I was rather hoping that someone would be able to point me in the correct direction - so thanks

Hi Folks, apologies for hijacking this thread.

I have a MG 40Kwh pack, which uses CATL modules, so it is probable that the modules use the same sort of BMS. I cannot find much in the way of info on the battery pack controller, it has LOTS of pins, and a big SOC on board, so I am shying away from ...

I have been quite actively developing a system that would allow the reuse of existing bms slaves from OEM vehicles, as documented on DIYelectricCar forum.


Hi Tom,
I notice that you have worked on a generic BMS slave interface, the idea looks promising, however on github there does not seem to ...

To clarify some confusion: From what I know the torque app uses diagnostic communication, not the normal cyclic CAN messages. The diagnostic of a certain control unit runs over a pair of CAN messages, a request (from the diagnostic tester, e.g. torque, to the control unit), and a response (from ...

actually looking closer at throttle.cpp, it already averages the last 50 pot values

float Throttle::AveragePos(float Pos)
{
PedalPosIdx++; //next average arrray positon
if(PedalPosIdx >= PedalPosArrLen)
{
PedalPosIdx = 0;
}
PedalPosTot -= PedalPosArr[PedalPosIdx];
PedalPosTot += Pos ...

Ooh,
I would be very surprised if tesla software is not fail safe, dual pot pedals have been around for best part of 20 years. I think this is probably anti EV bs.

I had assumed that OpenInverter was built around using a dual pot pedal, the Web UI is configurable for dual pots, The Web UI also ...

I have been suffering the same issue. I have been struggling with the issues for several days. I was getting the progress bar stopping at regular intervals. I was still able to ping the VCU.
I think I have now solved the problem.
Disconnect the Canbus, this instantly fixed my problem. I think canbus ...

Hi Ted,

I just did my first Openinverter compile this very afternoon. From knowing nothing to firmware loaded took less that 1 hour.
I am assuming the VCU has a web interface, that allows you to upload the new firmware.

If you have a Raspberry Pi, it's a doddle

A very quick howto - assuming you ...

Hi Roy,
After further poking about and reading Damien's code, I realised my error, years of using Torque on various cars, I had not realised that Torque was seeing canbus messages that were in response to requests sent from the car VCU, ie in most cases it just snoops on canbus activity.

I have ...

Further investigation by dumping the can messages using a Hobbytronics canbus device, I do not get RPM messages.
The only messages I see on the canbus are:
0x0120
0x011A
0x01D4
0x01DA
0x01DB
0x01DC
0x050B
0x055A
0x055B
0x059E
0x05BC

As far as I know RPM messages are sent out at 100ms intervals, and ...

Hi I have Zombieverter v2.15 installed and attached to a Leaf inverter and EM57 motor.

I am trying to connect to Torque Pro running on an Android phone via a wired OBD-2 connector and a Konnwei BT adapter. The LEDs on the adapter flicker, however I am unable to get RPM data.

It seems all can ...

Thanks Marty,
so it looks like I have everything pretty much correct, I am switching pin 18 manually to 12V
With respect to ZV CAN pins, I have tried using both CAN1 and CAN2
is the following correct?
43 CAN1 low
44 CAN1 high
for testing I have set UDCSW 0v

I am still stuck at opmode 0

By ISA ...

Hi I have a leaf Gen2 motor/inverter.
I am currently trying to configure the system using a bridge rectifier which delivers 330 vdc, manually switched on via 2 toggle switches.
I have not yet got any form of HV volt/amps measurement, I intend to use a shunt + arduino.
I ...

thanks M
I guess that would be the the 2.00A release from 7th May 2023, it's gradually becoming clear.
I am months off buying a battery, so I am concentrating on getting all the low cost bits sorted, I would hate to spend a lot of effort on designing around using a PDM and zombieverter then find I ...

yes good idea

A very good start on using a full Nissan Leaf stack can be found in the following thread

viewtopic.php?f=39&t=2928

Doh

found it
https://github.com/damienmaguire/Stm32- ... 32_vcu.bin

Hi,

is the bin file available, I cannot find one in the Git repo?

Hi Ali
thanks for the response.
Yep there are lots of topics on the Leaf PDM, and lots of rabbit holes. I eventually found a usefull thread.
..
I had already looked at the Zombieverter VCU Wiki, it says that it supports the PDM, but no further info.

Hi,
A quick intro
I am converting an Alvis TE21. The project is making good progress, I have a Leaf Gen 2 full stack including the control wiring and the HV loom. I have a Damian controller, I am using a Mazda MX5 gearbox, and have it mated via a Brat coupler. All good so far.

Now its time to ...
