TC MAX Charge Socket Pins

Hello guys,

I'm converting my TC MAX to be able to charge on these EV Charging station using Type 2 socket (Regular charging port for cars in EU).

I got a 20a 83v weather sealed charger which will be installed somewhere in my TC MAX along with a Type 2 EV socket. I'm using 2 batteries in parallel, in theory it should split the amperage between the batteries if they have the same AH.

Type 2 socket has similar features compared to TC MAX socket.

CP and PP is the one I'm looking for from the TC MAX socket.

PP - won't let you ride your bike while charging.

CP - signal back to the charger to allow charge, or something like that.

Does anyone know what is each pin from the TC MAX charging socket?

I could not find a wiring diagram for that socket.

 

I also made a video, of my project (sorry in Portuguese)

Thanks in advance.

PP - is for measuring resistance.  Check this: https://www.picoauto.com/library/automotive-guided-tests/charger-vehicle-proximity-line-resistance-type-2/

CP - there is much more what is going through this contact.

i.e.

-PWM signal from charger to vehicle

-voltage signal from vehicle to charger so charger can see the status of vehicle

and some more

You can activate the charger via the pin circled in the photo. Once it’s been activated the pin is no longer needed and the charger remains charging until it’s switched off. Reckon this is your CP signal pin. 

I haven’t worked out the others yet. There’s defiantly a PP signal which stops the motor from moving which I think is the pin just above the red circle in the photo but that’s not 100% confirmed yet. Still working on testing it. The other two I believe are some sort of data lines. Note I only have 6 pins so different to the 2020 Tc max if that’s what you have.

Thank you @LHK and @nereww. I'll make some tests here and share my findings in a video. Thanks again!

@rodrigoono so after a few tests and checking the wire routing I can confirm a few things

030D2BB1 081D 4313 96A9 E23F798EF247

Pins in green are what seems like a data line pair. The lines run through battery connector, charge connector, speedo and motor controller. Some sort of data communication between them all.
The red is to activate the charger to charge and the blue disables motor if the charger is connected, this wire runs straight to the motor controller. Hopefully that helps somewhat

@lhk thanks, Looks like red and blue can be used as CC and CP in this case. I just realized that I purchased wrong socket, I got a male one🤦‍♂️. The charging stations are also male. It will take a month or so to get the new one. 

Thanks again for your help.
