I have written some new code to update my existing basic vcu built on perfboard! This new version takes over throttle and regen input duties so I can transmit them to the 2 oi boards using the latest and safest firmware, it also incorporates al my rx8 dash functions and does motor/gearbox speed ...

I should know the answer to this as i've been here before but my notes don't record this...

Which of the DC in connections on the Outlander rear inverter is the positive ? I think its the left hand one (i.e. next to the motor wires) in this picture as this has the 30a and 40a fuses on the two ...

I want the sound of a horse trotting as my sound generator. It's on my to-do list but quite close to the bottom.

I had to get the real thing so i could be sure which comparative sensor i will buy to replace it in this VW Cupra battery. I am not sure what kind of sensor is in there. I need a way to test the OEM VW sensors inside the battery too. Thanks for the model.

Here you go:

No that is not Volt Gen1 battery sensors

I just got one sensor from a friends Gen1 battery.

I connected my Fluke multimeters temp probe and measured three stable temperatures
It seems as this is 10K NTC thermistor with a sensor B ...

Still for sale...

I want to imitate your setup first time to avoid running into the same problems, I found this and looked on the wiki but didn't see anything new, did you end up writing about it yet? Maybe some kind of napkin schematic? TIA!


Good to call me up on it.
With Mazda MX3 now i dont have that problem ...

I need temp curve data for Chevy Volt gen1 battery thermistor values. Does anyone have either data or thermistor model or PN?

tnx Arber

I've been using the ESP32 in my Zombie for a couple of weeks and so far so good.
I haven't seen any communication errors since installing it and before they were frequent so I'd say this is a very worthwhile upgrade.


Anyone tried to use this with Tesla charger gen2 or 3 board? Would the UI ...

Can someone explain how I can implement a (2000psi, 0.5 - 4.5v) brake line pressure sensor to increase regen in parallel to brake force, in the zombieverter.


Thanks


Why complicate with pressure? You could use linear pot 5K to return 0V to 5V signal. You put this under your brake pedal ...

I can confirm receipt of one gen3 charger... single phase wired for 3phase connection and modules rewired.
Nice silicone wire harness added and clearly marked. see photos

I must rate this product 5 of 5. Also shipping in EU was very fast.

Hi,

Thanks for the reply,

I just turn it manually by hand , I have not yet made the motor run as i am still making the encoder mount.

I am actually using mlx90380 ( magnet encoder), i think its an evaluation board model. I have checked the datasheet but i cannot find any details on setting ...

Ah your chip could be set to different pole setting. Leaf motor is 8-pole, 3-phase, 48-slot machine. Could be that you have a 4 pole count set in chip and ...
Or you have FOC set incorrectly?

Read the datasheet if there is a possibility to set pole count on resolver chip.

It seems like a and b channels is readding it but I am not getting full 0-360 rotor position using encoder . I checked encoder ground to pin 22 and 23 of MCU, pin22 is reading 1.3v while pin 23 reading 4.9v is it normal? Any guess what's causing this?


Best regards.


so are you reading A and ...

I did not take any action against the native processor, it remained in its normal location.
current sensor amplifiers for the O.I. board = 4.11

They usually are powered from the HV side and require modules connected to work.

Or atleast thats how the ID3/4 MEB slaves work.


Yes i did connect cells to BMS from the orange cables. That was easy. But when i connected 5V and 12V to the other side of the circuit barrier i got 0.1A consumption ...

OK now... where were we...

So i read the pinout on the 24S module. Its straightforward thermistor followed by the negative most contact for supply and then by sensing contacts.
I put the table from my notes to PDF.

Hi guys

I have a Golf that has been converted to electric. We have changed the batteries to 48 LifePO4 cells of 3,2 volts 100ah (approx 15Kw) in series. Where can i find a bms and cell balancers for this configuration?

Secondly can i make 3 banks of 16 cells each (each bank will have it's own ...

Hm... my idea was not to make another forum but rather unify one topic at Electric Vehicle Topics and collect knowledge there...

I just bought a Chevrolet Volt Gen 2 Charging Port 24278118

It was a gamble buy as i only saw a similarity between Gen2 charger AC connector and that made me think both the extension cable and Charging port use the same type of connectors ...

I'll need to edit out the stuff for the charger, compressor, and heater. None of that will exist here. Maybe throw in a charger at a future date but I have other ways of charging the pack for now.



No need to edit out components for first tests. They will just not populate those variables ...
