So, I was at the track and my bike was being a total bitch, not wanting to charge.
It'd time out, it's sit there in 'initiating'. sometimes it'd lock up and id have to fiddle fuck with the key for a few mintues for something to finally time out and let the bike shut off and reset, etc etc.
Tried my normal tricks of hefting the cable over my shoulder to drop straight in so it's not pulling against the side, nope, the push wiggle up, nope. Took a real good look and seen just a bit of dust in there, i dropped it earlier in the dirt, and thought i had blown it out good enough. i didn't.
so, a good cleaning with some alcohol and a prox brush. some of those prongs in there have center holes. goto the toothbrush section of the store, and they sell between the teeth brushes, kind of like tapered pipe cleaners. dip one of these in alcohol, and run it in and out the plug holes to get it all cleaned out, yep a little crud in there. You can also use the thing, one of the bigger ones to do the roundy roundy on the outside of the prongs too where you can reach to get the crud out of there too.
Even for AC, the main charging voltage is 115 VAC to 240 ish VAC. That'll push thru a bit of corrosion pretty easily. The pilot signal and the comms signals now, those can drop to as little as 3 volts. 3 volts is flea power, pretty much ANY thing can stop that from flowing, and if the signal gets attenuated, or worse, corrupted, which can cause a software lockup, now you have to play games.
Ive seen numerous complaints of charging issues, and wanted to re iterate, yes even if it looks clean, just a little bit can kill you. Silver can oxidie and corrode, some contact cleaner might help in that case. if it's tin flashed, then CC will work well there too. use a dip or q tip don't want to spray CC on the plastic, it might eat it.
Speaking of the plastic. the plug heads, especially when it's cold out, the stuff gets stiff, and very.... frictiony, it don't want to slide very well, and even that last 32nd of an inch / sub mm of travel to fully flush seat that plug flush, if it's not all the way down, that check fails, you don't charge.
i have found that some plastic cleaner / lubricant, like Car Wax, ie Turtle Wax or similar, carefully applied, (don't want to get it into the contacts we just cleaned now do we? ) can help make the plastic a bit smoother more slippery to help it slide in and out a bit easier.
Once i got the stuff cleaned the rest of the weekend went pretty flawless.
I wonder how hard it would be for Energica, or anyone really to make some sort of monitor that checks the comms / resistance across the connection, so you can get like an indicator on the dash, plug not inserted fully, or something to let you know it's an issue before things time out. or better yet run the shit at a higher voltage, or make CCS 2.0 for the entire industry, that has a wireless there like the gas pumps have, there is a bluetooth like thingie in the head and it comms wirelessly so you don't need to worry about low voltage issues. I know this is not just an Energica issue and it's not going to go away on it's own.
