I mostly charge at night so the outside temp shouldn't be too extreme but maybe my garage traps some heat. The charger current settings are set to Maximum. I haven't contacted Wallbox yet. These are all great things to try. Last night it charged all the way to 80% so..........I don't know what's up. I need to start narrowing down the possible issue. Changing the current settings to reduced might be a good next step to see if it makes a difference.Any additional parameters that you can share? When do you charge - experiencing hotter than normal temperatures? Have you contacted wallbox?
Also....what are your AC charger current settings in the vehicle. Per manual:
"You can adjust the charging
current for an AC charger. Select an
appropriate charging current.
ś If the charging process does not
start or abruptly stops in the middle,
reselect another proper current and
re-try charging the vehicle.
ś Charging time varies depending on
which charging current is selected."
