Yes, I am interested in these parts, I am also located in NL.
Stuur me even een DM.

Please drop me a DM so we can exchange details regarding shipping etc.

I have a couple of boards available. They work with Arduino. All prototypes, but functioning never the less.
If anyone wants to experiment with them, just let me know.

The next iteration will be able to run CircuitPython as well as Arduino, and will have small improvements.

PaulHeystee

The first boards just arrived.

For now I have set these specs: The controller: ESP32 - S3 mini I/O: - 5 digital outputs (9 to 16 volts) for relays, LEDs etc. - 1 analog input (9 to 16 volts) for variable input (heating level) - 3 digital inputs (5 volts) for gear switches or any other switches - voltage output (5 volts) to power ...

Here is the 3D model of the interface-controler

I will post my updates and photos here. Any feedback would be great.

I am building an interface between Nissan Leaf CAN and, in my case Saab i-bus CAN. I came up with the following specs: 3 x CAN bus 1 x LIN bus 4 x 5 volt input digital (analog with mod option) 5 x 12 volt digital output (to drive relays or dash boards lights) 3 x PWM output at 12 volt (battery volta...

April fools joke?

The link does not work..

Interesting, GBP 300.000,- sounds a lot for a working prototype. We built a working prototype EV based on a Daihatsu Rocky 4x4 for less then 1/3 of this, including my time spend developing it. We used only standard Nissan Leaf components without modifications (to the circuit boards etc). We got the ...

Its is gen 3, from a 2019 110kW Leaf (I assume that is gen 3), sorry for any confusion. Maybe gen 2 is the same, I have a PDM from an eNV200 (don't know the year) maybe that is gen 2, if so I will open it and have a look. Hi, From what I know the Gen2 PDM is capable of doing the Chademo communicati...

Paulheystee, that schematic, is it for a gen1 leaf? It doesn't seem to match up with the pdm wiring I Have for my gen 2.

Leaf Gen2

hi, I have no clue. Nothing comes out and nothing what I sent in works.
I guess I bin the heater and find something else.

Hi, yes I need the wires and connectors. I want to check out the original controller, to see if I can persuade it to work with the rest of the components.

yes

Please see the picture of the controller below:

I am looking for the two 60 pin connectors that go onto the original Nissan Leaf motor controller computer.
Does anybody have a wiring loom with these connectors laying around?

PaulHeystee

Hi EvSteeve,
From the Leaf schematics I can see that the Chademo is fully connected to the PDM,
Please see attached print-out of that page.
The PDM is connected to the CAN bus (and other components)
If you have any questions, please let me know.

Hi, I have some trouble setting up the LIN communication software and hardware. I am working on a small controller to manipulate the dashboard gauges on my Saab 93, for this I use CircuitPython. I like to add the LIN bus with a MCP2021 but I have no idea to setup/build the correct LIn message string...

Hi, please check attached picture

PaulHeystee

see here the page from the Nissan Leaf book.

Hi, yes, it is an SR motor, Switched Relucatant motor and needs a controller that reads the hall sensors in the motor.
I am working on such controller because I need one in my Saab 9-3 cabrio, which has a full Leaf stack.

On the Leaf this motor is controlled by the VCM.

PaulHeystee

Hi Chrkly, Thanks for your input, yes, with that kind of power already coming from the L210 it make not much sense I guess,. I was just thinking, the ICE is there doing something (charging the battery I guess), why not replace that with an electric motor, but if it make things over complicated it mi...

PaulHeystee

Hi, I have a question; would it make any sense to add a 3rd electric motor, like a Nissan EM61? Mounted where the ICE was?
I can imagine that it will be added power to the drive train and perhaps by controlling various motors in the system make it more efficient (?)
Anyway, just a thought.
