Finally, Back to Lead acid and a FOUR WIRE EV! (Something I can maintain)! (4 wires, means 2 from the battery, and 2 to the motor and a controller in the middle. Done)...
I have given up on modern EV's (two THINKs) who are BRICKS because the computer in them thinks something is wrong and they want to "call home" but there is no "home to call" (they are out of business). And I HATE trying to hack an unknown embedded CPU... I prefer turning wrenches and pots.... Anyway, I pulled my old converted Honda Civic (ten Lead Acid) out of the weeds last night and of course, having been sitting for at least two years, the batteries were dead and would not take a charge form the installed charger. SO I moved through each one with a small parallel 12v battery and a normal 12v charger. The battery helped convince the portable 12v charger that there was a working battery until the charge got started, then I could move on to the next battery. Now they are all hissing and bubbling away. And after maybe 12 hours (on and off, since I only charge while I am nearby and can monitor them), anyway now, the charge is finally beginning to taper from the original 9.2A down to about 7A. Then I had to come to work. Maybe this evening they will reach full charge and the charge will further taper. All the cells had water over the plates, some higher than others, so I now have them all topped off. I know that long-term sulfation is a problem. But these batteries were close to charged when they were abandoned more than a year ago. So they did not start their long abandonment discharged, but did so over time. So any opinions on recovery?
