Easy dilemma to solve, look at the charge curves & notice that there’s nothing in it between the ID3 & the Kona, the Kona being a little faster to charge due to a more aggressive charge profile.

Also not this “Unfortunately it is not possible to use Autocharge with a Volkswagen ID.3. “, now this is about Fastned & as of yesterday, Gridserve, where you plug your car in & it recognises your car (from previous charging on that network) & starts to charge without needing to mess around with cards & pressing buttons. So, it looks like the Kona can do that but the ID3 doesn’t as it doesn’t use the standard CCS handshake (remember that VW are pushing their own Ionity charge network).
