On New Year’s Eve, 2012 I was charging at a public Blink charging station while I was shopping. I was telling my friend how the EVSE will text me if there’s any issues (like charge port overheating), so I don’t have to worry about my car. After about two hours, I decided to check on the charge status using the HondaLink EV iPhone app. The car had stopped charging after about 30 minutes. I tried to restart the charge through the app, which has always worked, but this time it didn’t. We went back to the car and the Blink EVSE was no longer activated to my account, and seemed to have forgotten that my car was connected at all. I plugged into an adjacent Blink and was able to charge up enough to get home.
However, once I arrived home and plugged in the car would not charge. The dashboard lit up with error lights and four different error messages came up on the “multi-information display”. In the past, an unplug and re-plug has started the charging. Unfortunately, that didn’t work this time. I had enough juice to try three separate charging stations and none of them would charge the car. By this time, I didn’t have enough power to make it to the dealership, so I had the car towed.
After diagnosing the issue, Honda determined that my Fit EV needed a new “controller”. After some research and more info from the dealership, I have learned that the controller that was replaced is called the “battery condition monitor module”. The BCM, which lives under the passenger-side dashboard, takes care of the charging commands, among other things.
Unfortunately, Honda didn’t have any BCMs on hand and didn’t have a lead time. They didn’t know if it would be days, weeks, or months. About a week and a half later, I got a call from the dealership telling me that the car was fixed and to come pick it up. Unfortunately, as I was on my way to pick the car up, they called me again and said, “never mind”. There was a new issue, which would end up requiring a battery pack replacement. Details to come in my next post.
