Ah ok Well in that case, nice and short solution then

[hubert]

CAN GND is needed. If your interface works without, that means there is hopefully a GND return somehow through other wires, like common grounding, but this is unreliable, generally speaking. A bit like running IC power lines without decoupling capacitors. It may work sometimes.

Please understand that CAN-H and CAN-L are signals referred to GND. Their opposite phase helps eliminating common mode transients induced in long wiring harnesses. It is not a floating signal going through decoupling transformers.

Really cool thread. Neat to see just how far people have taken the DIY solution since I posted up a meanwell stack with tons of help from DocBass and team.
I never used CAN signals as the RSP's would simply throttle down as they got to the set voltage so I didn't think about it as they were set bellow battery max.

Has any consideration been given to condensation or making an enclosure which wouldn't allow water intrusion ?

I still use my RSP2000 stack when at home and when it is nice outside but with my Diginow SCv2 coming soon I likely wont use it given the problem with water / rain / moisture.

Do you guys crimp or solder the Mennekes plug? The connectors look pretty heavy, so I fear crimping will not be easy. But I'm not so experienced in crimping. Soldering, on the other hand, may damage the black plastic on the end of the connectors, as it needs probably a lot of heat with the large steel areas.

I clamped the Mennekes pins in a rather large vice, which dissipated the heat from the plastic tip end, and soldered with ~60 watts.
Take care to not forget any of the plastics where the wires have to pass through.... I needed to re-solder a pin because I found out I forgot a retainer somehow
Also take note the PE pin has no plastic tip to ensure it gets connected first...

Good idea. I will emerge the plastic tip into a glass of cold water, while soldering the other side.
Crimping really looks a bit of close to impossible to me without very specialized tools.

For those who have not purchased their mennekes plug yet and also have trouble getting crimping tools, there are also screw type type 2 plugs available

this one is 3 phase 32A with screw terminals

i have ordered 15 new ones. Same Layout. i need soem also for my FP2.
should arrive this week.

This EVSE thingy might be an interesting addition to everybody's flatpacks: http://www.fivari.be/indexEN.html

I'm considering buying one for trips to less EV-friendly countries.

So, that actually worked not too bad. I heated the pins with a heat gun and used in parallel my 35W solder iron. I was able to fill the whole pretty well with solder (and the cable fo course). So, I hope it is sufficient for the high currents.

So, I now have a 3m cable attached to the Mennekes plug, and I wonder if I should shorten it. I don't think it will fit in the "frunk" area?! What length of cable do you guys prefer?

[Skidz]

I used to solder Bullet connectors to my 3 phase motors used in model helicopters, stowing over 250A... I'm not too worried about the measly 20A my Mennekes will push out at 4kW per phase...

And at what Voltage do those birds fly?

And at what Voltage do those birds fly?

Probably 10-20V DC, I would guess.

[Skidz]

22.2v and 44.4v (6s to 12s). Especially the low voltage machine used a lot of current... The HV setup ran at a max of 80A. The batteries were DC, but the motor used were brushless AC motors.

But only very few seconds at a time.
