    Stand alone OBC/PDModule EV system Can 2015 - SOLVED

    Well sorry folks it only took 5 months to get back to testing this on my test bench. The good news is the python code works perfectly. Well done Cees and friend. Here is a really quick short sloppy video shot last night to wrap this up. https://photos.app.goo.gl/V3Tg3D5Xbc6FTkAx8 Note : when I...

    Stand alone OBC/PDModule EV system Can 2015 - SOLVED

    Conclusions on using a Raspberry Pi as an OBC controller. After a fair bit of messing about with different bits of hardware and software I was able to get some good clean recordings of the Raspberry Pi CAN data transmission and indeed with no other know tasks working in the background the data...

    In case there are others interested in the Raspberry Pi idea I thought I should provide an update so far. I managed to squeeze some time into getting as RPi set up with a Waveshare duel port CAN Hat. I have connected it to my Android DUE transmitting the CAN commands that would normally go to...

    Thanks lorenfb, All my work so far has been done on a Arduino Due and seems to work well that said there have been speed challenges with some other CANBUS EV work. I have also had the pleasure of using Muxans Bridge based on the XMEGA32C which definitely is up to the job...

    Hi, I have just started to scratch the surface on this and immediately found a few interesting remarks, regarding Raspberry Pi and Python. Regarding PPi.GPIO - If you need more accurate timing use bare metal RPi (which makes it work like a microcontroller), use a real-time OS with a better...

    No the code provided does not provide cut off as there are so many ways to do that depending on the battery pack and BMS you are using. I am actually using a nissan leaf pack and bms independently with an additional due that manages charging and uses the SOC to determine when to shut down. I...

    I have two of these here and one other that I used for data collection earlier on. I am pretty sure one of them was a 2014. The Toggle bit boards are great, I have used a number of them and have a canfduino board waiting to be used in my next project. If that is the board you ordered it has a...

    Hmmm, 2014 should work. I am wondering about the timing, do you have a way to measure the timing between the 10ms messages, the 100ms and 500ms to be sure that its right. You are sending one of each message sequence every 10ms ie 11a,1f2,1d4,1db,1dc repeat with next sequence repeat 4 times with...

    My only comment would be is that Jacks code is different from mine and there are many variations on the data packets that might work particularly regarding the output power ie charge current. In my case it pumps out about 16 amps. My code works in my car and others have also been successful in...

    There definitely are more values as the status of the battery pack changes and so reports other information that is not relevent to getting the charger started.

    Do you have the VCM and the BMS disconnected, you also do not need the inverter. If you have any of these connected you could get message crc conflicts as the message must be sent in a specific order. My code was designed to work with only the OBC connected. That is how it works on the Gen2...

    Code will not work with a Gen1 Leaf 2013 or earlier. The code was written for 2014/2015 which are Gen2 the charger architecture is completely different as well as the Can Messages. In theory if you can figure out the correct can messages by making a recording of a 2012 car that is working you...

    Thank you for the info. Stopping the charging at a predetermined voltage should be easy with a master if then else loop.
