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.
All charging control will be achieved through the app.
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.
