Where did you obtain the SimpBMS from? I recently got notified EV-Shop has ripped off my board design and are selling them on without my consent.

Without load vs with load

Your CAN logs show the battery sagging down and thus the udcmin limiter kicking in, it kicks in before hitting udcmin as not to have an abrupt stop of of torque

We will need logs of Potnom from zombie will doing this, there may be things limiting the torque request as its not flat out.

Edit your issue is: "udcmin": 360

This is limiting throttle, this should be shown by zombieverter and the potnom spotvalue

This is high for a 96s battery, change it to ...

Okay, need to build a setup myself to go through some stuff at some point. To make sure I do not break anything, specially the contactor control in zombie.

I may have time this weekend or not.

It should be trying to pull IDC data too.

Ah thats right I taught the fix for blocking CANmap from grabbing same id. could have the SimpBMS code put it also in udc

What controls your contactors?

What is you Param::BMS_Timeout set to?

SavvyCan and a dbc file from Dalas github https://github.com/dalathegreat/leaf_can_bus_messages

Yes coolant plus batteries is bad and not really fixable.

No I wont post bins publicly. Let me reach out to you about testing.

IDC is a signed 16 bit value. no idea how to map this properly, I was hoping someone with a bit more CANmap experience would lend some insight.

So a high value above half the max of a 16bit value is a negative number.

Can ofcourse also map this hardcoded into the SimpBMS class in Zombie. All you ...

So you are saying it is not possible to map cab300 to zombie instead?


Possibly as its a 32 bit value with a large offset so might not be possible.

SimpBMS (note there are many versions of firmware) works with the CAB300(note there are a few options of this sensor), you just need to configure ...

Just select the inverter and it will work as this is a "normal" use case. Also mentioned else where before.

Again, have the SimpBMS which you are using read it and translate it to a signed 16 bit values in stead of the complicated 32 bit one.

This is a lot easier to map into the Zombie.

Yes you need to have it show up as volts not mv.

Simp BMS provides battery voltage and current. So map those to the idc and udc spotvalues/params

The I3 LIM code uses those params along with charging params. Params are a general table of values referenced by all parts of the software no need to link them.

No a CAB300 is not a shunt. it is a current sensor.

Just use the CAN map to get the values in there. you can even just use the CAN messages from the SimpBMS
params you just need to map are idc and udc

Your zombie is not doing precharge then.

What inverter, what motor, what board/vcu?

A decent power supply that can do 12V at like 5A is a good thing to have.

HV power supply, no point really for spinning a motor.

but dose not run the gen1 leaf charge

Where you getting this info from? I do not believe this to be the case.

Go post in a relevant topic and not randomly in other topics.

Flat only really.

Other positions can work, but have risks attached around venting or durability.

single cell beeing up or down balanced, they can only be bled down. this is the 12 bit value in the "0" message id

Also you have next to the cell voltage a signal that indicates the "quality" one of the values indicates voltage not to be used due to balancing.

Correct this is the limitation, it is all legacy code and being stretched very far and is breaking at the seams.

Cool, did you create a DBC for easy tracking of the newly found signals?
I cannot really find anything too "interesting" in the module.cpp

The Tesla M3 PCS is NOT waterproof, so I would re think its location and house it in something.

You need a start signal to go into precharge.

And you giving it a start 12V signal?

You can use the print function to save as pdf, or atleast you can for windows, easier to save.
