00 with a starting price of £1000. https://www.ebay.co.uk/itm ...

Can you use savvycan on the bus the SBox is on and attach a log?


Thanks for the help Jamie. I am done with this. I am cutting my losses and moving on. I spend most of my time thinking and trying to resolve the problems I have had with the car.
I have wasted the last 3 years and god knows how ...

"You thick?!? This is taking alot of my energy and time dealing with you even though my instructions are very clear."

Thanks for that Tom please don't waste anymore of your time and energy on this.
It seems you don't even accept my word that the car has worked in high gear.

I will need to charge the battery up first.

Tom I am not sure what you mean you saw the earlier plots. ok there were no scales for you to see but they are completly different. Do you want me to record some spot values of me driving at 70MPH on a road somewhere? I am happy to do so if it puts your mind at rest.
How would you like me to proceed?

Just reading through the questions to make sure I have answered them all so far.

"How is the HV connected to the inverter"

Middle picture, +ve comes from the +ve of battery 7 in the rear and in via the isolation connector on the left then to the +ve of the sbox through the fuse throu8gh the ...

Ok I will do that in the morning.
Thanks for your help

Sorry I have described my hv connections from the charger.
The dc to dc comes out of the dc post of the charger and connects on to the back of the BMW fuse box

I have 4 batteries in the front and 3 in the rear should that matter?
I could disconnect the charger

I have an igniton input to a relay for running. I will have to look in the morning for the charge input!!!!

You got an ISA shunt and some better contactors?

Has the SBox ever been made to open contactors under load or no precharge?


The sbox is a relatively new addition. Which I think means you don't need contactors or shunt, the ones shown are for my chademo charge system (as yet incomplete ...

DC converter goes from the outlander dc terminals to the negative terminal of the disconnect unit and through a fuse to the isolated side of the positive sbox contactor.
DC charging is controlled by the zombie vcu and outlander canbus

contactors are for the chademo!

One thing to note is when I parked up i noticed the battery voltage was down to 260 which might explain some of the results i.e. sag.

When the car is set at 80% throtmax and just using high gear the car is quite drivable and I have probably driven 200 to 300 miles with no issues.

1st photo shows ...

Tested this afternoon,

The first 3 captures are at moderate throttle at throtmax 50% with idc 500, 600 and 700 and it is nearly impossible to pull away.

Last capture is at about 40% throttle position with the throtmax at 30% idc 700 about 20MPH.

Side note: the T-can seemed to keep connection a ...

Deep joy, forgot to isolate the 12v battery 3.6v left, slow charging with little hope of recovering the battery. Happy days!!!!!

"Where is your zombie mounted? I know too little about your build nor is there very little info on your build on the forum."

I will probably post some pictures when I am happy that everything is where I want it to be and when I feel it is the finished article.


"Possibly an external wifi antenna ...

Really struggling to get a plot using the wemos mini, as soon as I pull away I lose the wifi connection. This was the reason I tried to get the T-can working. Even with the T-can it was difficult but as I understand it the T-can won't work with 2.17A. Is there a way to connect via the serial ...

I understand about the photos I was just asking what parameters you need on the plot. This will be with 2.17A of course also what would you suggest would be Safe settings for udc and idc?

Thanks Tom, exactly which values would you like me to show and how do I know if they are using the left or right scale?

Is voltspnt what controls the max charge voltage then?

My batteries are 12s so 4.2 x 12 x7 = 352.8 volts this is what my charge is normally set to. Charging with outlander and zombie. BMS thunderstruck, probably not the best but I bought them 3 years ago when there were fewer options. Does UDC max and min only have an influence over charging?

I promise ...

Sorry just noticed the lack of pictures. Also now have udc and idc set to max settings. I will post the photos tomorrow as there is a nice bottle of shiraz calling to me

Will go back to 2.17 A 1st thing 2moro
