Zappi 7kW EV Charger Installation

EEVblog:
Installing and testing the 7kW Myenrgi Zappi EV charger with the home solar system and the IONIQ.

Monkeh:
The 10% minimum is from J1772 - <5% you must disconnect, I think, obviously you want a little wiggle room around that. Car must respond to duty cycle changes within 5s.

FyKnight:
Yep 10% PWM duty cycle = 6 A current limit, the minimum per spec.
But 5% = use HomePlug GreenPHY powerline comms over the control pilot (on top of the PWM) to negotiate charging rate, including potentially DC fast charge.
I think below 2-3% = disconnect.

That'll be a newer addition from the IEC standards. The intention is to be able to communicate with smart meters and the like, which I reckon will never actually happen. On the sidelines, well, I'd be curious who has fingers in the Homeplug pie.

EEVblog:
This is how well it matches the solar production. Very impressive.




And you can see it automatically resume charging when the sun comes back out.
