The SOH-C stands for the capacity retention (current capacity/65.09Ah original capacity). The SOH-R may be the SOH in reference to resistance growth. Both numbers are important and should be referenced.
Great videos! Love your content.
Super useful dude thank you
Thanks!
The Evolving World my buddy and myself want to buy a 500e I was wondering did you have any luck with finding a battery that improved your range?
Some things that help with range are: light weighting the car, driving gently, no hills, no headwind, keep the speed down & don't drive in cold weather. There are other things like LED lights & skinnier tires. But, Battery Degradation will happen, sooner or later. At some point, a battery swap could be done.
The Evolving World hell yeah man, thanks super good tips, thank you. Do you have an Instagram aswell?
The other day I bought a used 500e and watched your youtube on how to read the battery SOH. Here are my readings.
HV Bat SOH: 39.22 %
HV Bat SOH-R: 76.86 %
HV Bat SOH-C: 80.39 %
Your video seemed to say SOH is the average of the -R and -C. But in my case it's not.
My car has 38.5 k miles and it seems to be running as normal. Do you have an email address?
Most EV batteries degredation is not linear, it slows, so maybe not as bad. Samsung battery thermal managed, should be typical. I hope for 200k useable if i can partial charge at or near work.
I've been trying not to top off when I don't need to.
I top off but only when I know I'm driving it in short order. If the car sits I try to have it sit between 40 and 80%
Your probably right. I heard that about Tesla's in particular. Dropping to 95% quickly & then flattening out nicely (also helps to have a battery x4 the size). The user is the biggest factor. If I bought my 500e new, it would in much better shape. But, all in all, for the price paid & moving at the rate it is, i'm very satisfied.
@@theevolvingworld I agree, people fearing the battery helps keep prices low & makes it 1 of the best deals!
Nice job, very helpful information 👍
The Fiat 500e is a great little city car. Great for students and grocery getting.
Could use a bit more range though.
... or a grown man's primary car, to & from work, etc
Do you know or heard if the BMW I3 SDI94Ah batteries would work as a replacement for the 500e batteries?
I own a 500e. The car comes with an automatic 8 year battery warranty. So all these numbers really mean nothing to most people. Older generation Nissan Leafs are still on the road with their original battery packs. They were only supposed to last 10 years, but they are still going. I have an electrical engineering teacher at school who is always trying to find fault with EV's. His logic is, well try driving one across the country. I'm 53, I've never had to drive across the friggin country, that's what airplanes are for stupid! 95% of the people don't usually go more than 50 miles during a normal day.
When you are retired like me you can drive 60 miles 1 way with a few stops for charging. Then another 60 miles to home. That’s Fontana to Los Angeles international airport to pick up a buddy from the Philippines
if you dont drive but about 30 miles every 3 weeks or so , how would that affect life of battery. keep it charged up to 90% alway? retired dont drive hardly at all. just want the covenience of not going to gas stations and smog stations.
Keep it at 50% when doing long-term storage for maximum longevity. So, unplug it at 65%, drive it, plug in when it hits about 30-35%. At that pace the car with last at least a whole human lifetime!
@@theevolvingworld thankyou
Battery performance varies depending on your driving habits.
and top speeed and high acceleration reduces the SoH very fast
How much cost the replacement new battery for 500e?
too much
@@Milkshakman for a new AC compressor 7k. Imagine the battery. Ended up getting a junked fiats 500e AC compressor for 350 USD. Install was 900 at fiat dealership.
Oh I just realized I got the compressor from the owner of this channel. Really nice guy to work with. Compressor has been working great now for 3 years
Exactly what I needed to know. I am thinking of buying one with 59,000 mi on it at around 13,000usd. Could be worth it?
Nope not worth it. I bought mine for 4600 USD with 43k miles on it. Back in 2017
I didn't lose range until about 80k miles. They go as low as $7k now. Trying to sell mine soon. Fun car, fast off the line.
The temperature will affect all of this. You ran scans at 47 degrees. Try at a higher temp and your numbers will improve. Your battery degradation rate should improve also.
please use celsius. nobody outside the US knows fahrenheit ahat is 42F?
Have you ever measured pack voltage to see the voltage at 80% and 100% SOC? If so what is the voltage per cell at each SOC?
So in 10,000 miles the battery capacity or range dropped 3%?
Can we get a better battery?
If we can keep these on the road long enuff
It is not normal for it to degrade so quickly!
My SOH 100%, SOH-R 99% and SOH-C 80% (+ -1%) did not change significantly in 1 year and 15k KM (now 78k KM).
Your at about the same capacity as mine was at 78km (48,500 miles) "Ah" is the number that really matters. "SOH-C" is more of a rough estimate.
@@theevolvingworld I really enjoy your videos, very accurate information Thank you so much for sharing with the EV world.
I bought my 2015 FIAT 500e with around 37k miles, now it has 55.6k miles on it. It's been a magnificent little car, I owned a 500 gas powered once and I wouldn't change my 500e for anything (I know, is not perfect but it gets the job done).
My full AmpH capacity right now is 47.5 Ah and I'm getting around 65 miles of real range. My battery degradation is showing to be more because my driving cycles + charge, since the last 2.5 years ~90% to ~15% five days a week traveling and average of 65 miles using level 2 charger.
I know probably next year I'm going to replace the battery module to be able to keep my driving habits.
I wanted to share it with you, I thought it might give you more insight on how our batteries will degrade in the next couple of years.
Thanks again! Keep up with the amazing work.
@@TheArangoJuanPabloT Thanks so much for the kind words. It's nice to get a little bit of appreciation for the work we put in. Also, thanks for sharing with the community on your personal experiences.
how are you able to charge to 90%? I haven't been able to figure out how, it always charges to 100% unless I manually unplug it at 90
Bingo
Yes, manually unplug. Tesla's are the EV's I know of that allow the user to set any limit you want. 🤔
My 2019 Kia Niro EV has an easily adjustable adjustment on screen in car, or by app, to adjust charge limits in 10% increments. I usually leave it set at 80% unless planning a long drive the next day.
@@jonathanwolman1049 Thanks Jonathan, that's good to know. I should have said of the one's I've driven & reviewed. The Niro EV is definitely "on the list" for the future. Also, possibly the Jaguar I-pace might allow to set charge limits. I drove one for about 12 minutes or so at last year's auto show, didn't have time to check. Anyway, all proper EV's should have the ability to set charge limits & show a state of charge % while charging.
You can program by time, but it seems like a pain
I just bought a 2017 500e eSport edition in California with 19,000 miles for $11,000. 6/27/23. Shipping to Philly for $1,200.
I come at it from a different point of view. I have an Ebike and learned proper battery management from it and DYI battery packs.
Is there an internal heater to allow for charging below freezing?
I charge very slowly with my e-bike at 1 amp instead of the default 2 amp, but sometimes 3 amp. You should charge to 100% at least once a month because it allows the cells to top balance. Slower charging is more efficient, since it creates less heat showing wasted energy.
The reason to charge to 15% and 85% is due to the charging and poor performance. At below 15% performance greatly drops like off a cliff. Low voltage means poor acceleration. Stopping at 85% is wise because the battery gets a bulk charge rate below 85% and an absorbtion rate above it.
I expect to charge my car at 110 volts with my solar generator that holds one kilowatt. That should give me for miles extra distance. Ideally, I charge the solar generator with solar panels fixed to my roof, and charge the car in the morning when cool. I don't drive much currently, so 4 miles a day capacity is fine.
Welcome to the Fiat 500e world. It's a solid car with no touchscreens. 🙂
Yes, the HV battery is heated & cooled. Checkout my Fiat 500e "teardown" series if you really want to know all about your car. The "heater" is about the size of a loaf of bread & is located near the traction motor in the front. Ciao.
Goodmorning Sir, nice video.... I watched a Fiat500e end of 2015 , do you think that the battery is still in good condition at 22000 KM ? I don’t know the battery tecnology tthat they use for made it.... but i think all year it’s better.... Waiting to you for your answer . Thank you Claudio
Thanks. The only way to be sure is to scan the car with AlfaOBD.
Is there a charge setting to 90% ?
No, you can estimate & use charge timer
...i wish
90% is the goal. Reality is more like 80-95%, depending on the distance of trip & whenever my hand unplugs the cord. 😉
-Has anybody price the Battery replacement & instilling or the 500e??
At level 2 the main battery🔋 basically charges at a rate of 6.25% every 10mins
I understand that the SOH-C represents the capacity relative to original. Are you sure the original Ah is 63? If you divide remaining Ah on the given day by 65, this closely matches the SOH-C % relative to original. For example, for 21-Jan-2019 50.8 Ah / 65 Ah = 78.15 % , which is close to the listed 78.04 %. All subsequent calculations closely match the SOH-C % if 65 Ah is used as the original.
That's an interesting observation & makes sense. However, I continue to observe that "SOH-C" number stays flat sometimes, whereas the Ah always adjusted. Also, to consider, does the car's computer just display the actual full pack size or is there always an extra 1 or 2% always kept in reserve. Although, that would add even more mystery & confusion. 😕
do you know how much it costs avg to charge fiat 500e from 10% - 90% ...does it cost more to fast charge ?
When new, it has a 22.7 kWh capacity. 20% off of that would be 18.16 @ .10 a kWh (which is our local utility rate) would be about $1.82. Maybe a few pennies extra for transmission losses. Depending on your rate in Indiana & how much capacity your battery currently has, would determine the cost.
Probably cost about the same 110 vs 220 home charging
I’ve read it costs less to fast charge on home electricity. Some quirk in how power utilities calculate usage...
this is great but u maybe should take into account your DoD somehow since the depth of discharge has a huge impact on battery longevity
There are two problems with this calculation. You are ignoring the fact that (1) an electric car battery is considered to have reached the end of it's life when it's down to 70% of its original capacity, and (2) the loss in capacity can start to accelerate considerably after you're down to perhaps 75% capacity.
the truth is that this electrified fiat 500 was a terrible car which should never have been made.and haas nothing in common wih the new 500e (which i am happy to have) i recommend you the SoC betweeen 20 and 80%, some say even 30% as a minimum. and i recommend you to switch from your miles per kWh to kWh per mile because that gives you a better comparison to the capacity, which is measured in kwh., (by the way: when will you americans eventuallly change your measures toi the international km (and liters instead of gallons) like the rest of the world). andd your medieval fahrenheit instead of celsius. your numbers are of no use for me, or anyone on the other side of the atlantic ocean and you will never understand what my consumption of 11 kWh/100 km means, and whether 4°C is cold or warm...
Thanks for your thoughts. As far as the USA changing to the metric system for measurement units... hey I'm all for it. Back in 1975 , legislation was passed to slowly implement the metric system. However, it's been voluntary and Americans simply refuse to change. Some companies that trade to other countries do fully use the metric system, such as the military. We continue to be the only country in the world to use this measurement system. The UK uses miles for vehicles but everything else is metric. Maybe one day, we'll get fully in sync.
@@theevolvingworld by the way: do you (wanto o) know why most countries have driving on on the right side? it has historical rasons most people do not know.
