Slow charged last night using my 16A portable EVSE before going camping today and I've been meaning to try and work out the battery capacity.

Started at 48% according to app, and when I checked the EVSE it had used 26.6kW... therefore to charge from empty would be 55.417kW but that's before any losses. Does anyone have any idea of what % losses would occur using an EVSE and the onboard AC-DC charger?

FWIW I've measured 92% efficiency when filling my Ioniq 38 kWh on my domestic 7kW EVSE, and I got a similar efficiency when I had an iD.3. So I'd expect you to get there/thereabouts as well.
