I was getting some rather alarming range in my daily commute to work, so I put the range to test. It performed as well as expected except for one tiny thing.
There is most likely a way to re-calibrate the charge-meter to get a more accurate reading. Next time you do a test, it might be handy to bring along a generator. ;-)
Honestly that's not bad for a four year old battery considering you were in sport mode, running AC which is a huge draw on a battery and you weren't trying to hypermile. It could have gotten the 100 miles without AC I bet.... Not bad really especially for what you paid for it....the original owners? Well, too bad for them. .lol@the battery reading btw

The volt meter (the gauge on the right) is accurate but not especially linear, if you want to be precise you need to measure watt hours and know how many your pack's been charged to, in a word you need a Cycle Analyst.

85 miles with AC on doing "normal" driving is actually pretty good -I'd have guessed 40-60 miles myself. And hey, I don't know any petrol cars that let you drive the extra few feet home after they've run out!
But at least with a gas powered car you can put in a gallon of gas and get to a gas station, you can't exactly put a gallon of electricity into an electric car.
Jeff DeWitt as he was hoping for the last few feet at the bottom of the hill, I was thinking about a tow truck or a trailer, but then I noticed all those houses he was parked in front of, each with electricity.

It's called coasting. I ran out of gas in my truck once, which was entirely my fault. I *had* enough to get home, but ran into a traffic nightmare a mile long, which idled all of that away. I made a B line straight for the closest gas station, ran out of gas about a hundred feet before I got there, my engine cut out and I managed to have enough momentum after shifting into neutral to coast into the gas station up to the nearest pump.

eBike rider here, the amperage meter is always the better "battery meter" in my opinion. I drive a 2500w bike and once it reaches 1500w it's time for me to hurry home bc it'll drop to 200w in about 15km lol

My car in high school had a gas gauge about as accurate as that. It would go down normally for the first third or so of a tank, hang at about two-thirds full for a suspiciously long time, and then suddenly go "Oh, actually you're into the reserve now." It never quite stranded me, but it was not to be trusted.
85-mile range is really good, especially with an air conditioner turned on. Sounds much better when you say 136 kM. I would be carrying a small (charged) Battery Pack inside the car, that charges from the Regen Braking, but cannot use the stored power without flicking a 'Reserve' Switch on the Dash.
A battery meter about as accurate as the one on my laptop. Part of me wonders if something overheated somewhere in the electrical system after all of that """high-speed""" driving, since it actually got you home after you let it sit for a while.
You'd probably eliminate most of the weight savings with those heavy batteries, even with the plastic body. Maybe if he could get some conventional lithium ions, like that one kind everyone uses for EV conversions. Could be worth it, though, if he could also transplant the regen brakes somehow; that's something off-the-shelf EV conversion kits don't have.
The Trabant had a top speed of about 70 mph and no creature comforts like an AC. I don't know if US stations sell pre-mixed 2 stroke fuel - otherwise you'd have to concoct that stuff yourself from regular fuel and oil. Which is a procedure as godawful as the car itself.
About 15 years ago I borrowed my Father-in-law's Aerostar van to move my wife and me into our first apartment. It went well, we had 1/3 tank when the car just died in the middle of no where. We called him up, since he was going to meet us anyways, he brings a jerry can, and then says, "oh yeah, I forgot to tell you, fuel gauge is broken and 1/4 means empty". Sounds like my father in law programmed the wheego fuel gauge :|

As a Smart Electric driver - 87ish freeway miles is actually impressive. My 2018 Smart ED couldn't do that, using about 15kW draw to maintain 60mph - I'd be lucky to get 60 miles. Since the Weego battery pack is 30kWh, is it almost double the 17.6kWh capacity I have in my car - not bad for the 2013! Smart cars are built for cities - not road trips :)
Some electric cars have low propulsion shutdownsand if you have one cell that dips below a certain current the propulsion unit will go into limp mode and eventually stopeven though the rest of your battery may still be fine it could be a single cell that is faulty
Seems to me that with a double battery pack, the weego might actually drive at the promoted 35-75 miles range. But with the current pack, once voltage drops below a certain amount, it just doesn't have enough juice to push the vehicle.
Hey I was born in st. Louis! We lived in st. Charles. Is the city still a seperate entity from the county? Most don't know that the city isnt apart of the actual county. Or it didn't used to be.
Really not bad at all. Highway uses a hell of lot less power then city driving.. constant 30hp or so to hold highway speed. That figure can go from 30hp to over 200+ depending on what your doing (and driving) in town just to keep up
The odometer signal in a gas car is a pulse generated from the transmission and fed to the ECM.. In an electric car, pulses are counted from a circuit called a pulse width modulator, and in turn is compiled and displayed.
*do you not have a guage for temperature? could your lack of range maybe result from no or poor cooling like the first Nissan Leaf? might be something to look into*
It may have more range than a Chinese knockoff smart - but in every other single discipline the Trabant is worse than any other object known to mankind (even, though only by a whisker, than a Renault 4).
What about the Ford Pinto? Ford decided that it was cheaper for them to pay life insurance for people who died in car fires than to put a shield on the gas tank to prevent fires.
According to the specs on the Wikipedia page, the battery in this is 36s LiFePO4, 85v divided by 36 is 2.2v which is REALLY low for this battery chemistry, the usual low voltage cutoff is 2.6v!
My white lab coat seems to have gotten up and walked off on me, but I frequently run my ebike down to 3v / cell. 3 - 3.3v / cell is pretty typical for most lithium chemistries but LiFePO4 runs quite a bit lower. Regardless of chemistry there is no black and white threshold where degradation begins. Anytime you use your battery there will be some degradation, but not running it down to your low voltage cutoff (LVC) will go a long way to reduce it.
It kinda makes sense why the battery indicator is inaccurate. There’s circuitry that keeps track of charge cycles, and a cycle is when the battery goes from 100% to 0% and then back to 100%. But when you go from 100% to 80% and back to 100% every time, it can cause the battery to recalibrate itself to show 0% as 80%. It’s the exact same thing that happens with phones. People charge them from 30% to 100% every night, and the battery starts to think that 0% is actually 30% and it’s why they die with charge left. It’s why you should fully charge and then discharge your phone every now and again, it can recalibrate the phone to actually know what 100% and 0% are. *Too bad you can’t fully discharge this car*
I have an E Bike for years I suspect it is something to do with mass of amp and relative potential range. IE As my power is depleted IE further I ride less power there is for torque, And I wonder if that is why the gauge is meaningless or indeed technology allows more even draw on battery. But I am no technician, But love my E Bike.
Power required will increase at higher, but the amount of time that power is used will decrease. Traveling at 30MPH uses less energy than traveling at 60mph, but you'll be using energy for twice the amount of time in the same distance which will somewhat close the gap for the total energy consumption between the two different speeds. Correct me if I'm wrong. What I said may make no sense.
it is wrong with electric cars because they have a single speed 'gearbox', in an ice car that may be true because of the reduction gear. But you would travel way further at 30mph than you would at 60.
@Aging Wheels - It's wrong. As with all electric cars if you will go a lot further if you slow down. Btw I think 85 miles on highway is a good range for this little car.
Aging Wheels what you're saying is correct, however due to the fact that the relationship between required power and speed is indeed cubic, the time factor here won't matter nearly as much as you'd think

Range is highly dependent on speed. As speed increases power needed increases by a CUBIC factor.
Power required will increase at higher, but the amount of time that power is used will decrease. Traveling at 30MPH uses less energy than traveling at 60mph, but you'll be using energy for twice the amount of time in the same distance which will somewhat close the gap for the total energy consumption between the two different speeds.
