The plan is to use standard charging ports to allow 'Type 2' charging. This is going to require a suitable charge controller, battery management system and battery.

The charging port on our CUPRA Born is close to what we are planning but, it will feature a much more sturdy locking cover and much clearer indicator lights, to show what is going on. Note the plastic cover over the CCS port.

We currently have a MyEnergi Zappi EV charger installed at our home. This can charge at up to 7.4kW and is capable of using only solar power to charge and EV.

Rob has written a review of the MyEnergi Zappi charger.

The rate at which you can charge an EV battery varies with battery state and ambient temperature. Once you get over about 80%, the charging rate will reduce. In colder weather, this is even more evident. This screenshot shows the charging rate tail off as we charge our CUPRA Born to 100% on a cold night in January.

Fellten sell this HK-LF-540-14 6.6kW charger that can output 350V to 680V and 14A. It is air/fan cooled.
