Here's a graph of my home EV charging data for overnight (Watts on y axis, time on X axis).
Home charger: Ohme
Electric tariff: Octopus Go Faster 2030 (4 hr)
Starting at 20:30 hrs on 27/1/2021 with 36%, finishing at 100%:
Type 2 vs CCS charging speeds

Ok, the reason for the changing loads was your local power management. But you was able to load with more than 7kW (with power management/old tariff), now it's about 6.5kw. Do you know the reason why the load is now reduced?
P.S.: 1.4kW from the old graphs is the minimum load of your charger (except zero) at 6A => 230V x 6A = 1380VA about 1,4kW. Less than 6A is not possible with AC charging.

An EVSE in simple terms is just a relay and a signal wire, the voltage of which is regulated by the vehicle and therefore determines the current that can be accepted. My electricity tariff & EVSE (Ohme) do not control the current draw, this as I have stated is dictated by the the vehicle.HausO wrote: ↑Fri Jan 29, 2021 11:18 am Ok, the reason for the changing loads was your local power management.

I also log the voltage & on the first set of graphs the lowest current draw was 5.16A (1289W / 249.7V)
On the more recent graphs, the lowest was 1.67A (415W / 248.5V)
Please explain or link an article to where it explains that it is not possible to charge on AC below 6A.
Here is the graph zoomed in on 27/1/2021 between 23:44 hrs & 00:04 hrs (Watts on the left y axis, Voltage on the right y axis & time on X axis).:

@londiniumperson: Sorry, it's not the minimum load, but it's the smallest maximum load that the wall box can signal to the onboard charger.

I have graphs for both rapid/quick (50kW+ DC) charging and fast charging (7kW AC)
Regarding rapid/quick charging, Bjorn Nyland tested the Honda e at Ionity 350kW.
Youtube: Honda e fast charging comparison
I've compiled a charging graph for the Honda e below using Bjorns numbers.
Notice that this values was in the summer at 29C.
For the fast charging graph I've done the measures my self with a Power Energy Logger.
I have a Honda Power Charger S+ hooked up to a 22kW/32A/3-phase circuit.
Download the whole Trend Report: Honda_e_7,4kW.pdf
Quick Summary: Start charging at 5% SOC all the way to 100%. Total time 4h30min. Tapering the last 30min. (see "End Tails" for details).

Here is a video of a charging I did in CCS 50kw. It's the second time I've charged at this location and it never goes beyond 35kw.
