Controlling the Leaf Inverter on its own

[NiallDarwin]

Great work going on here. Thanks for sharing

I've been working with a plug'n'play module from http://www.thunderstruck-ev.com/dilithium-vcu.html. It goes great on a G2 motor inverter but only in reverse on a G1 (I haven't ruled out wiring harness mistakes but I'm 95% sure I've done it right). Do any of you have data from a G1 and G2 inverter to share and compare? I'm interested to see any differences that there might be.

Here's my rig going:

Very cool! That is quite nifty indeed.

I've been using my DIY inverter controller now for over 4000km in my project. It works well with full power and torque available.

I've been asked about certain additional details about the inverter protocol (by email, mostly), so I went and added some to here: http://productions.8dromeda.net/c55-lea ... tocol.html

Here's some snow drifting, because of course:

Awesomeness!
There's so many of those stinky Estimas stinking up NZ, what a good use of them!

Amazing work!

So the Canbus messages the DUE is sending is enough to convince the Leaf controller that the rest of the car is there and working?

I have seen a few videos of people struggling to get the drive running due to not having every ancillary box attached? Or is that only a problem if using the Leaf VCM? The DUE is basically replacing the VCM?

Hello,

I have an inverter from the 2018MY LEAF, and I would like to try to install it to my 2013MY. Do you know, if the motor power is preset in the VCM or the inverter? Currently I have the 30kWh VCM, but the question is, if I install the 2018MY inverter, to the 2013MY, will I get 150PS?

Kind time!
I want to implement a counter algorithm from 0 to 3. E celeron55 on the page has an algorithm of 0x07 | (counter < < 6), but I cannot implement it. How do I write the code correctly?

[nlspace]

In the setup section of your code, define an integer counter, eg

int k=3; [This initializes the counter.]

then in your main program you can increment this counter and adjust it such that you can use it's value as the data field in the PID at the byte location.

k++; [This line increments the counter.]
k=k % 4; [This line adjusts the counter to be a value from 0 to 3. (% gives modulus remainder)]

Put your code to write the data field:
PID_number[data_byte_field_number]=k;

e.g. if using PID 0x11A, the counter is in data byte field number 6 or 0x06
so you could fill that byte with a line in the main program such as:
0x11A[6]=k;

Good luck and keep safe,

has anyone used the circuit board from " openinverter.org"?
https://openinverter.org/shop/

I have one and now I want to go back and use the oem vcm because I want to use the oem charger.

maybe I am overlooking something .

my project is an electric boat, and I want to delete the park motor. anybody else done that and what are the CAN messages I need to spoof for the absent park motor?

Hello, I am part of a student racecar building team called Armature Racing (http://www.armatureracing.com/, and we are using the Nissan Leaf 2012 inverter, motor, and battery in conjunction with Damien Maguire's code (https://github.com/damienmaguire/Nissan ... Controller) for the Arduino Due to control to inverter. Today, we have tested sending torque commands to the motor. The torque commands were successfully sent, but did not spin the motor at all, and a speed of 0 RPM was reported by the CAN messages. Furthermore, a high pitched squealing sound started emitting from the motor, indicating that the motor is stalling. When applying higher speeds, this squealing sound only became louder.

We have the Nissan Leaf gearbox (set 7:1) mounted on the motor, and I believe that the static friction from this gearbox is what is causing the motor to stall. Force is being applied but there is no rotation of the axle to be found. The torques we tested the motor for were between 0 and 400 (on a scale from -2048 to 2048, seeing as the inverter requests a 12 bit torque). At 400, the squealing became loud enough to where we felt concerned and immediately stopped.

Does anybody have any advice or information regarding these issues? It would be much appreciated.
