Tutorial On - How to build kit for 3 Phase - Mennekes Plug
OpenEVSE Support
I am not sure there is enough difference to make a whole new guide. For single phase the difference is only the Physical Plug. You can follow the current guides without modification. The guide does not specify the connector on the end, just the conductor connections. https://openevse.dozuki.com/Guide/OpenEVSE+40A+Standard/8
Connection J1772/IEC Type 1 Mennekes/IEC Type 2
Relay Out Hot L1 Hot L1 Hot
Relay Out Neutral Neutral Neutral
Ground Ground Ground
OpenEVSE Pilot Control Pilot Control Pilot
For 3 Phase all the connections in the guide are the same. The 2 pole contractor is replaced with a 4 Pole. L2 Hot and L3 Hot just pass through the additional polls of the relay IN and OUT No connections to the OpenEVSE controller are required. The connections are:
Connection Mennekes/IEC Type 2
Relay Out Hot L1 Hot
Relay Out Hot L2 Hot
Relay Out Hot L3 Hot
Relay Out Neutral Neutral
Ground Ground

While using a 3-Phase Input supply to the, does the output voltage to EV from Kit is 420V or is it 230V? If 230V: Then why do we really need a 3-Phase kit?
OpenEVSE Support
The OpenEVSE controller controls the relay on or off, it does not change the output in any way.
Output will always equal the input.
1 Phase with a 2 pole relay the EV will see Hot to Neutral or 230v.
3 Phase with a 4 pole relay the EV will see Hot to Hot to Hot and Neutral. Hot to Hot to Hot measures 420v.
In both cases the OpenEVSE controller is powered by a Hot and Neutral.
what about with the PP terminal. I have an BMW i3, from EU and i already connected but doesn't work. No charge nothing.
All three phases + neutral must go through GFCI coil.
If you are measuring current, then just one phase through current coil. Note that this will report 1/3 of actual energy when charging on 3-phase.
I'd be really interested in building a 3-phase version which can actually measure 3-phase consumption relatively accurately. I'll post another topic on this :)
@Ignacio, assuming you have the LCD screen, what does it say when you connect to your i3? Does it say "Connected" or "Ready" ?
How to properly take into account the consumption of the 3 phases?
OpenEVSE Support
The build is the same as Single phase with the addition of L2 and L3 on the contactor.
For Energy consumption you can upload the 3 Phase version of the EU firmware.

I think in this scheme AC TEST 1 and AC TEST 2 must be connected not at L1 and L2 but at L1 and N (240 V between them)
I did this scheme but it doesn't work
- OPENEVSE
- I've a RCD breaker to protect it and no GFCI protection.
- the GFCI test is disabled
- tethered cable + Mennekes
- PP wire is not connected
- Firmware actualized to 3 phases: openevse-3ph.hex
it doesn't work because the AC RELAY 1 & 2 has no tension and relay doesn't connect
When the car is unplugged display says READY and CP tension is + 11.58 V
When the car is plugged display says CONNECTED and CP tension is - 4.56V
When the car is plugged and Sleeping time or Paused, display says CONNECTED and CP tension is + 8.95 V
any idea to make it work?
some more information bout my problem

People around globe admire OpenEVSE kit but in Europe and many other countries, mennekes type plug is used. Anyone can help me out with a brand new updated BUILD GUIDE/ TUTORIAL on how to build an IEC 62196 - Type 2 (AKA Mennekes),1 Phase and 3 Phase plug?
