I posted this over at TMC but thought I'd ask here too:
During the week I charge at a parking garage in the city. They installed a 120v/12amp plug for me. All week it worked fine, charging at the full 12. Then yesterday it slowed down to 5amps. And what its showing is 5/5, meaning its only trying to charge at 5 amps. I took a trip today and the valet plugged it back in, and again it is charging at 5/5 amps. So it has "memorized" the lower setting and is not trying to charge at a higher rate.
I assume it lowered the rate because of some kind of power surge or brownout something?
If this continues to happen, it is an unworkable situation for me. I can't be continually visiting the garage to reset the charger back to the full 12/12. (Which itself is very slow but ok for me because I mainly use the car on the weekends and can charge all week.). So a couple questions:
First, any idea what might be wrong? Am I right that it probably happened due to a brownout or something?
And secondly, is there a way to reset it to a higher attempted amperage without having to visit the car every time? Ie, with the App?
Any other thoughts for me?
Meanwhile, don't know if its related but the car also was resetting itself to a lower amperage at my own 240v outlet at a home upstate (from the usual 40 amps down to 32), although Id thought that was perhaps due to a very hot day.
This whole "memorizing" of the charging rate at a given location isn't doing me any favors at the moment.[/QUOTE]
