Tutorial On - How to build kit for 3 Phase - Mennekes Plug

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?

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.

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

Control Pilot             Control Pilot

Thank you man. (Y)

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? 

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 would be really nice though would be a way of identifying when there is three-phase power used so that any current measurements could be taken into account. I'm not sure if this can be done with the existing hardware. Sure, you could multiply current / power by 3 when using three-phase, but how would the unit know when to do that or not?
