First post, I purchased a used 2016 Eva that was layed down almost 99% cosmetic damage, like a grass slide.
Problem is it's been sitting for almost a year and the battery seems completely dead.
I tried to charge it at a public charge station but it wouldn't initiate.
I'm not sure if I was doing it correctly or if it's so dead it won't start charging, or if I need to check anything before I start.
Thanks, I am a motorcycle mechanic but very little experience with ebikes
Thanks in advance!
Is your battery SOC at 0? 0 miles of range left?
You could have better luck with a J-1772 charge. An AC charge avoids the initiation process by using the charger in the bike. Do you have the granny cable for the bike? Or a J-1772 that you can use?
CCS charging is rather picky during the initiation process. It will not start the charge if it doesn't like what it sees. IOW, out of range of what is expected.
What I am thinking is the voltage is too low for the DC initiation process but it could be okay with an AC charge. IAC, you want to get it charged ASAP, the longer you wait, the more likely it is to do permanent battery damage (if not damaged already).
The worse thing you can do to those batteries is leave it for many days totally discharged. But there is still some chance that it can be recovered.
