I made something very similar using two USB can bus interfaces and a python script to bridge them together. It decodes a lot of the data from the Nissan Leaf battery and allows you to modify frames on the fly. This sort of tools is very useful for reverse engineering! See...

I haven't really looked for a way to stop charging once it is started, it's possible Nissan did implement something but if they did, it's going to be reasonably hard to find because it isn't used by their Nissan Connect system. Jamming the CAN bus will probably stop charging but I'm not really...

My car has the 3.3kW charger and I have the charge timer turned on. https://carrott.org/pcaps/2016-24kWh-ev-plug-in-charge-timer-causes-sleep.pcap records what happens when you plug in. I believe the EV system and charger activate briefly and then it all goes to sleep...

The OVMSv2 hardware & Leaf support has been very reliable for me. Unfortunately this hardware is no longer available. The v3 hardware is nearly finished. I have a prototype and have ported the Leaf support over. The v3 platform is much more capable but not quite stable yet. I believe the v3...

Advice from the manual not withstanding, It is possible this error will put the inverter into a reduced current mode. I guess you'll need a battery capable of high current and a motor dyno (or a vehicle) to test this.

I've added support to emulate both the new and old TCUs with the OVMS v3 hardware, based on a configuration option. The v3 hardware has 3 CAN transceivers and is connected to both the EV and Car CAN buses so I select which bus to send on, and also what to send. See...

Nice! It's simpler than I was expecting. It looks like the constant values you're sending are just from the middle of my recording when I was driving the car. I wonder what they mean? I guess it's some variation on "all is well". It's possible there is a current limit and maybe even a voltage...

What happens if you filter out the inverter messages from my capture and then play the rest of the car back to the inverter? I'd expect these faults to go away and be replaced with new ones related to the start up sequence. I once played a recording of the EV bus back into a running car, that...

Let me know if you need anything else. The convert to canplayer binary python script I linked to you should give you a starting point to convert to what you need. Reversing this way is certainly possible. Looking at the LAN and TMS sections of the manual it does look like the inverter...

I made a capture from my car. I have a 2016 Leaf which is a little different from the 2013-2015 Leafs but hopefully this part hasn't changed. https://carrott.org/pcaps/2016-24kWh-ev-on-drive-park-off.pcap What format would you like? I normally use pcaps to store my recordings and wireshark or...

I captured some frames from my TCU idling (I can't get it to do anything else) and ran some experiments based on what worked on earlier cars and ended up with the following which works on my 2016 Leaf: 0x56e 4e 08 12 00 # Enable Climate Control (thanks Mitchell) 0x56e 56 00 01 00 # Disable...

Thank you Mitchell! Moving from the EV bus to the CAR bus and adjusting the 0x56E message as you suggest works! I've been tied up porting the leaf support to the new OVMS v3 hardware and only recently got a chance to sit down and test your advice. OVMS v3 has more can bus hardware so the only...

I've only tested on Japanese Domestic Market cars but so far the remote climate control has worked on all models prior to the 2016 model year. Models with Carwings or Nissan Connect need to have the TCU unplugged as this interferes with the OVMS's attempt to replace the TCU messages. Models...

Hi all, I've found that the OVMS remote climate control activation does not work on a friends JDM 2016 30kWh Leaf. The OVMS sends a message on the EV bus with ID 0x68c and payload 0x00 to wake the car up, and then it sends 0x56e with payload 0x4e to turn on climate control. This works on Gen 2...

Some Gen 1 cars require a wire to be toggled to 12v to wake up the system before you can send commands. I unplugged the TCU on my Gen 1 Leaf and connected the OVMS to it's plug to access the EV system activation request signal. See...

I spent some time with a friend's Gen 2 Nissan Leaf and got to the bottom of why the remote climate control works on some cars and not others. It turns out that if you have CARWINGS (now called NissanConnect) hardware in your car, the Nissan TCU module sends "Status" (0x4e) and "Idle" (0x86)...

You can wake the car up and start the climate control by sending a frame or two on the EV CAN bus, see https://github.com/openvehicles/Open-Vehicle-Monitoring-System/blob/470af78c4b9315da0062d2fa2bc5d3fdd7561822/vehicle/OVMS.X/vehicle_nissanleaf.c#L405 which implements remote climate control in...
