I have a Zappi type 2 charger installed and recently borrowed an eGolf, which was a pretty good experience.
Something I learned was the eGolf could vary it’s charge rate as communicated by the Zappi charger. So, for example, I could select the charge to be 100% green so if there was say 1kW of solar surplus the Zappy would tell the car to charge at 1kW.
When I recently replaced my Twizy charger I noticed an additional connection to the power lead.
This is connected to a pilot terminal on the charger circuit board.
My questions are:
Does anyone know what this pilot connection is for?
Does anyone know what happens to this extra wire in the power cable?
As I understand it the type 2 charging sockets have two pilot pins; one which tells the charger the vehicle is connected and another to communicate information including the charge rate.
It would be great if the Twizy charge rate could be controlled this way as it’s not often we have the full 2kW of solar surplus.
Alternatively if the charge rate could be reduced manually somehow, that would be useful.
Any information would be much appreciated.
