reverse its polarity! The plus terminal becomes minus, and the minus

The battery still (barely) works, but has very low capacity and short life.

It might be a bad solar controller.? When on shore power, long term, the converter output drifts up to 13.8V That is a safe charging voltage.?
Understand that the converter is regulated at 13.8 (at light or no load), but that's whats measured at the battery when the batteries are fully charged? to 12.8V? (after a half hour for the SURFACE CHARGE bleeds off)?
If the batteries were discharged down to 12.2 for example, the converter voltage will sag lower due to the higher current output.? After a 24 hr whole day on shore power, you should read 13.8 volts while still connected. But If you immediately unplug from shore power, you still will read above 12.8 until that surface charge bleeds off.
There are several ways to test the health of the battery.? Best is after a full charge, disconnect/isolate the battery from all sources.? Immediately log down the measured voltage.. then you will get a fakse reading above 13.0 you have to wait for the surface charge to bleed off.
Wait 24 hours or better 48 hours.? Check the voltage again.? If it still read 12.6 or more its i holding the charge.? I fit drops to 12.4, its worn but still serviceable. with reduced capacity.? If after 48 hours its 12.3 the battery should be replaced..

Re: Mechanic for 01 EV WK in Chicago?
Hi all.
I brought my van to Import Services in Glenview and met with Dan the owner. Both he and his partner Austin looked over the van. First, a bit of background:
I bought this van new in 2001 from Autobarn in Mt. Prospect. Every single service has been performed by their shop up to this point. (Oil, filter, tune, etc.) Yes, I was one of those people that thought that the only reliable place to take care of my van was the dealer. I had a great relationship with one of their service managers., and felt I was being treated honestly and fairly. A few things recently caused me to consider looking for an independent shop. The dealership changed hands a few times in the span of 2 years. My service guy was gone. I was also given some misleading info about a "new" Interstate battery that they installed, but in fact was a VW branded battery, that looked much smaller than the space it was in. Since the battery cover is always on, I never noticed this until recently. I also had the oil leak mentioned above and after leaving the van a few days, was told not to worry about it. They didn't find anything terrible. But it always bothered me.
Over to Import Service I go. After a few days, I got a call that the leak was coming from the head gasket. But it is not a leak, more like seepage they said. As soon as I heard head gasket, I immediately thought here goes thousands of dollars. In fact, to replace the head gasket, you apparently have to drop the transmission and engine to replace the $200US gasket. There was a possibility they could do it without all that, depending on a few factors. They said total cost would be ~$2000US to do that. That actually was not as bad as I thought it would be!
BUT, their recommendation was to not do all that. Again, they said the seepage was minimal and they have seen worse on other EV's. What they did recommend was driving the van MORE! My EV tends to only go out of the garage to go on camping trips locally. Our trusty Toyota Corolla is the daily driver.
My van has under 82000 miles on it. Most of that is highway miles. Or miles to drive to get the oil and filter! I still have 50% of my original brakes! Oil and filter is done by time, usually changed about every 6 months. I do baby this thing: zero to sixty in 90 seconds, coast to stoplights and signs, and leave about 20 car lengths between me and you. Yeah I am one of those guys!
So I think I am going to just leave things as they are, try and drive a bit more. Apparently, this may even help slow down said leak. This shop is fully capable of doing the head gasket and they could have just as easily said yeah, do it. And maybe if around a few thousand, I would have. When I asked what I owed for the diagnostic, they said I don't owe them anything! I was not going to take the van unless they take some of my dough, so i told them to spend some time going over the entire van since the only service to look at it for 20 years was Autobarn. They did that and reported back that I have been taking really good care of this thing. OK, how about changing the battery since it died once over last winter?Been fine since. Since the battery was pretty new, losing charge once was probably more forgiving than one might think. They said to put a new battery when this one sounds taxed or doesn't start the van. How about wheel alignment? They asked if van was pulling left/right, un-even tire wear? I said no. They said save your money. My total cost for all this, plus my talking and asking questions endlessly was a whopping $66.00US!
All that said, they will be handling all work for our 2017 Corrola from here on as well. Great guys. Most of their clients come from referrals and word of mouth. I am luck to have found Import Service. Here is to a happy marriage with them! I am hesitant to share this. I want them all to myself.

That¡¯s me (the someone) who has a flexible panel made by . It folds like a suitcase and has 120 W output. I like it so much. My house battery is Always topped off with that setup. I used to put it either over the hatch door at the rear when it¡¯s opened or on the top bunk in the front. I had a shop made me a long cable (gauge 12 I think) to replace the one that came with the kit and that was too short. I think it¡¯s a better idea than a solar panel fixed permanently on the roof of the camper. Two good reasons helped in my decision. First, if I had gone with the permanent setup, my EV wouldn¡¯t have fit into my carport at home because of the height and second, with that portable solar panel, I can put it everywhere on a campground so it can catch the sun rays !!! I use a microwave and a LED TV in my camper all day long.

Someone mentioned using the clamps on the cable that came with their solar suitcase.? Those typically have the charge controller mounted right on the panels.? This is convenient in some cases and certainly flexible for multiple situations, but ideally, you really want that charge controller as close to the battery as possible.?

There are significant voltage drops in the wiring. The alternator could
be outputting 13.4v while driving, but only 13.0v of that gets to the
battery.
Voltage is actually a rather poor indicator of state-of-charge for a
lead-acid battery. Voltage is affect not only by state-of-carge, but
also by current flow in/out of the battery, temperature, type and age of
the battery, and other factors. But with a sealed battery, that's about
all we've got.
A meter that measures amp-hours in/out is more accurate, but also more
expensive. The best one I've found is the Xantrex Link-10 family (which
used to be the Heart Interface Link-10, which used to be the Cruising
Equipment E-Meter). They measure not only battery voltage, but also
battery temperature, current, and count amphours in/out to provide a
better estimate of state-of-charge.

Hey Mike,
A question on the comment about the battery?being only at ~85% SOC following a day of driving.? The alternator output at $13.4V is equivalent to the float charge voltage provided by either the 120VAC charger or solar charger and the purpose of float cycle is to keep a constant voltage on the battery to maintain full charge w/o overcharging.? My thinking was/is that the battery?would maintain it level of charge while driving if fully charged.? Can you help me understand why the SOC would drop tp 85% when driving?? There are trips where I am 3or 4 days off grid and would like to start at full SOC.? Maybe a battery disconnect for the house battery makes sense if departing with fully charged house battery.
Thanks!

In some cases you may encounter difficulties, but they are generally not dangerous: the more common issue would be that you end up with a slight undercharge. ?
As an example, my SCC wants to charge the house battery to 14.6V.? But while driving, the house and starter batteries are connected by the relay so both are connected to the alternator.? The alternator runs at a lower voltage (closer to 13.8V). ? At the end of a long day driving, the house battery may be only ~85% charged.? Not perfect, but good enough.

Can a solar controller be left connected to the coach battery when the house AC charger is active?
My plan is to have a portable solar panel for occasional use when away from AC, which I would disconnect and store when it is not needed.

I think it can be done, but would appreciate your input
Thanks in advance
