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.
@rodrigoono so after a few tests and checking the wire routing I can confirm a few things
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.
@lhk I tested today using 2 different ev charging station and it did not work. I tried switching the cables for PP and CP and also no luck.
Problem is, I can't find a wiring diagram on how to setup propelerly or trick the ev charger to release the voltage to my charger.
I'm now Back to the brawling board.
You can buy type 2 to uk three pin socket adaptors so that you can just plug in your normal charger to a charging station. I’m guessing there must be a small bit of circuitry inside it that talks to the stations CP signal and gets it to start outputting. Wonder if you can extract that circuit from it and use it yourself. I’m assume whatever signal super soco use between charger and battery is unique to them and not readable by a charging station
PP
put 1K5 resistor between PP contact and PE. This will tell charger to allow maximum 13A.
CP
use this scheme.
R2 - 2K7 - tells charger that vehicle is connected
R3 - 1K3 - tells charger that charging started.
When S2 switch is ON, charger will release the voltage.
I made this:
Thank you @nereww !! This is awesome! I will work on that circuit, seems to be quite simple! Thanks again for sharing that.
I will post some pictures and videos once manage to make it work.
Thanks guys !
@nereww sorry, quick question,
There is a diode in the diagram, what kind of diode did you use?
@rodrigoono it's a resistor I believe not sure how many ohms, but you can buy this already built from AliExpress now for around €40-€50.
It worked guys. Thanks for helping.
I made a video(in portuguese tho) showing the charging system hooked to an ev charge station. https://youtu.be/LAhmj8vTDmo
Cheers
