Using a strong (like iCharger or similar) RC Modeller charger you can charge every cell wit the LiFePo Programm @ around 10 Amps. You will end up with a nicely balanced pack. Like your videos!
Try towing it around. The regen braking might help recharge the battery enough to work normally again. Batteries might not accept a charge from a charge if the batteries are dead but they will most likely recharge through regen braking.
Poor Wheego. I've had cars that were terrible, yet I still miss. My 4 speed 1985 Dodge Colt comes to mind immediately. I could write a half hour long script on just the problems I had with that car, and what fun each of them brought to my life. The only thing that worked right was the engine, and that was a Mitsubishi :)
No. AvE has his style, but he is by no means an "idiot". He knows damn well what he is doing and likes to get a chuckle out of getting people to freak out about him not doing it "the proper way". You could call it "minimum viable".
In 1987 I was in Yugoslavia for work. I took a taxi one morning, a Yugo (Zastava). It was falling apart. Second gear wasn't working and the engine seemed like it was running on just two cylinders. I found that the driver spoke some German and asked how old the car was, and was surprised to find it was only about four years old. He said that parts were extremely hard to get and expensive because all the really good Yugos were being exported to the U.S.
't Was my first thought as well.... Though I myself would only remember to do that at the exact moment I'd hand it over to the mail clerk. But maybe it would look mildly suspicious if the day after announcing the death of my Wheego it would rise back up out from the grave.
Would've been the sneaky thing to do, I know I probably would have done that. But isn't that only half of the equation? You would still need the diagnostic plug-in-device-thingy to actually communicate with the car, I doubt that there would just be a USB socket somewhere.
@@elogy890 I would assume it would use an off-the-shelf interface, either Ethernet or CAN, and a cable supporting either would be trivial to get. Where things might get fishy is if they put DRM in the dongle like VCDS (the homebrew diagnostic system for VW/Audi cars).
I’ve come to love the jankiness of the Wheego and want to see it live, but on the other hand, I’d really like to see the train wreck that is the undercarriage
Regarding the headache, is there a chance your whee-go battery is boiling and evaporating and you were experiencing mild lead/sulfur/litihum poisoning?
@@BadMax02_VR yea but that doesn't contain lithium. Also if it boils it boils of water and electrolyse the water boiling lead and sulfur dioxide is harder than you think
When I did custom software development (in Tulsa, hi!), we eventually made the observation that "there are no one hour tasks". If you budget two hours for all of your one hour tasks, you end up capturing many of the "zero" hour tasks you didn't think were going to take a measurable amount of time.
Well, I enjoy watching you mess about. As a mechanic, I agree you've fixed stuff reasonably well. Ah and I woouldn't quit my dayjob for a singing carreer.
I made that same modification to my lift. The electric box of my lift was big enough to accept the socket so now I have an extra welding plugin location.
You can likely resurrect Weego battery. Remove it and fix it. You need to play with multimeter. Measure voltages of those cells. Also get a charger from Ebay. Like. SkyRC B6. Original.
The BMS won't take a charge if the battery modules are below the cutoff voltage, so if you want to save the batteries, you're going to have to remove the cells and charge them individually. If you get lucky, you can use a constant current/constant voltage power supply to force a charge into them, which will raise the SOC high enough so that the normal chargers can take over. Otherwise, they're gone, especially if you leave them for too much longer.
Thought about making a window in the sloped roof section? Like on a Oldsmobile Vista Cruiser or a Buick Sport Wagon? Let more light inn from above and ad a little design element from the large wagons of the late sixties and seventies.
240v is what we have in the UK for all our household power outlets, we call them" plug sockets " that's why we have the 3 pin plug. We need this to power an electric kettle quickly to make tea, nothing more
If batteries are from the Lithium iron phosphate type, they can usually be revived even if down to zero volts. (The voltage being too low may be the reason why either the charger is not starting or the bms prevents the charger to start). Last time I had to do it, I slowly brought each of the 20s pack of my maxi scooter from 0 to 30v each with a lab power supply set up as constant current source (max voltage set to 30v) with a pair of amps or , starting from less than an amp at the beginning, before the voltage raised. Took some time, but they came back alive no problem, and at the end the voltage was high enough for the main charger to pickup. I'd suggest to try the same for every group of four.
Along with cleaning the metal prior to applying the primer, you also need to use an abrasive to scratch the surface. Even though it says self etching, it still needs the surface abrasions to adhere to.
As I wrote below the last video, I assume the batteries are still fine(ish), but the undervoltage protection has kicked in. Lithium Iron Phosphate batteries are pretty robust against deep discharges. You might be able to recover almost all of your capacity.
Nissan Leaf battery packs, custom a/m charge controller and control module to the factory motor. I think even if it takes some time to gather it all, it'd be cool to have a electric car that no one has heard about to cruise around in.... I'm sure Rich Rebuilds would have some info for doing this if needed.
Wheego's internal charger is faulty. Actally, different LEDs not lit on the batteries is a good sign, they are probably ok, but not getting charged properly. Different source(s) from the outlet energize different parts in the charger to get batts charged. First you need to check electrical contacts (conductivity) between internal charger and batteries, as you might be lucky to have a bad or oxidized connection. Then, there is charger itself, for which I suspect has something burned out. It does not have to be something complicated, and I suspect it is the circuit that connects those golf-cart chargers into joint batt charger.
My Wheego has perfectly fine electronics and motor. Sadly I live near Seattle and the Wheego leaks from every imaginable place. Since I don't have garage space available it fills eith water every time it rains. So I have it covered with a tarp, and there it sits.
No matter what, the Wheego can still serve a useful purpose. It makes the Trabant look good! To be honest, I'd never even heard of Wheego until I saw your videos about it.
You could charge every cell by itself with a LiFe-capable charger. RC models use LiPo and LiFe batteries, and that means chargers are cheap and available.
I operate on Latino Standard Time. When showing up at places LST is somewhere between 5 and 20 minutes behind normal time. And when it comes to projects and time management it doesn't sync up at all.
Hmm... if you don’t mind parking the wheego there, why don’t you have a 240V outlet there? You can wire a plug into the lift cabling that way it can be unplugged when you need to charge the wheego, and vice versa. I live in Australia and that’s how it’s done here. There’s almost always a 15A plug socket for the lift, which use a different socket (they use a larger earth pin, so you can plug 10A stuff into 15A or even 32A just fine, but you can’t plug that stuff into a normal socket), and that 15A socket can sometimes be the only 15A socket you have in the garage, so it’s really bloody handy if you need to plug in some piece of industrial gear, you can just yank the lift out and there’s your 15A.
From how it's acting, you might have flipped polarity on some cells. I would try to charge it one cell at a time, at least enough that each module powers up normally. Then it might change up from the port properly
Are you sure the car doesn't have a recovery mode? When you allow a lithium cell to go all the way to zero or even close to it, you will usually have to charge it with a very low voltage to get it started and then you can charge it with a regular charger.
If you want to keep the Wheego LiFePo4 battery and to wont charge with the onboard charger use an external charger to keep the battery packs alive, if they discharge to much you will damage the packs.
You're doing great. Keep it up. A useful rule I use for time and cost is to announce a "gut level" estimate of both then have my wife multiply those results by π. Why have my wife do it? Then she can be justified in saying "I was right, dear." Of such small things are happy marriages made.
well, if the 220 volts doesn't work for the wheego, may i suggest running cables off a high voltage power lines, around 35k volts 700 amps might work. just guessing here, trying to help :)
Gotta always remember the rule of pi! If something is supposed to take 1 hour, you can count on it taking 3.14 hours. Budget of $100? Nope! Bump that up to $314.
I think a solution to save the wheego would be to see if it is at all possible to find a replacement wheego lithium battery, or at least whatever one they bought off the shelf.
I would pull out the batteries and charge them via a model battery charger with balancer direclty and as soon as the batteries are all happy you cab reattach the BMS modules. 4s should be no problem to balance with a model charger. Take forever but that is how I rescue my batteries.
Had a bunch of bosses that would always say "that should only take about 20 minutes". You could swap in a twin cylinder from an old lawn tractor into the blue car.
Did the Wheego's batteries get below a minimum safe level? Lots of battery management systems won't charge a pack with cells that measure below a safe voltage, this could cause the entire pack to report as faulty when only a few of the cells may be damaged. I'd start by testing the voltage of each pack and determining what their nominal, maximum. and minimum voltages should be.
You were a software engineer, you know good and well that no "temporary fix" is actually temporary
The fact that the lift isn't able to be used, and how the thing is dangling from the lift, he's probably going to make that temporary
'Temporary' is such a wonderful timeframe since it could refer to the next ten minutes and the next ten years and still be valid.
"there is nothing more permanent than a temporary solution that works."
Now he's an actual engineer :)
