chademo solar, relay

I want to build a little solar chademo charger
I have 5kW solar panels and the e-nv200 (same as leaf) with the chademo connector.
directly from DC to DC, no AC
first, how can I close the 2 relay to get the 400V on the chademo pin ?
thank you all

To get the relays to close, you practically need to fully implement a CHAdeMO charger. Physically you need a big output diode, voltage and current measurement, CANbus and a few 12V signals. Then it's a matter of implementing the protocol in software.

Take a look at viewtopic.php?f=17&t=763&p=10847

ok thank you,
so I think my idea to build the solar charger is not so bad, but I don’t find topics to make it !
at this time I only use arduino, but no power electronics !
