A buddy swapped his EVSE Upgrade unit for my stock L1 unit plus $100. I tested the unit a few weeks ago by plugging it into my 120V at home and it worked correctly. I only tested it for few minutes and didn't let it go for a few hours.
I L2 charge at home and work and have only used my L1 charger once in the past year. My plan for the upgrade unit was to use it at my mom's house, which to is about 65 miles away, by plugging it into her dryer plug. I might only do this a few times a years so this was an inexpensive way to get into this.
Yesterday I made the journey. All seemed good at first. The car was charging normally off her dryer connection. When I checked back an hour later the dash lights were off. I unplugged the connector from the car and plugged it back in. Charging continued. After about another 10 minutes the car stopped charging again. I could not get the car to charge any longer. I switched to the L1 connector and it would not charge off that either. Nothing amiss on the EVSE LED lights. All normal.
All this time I still see the charging icon on the dash, so the car could see something plugged into it.
Luckily there are a two good L2 charging options at my halfway point. I prepared for this test run by charging there on the way down in case I ran into any issues a my mom's house.
I'm charging with the EVSE Upgrade unit as I write this. 45 minutes later it's still working.
Since we made the unit swap my buddy's Leaf was hit and totaled. His unit has a lot of use on it and the cord is pretty twisted. I'm thinking of just swapping back and having my unit upgraded. I don't feel I can trust the unit now.
Any ideas of why my car might have refused to charge off it yesterday and if I could have done anything?
