Dude, you did a stellar job explaining this. And I'm ordering this OBD test unit on Amazon now. But SOH is in fact the average of SOH-Resistance and SOH-Capacity via current. Thanks for this video, this helps a lot. 🤙🏼
You can read all kinds of data. As I recall the modules (grouping of cells) were readable. You can read the charge voltage while it's charging, which really would be nice to know as not all public chargers are consistent as 6.6 kWh. That should be standard on the IP. I'll do another video on other secondary uses later.
SOH-C is charge state of health, so how much energy battery can keep (spec capacity to actual capacity). SOH-R is power state of health, so how much amps battery can output.
PSA: Not all blue tooth OBD Readers work on our 500e's. Some of them when plugged in can cause the car to throw codes and illuminate warning lights. I had that happen with my blue tooth reader. (if that happens you may need to go to the dealer to get the lights and codes sorted out, or if you are lucky they will go away if you disconnect the 12v battery) Do as much research on the reader that you can before just plugging in an Ebay bluetooh reader you found on the side of the road. it looks like this guys reader is one of the good ones. but please be careful.
hello I want to change the original radio of my 500e I'm in Costa Rica and I can't use the maps, I want to use an android radio but I don't want to lose the special functions of the car like turning the daytime running lights on and off and the exit assist, and the opening doors with this OBD scanner I can access these
I wonder if this would also work on the new 2021 model. They still don't offer the option to charge to a certain percentage, 90% for example :( Only of they limit the battery pack from software, for example you see 100% charged in dashboard, but the real capacity is around 90% This is what i'm trying to find out, but fiat is not saying anything about it, so i have to test on my own. Alfaobd doesnt show support for the new 500e, only up to 2019. The software is free but i need to buy an obd2 and manage to get a laptop/android OS to check. I'm using apple devices.
Доброго дня. Я просканировал вчера свой Фиат с помощью ELM 327BT. ELM 327BT полностью показал мне состояние HV батареи, как на видео The Evolving World. Огромное спасибо!!! И я смог удалить ошибки на других устройствах автомобиля. Но в некоторые устройства автомобиля ELM 327BT не разрешает войти - требуется переходник или соединения клемм (радио, климат-контроль). Больше вопросов появилось по SOH, SOH-R, SOH-C. Если у меня SOH-C -83.53% и SOH-R - 96.47%, тогда почему SOH - 100%?
Thank You, I am happy you found the video useful. To answer your questions: Yes there are adapters that can be used with the AlfaOBD software to allow further access & reset functions. I would go to the AlfaOBD website and follow the instructions there. It is unclear to me if it's important to note the different percentages for each : SOH, SOH-R, & SOH-C. As long as the numbers stay high. My numbers went up with the last scan I did (1,000 miles later). I will continue to monitor it. As long as you keep it charged between 10-90% or even better yet, closer to 50% (for longer periods of inactivity). You would be doing the best you can to make the battery last as long as possible.
@@theevolvingworld Спасибо Вам за ответ и советы. Вы правильно заметили, что машина много простаивает без движения. Это связано с погодой в Украине и дорожным покрытием после снегопадов. Я в хороших условиях погоды буду эксплуатировать машину и посмотрю на изменение SOH (-R, -C). О результатах сообщу.
Great series. Much appreciated Sir! Mine readings: 2017 MY 17,700 miles SOH=100% SOH-R=99.22% SOH-C=91.37% I am wondering whether FIAT may have secretly upgraded the battery as I am routinely getting >100miles range, even with AC on in 90F weather with mixed highway/city driving. When fully-charged the gage shows between 106-116 mi range and I have seen it as high as 127 miles.
Do you know if there is a tool for reseting faults. I am having a problem with my battery and it keeps trowing a fault of a parasitic loss and shuts the car down
Go to the AlfaOBD web site. It says if you use a OBDlink MX adapter that it adds the ability to clear faults thru the same software. It costs about $80 on amazon. I might buy this myself for my EV conversion project powertrain. Currently, I've never had any faults. I'm not sure which "battery" you are referring to. But, remember there is a 12v & a HV (360v). I've said this many times before: The 12v battery is the weakest link in the whole system. When it get's old & near end of life, it will kill the whole system. Solution is: simply replace the 12v when it needs it. About every 3-4 years OR upgrade to a LiFEpo4 Lithium 12v battery and never worry about it again. See modified #18. Cheers.
Not that I know of. It would be nice to be able to set a specific % to stop at. Only Tesla's from Model S on, allow you to program whatever you want it to stop at. The Roadster & the other Tesla joint cars (RAV 4 EV & B250e) default to 80%. Also, LEAF did 80% on just the first few years. I think Volt did too. There might be some others.
If I'm not mistaken, these limits are built in. There is a usable battery range to preserve SOH and avoid SOC degradation. (roughly 20% - 80%) So, 100% charge indication is actually only 80% of what that battery cell can actually handle. Now while it can handle more, that does not mean it can do so without degrading the battery. Same goes for discharging.
I control that by a decision how long to charge. I control that from my iPhone, using (Internet) remote power switch (Smart Plug Mini Outlet AISIRER Wifi Socket ). It is extremely simple.
@@mattdavis9223: If what you've seen is true, then it would seem the data history in this videos scan would show much lower history of times charging at 100% and 90% than it does. But logically, the lengths Fiat goes to to manage the battery's temp and so on, that they would, as you say, only charge to 80% true and 100% indicated. Does anyone know of a Fiat or any source to verify this?
:@@georgekren6185How do you know when it will be charged to 80%? Do you use %/hour, and calculate it out every night? or do you drive pretty much the same distance every day and just ball park the cutoff time the same time every night? (my 500e charges about 7%-8% per hour@120v)
I know this is a few years old, but thought I'd ask in case you're still reading comments here. I noticed in your system status log it reads 72k miles on the odometer, but when you show your dash it's around 48k. I point this out because when I ran AlfaOBD on my Fiat 500e the same inconsistency showed up. My dash reads 19800, but Alpha reads 31529. At first I was very paranoid a previous owner messed with the reading (even though the battery levels are quite good), but saw this happened in your video as well. Any idea what that's about?
You can do a 100% maybe once a year as a top balancing reset. But, for longevity keep it between 20-80% as much as possible. For long term storage 50%.
Hello, thank you so much for the video. I have a ODB 2 reader (a good one. ScanTool OBDLink MX) I read in some forums that connect a obd 2 adapter could brick or damage the car? since they said that is not obd 2 port? Do I have any danger in trying?
The software I used in the video is from the Manufacturer of the car... and it's free! It doesn't get any better than that! Why take chances gambling, when you know how to win?
Hey thanks for the reply. Yes I'm going to use this software, I was not talking about the software but the odb reader itself. If connecting the reader would damage the car (even using this app)
I thought you were talking about a generic OBD-II scanner that display codes right on the device. If it's just a access device such as the one I used, then I would think it's worth trying. It's just a portal to access data. If it crashes the system, the reboot is simple... unplug the negetive terminel on the 12v & reconnect it. Cheers,
@@alstonhsu3804 yes. I was asking since I found that post. And that happened to me. But my Fiat start doing all those symptoms when I disconnected the battery. In that time I took it to the service (under warranty) it I was looking for a way to reset if this happen again. Anyone knows for an official cable for the 500e?
I can't imagine that would be allowed or legal. But, than again, it's all just electronic digits. Not a mechanical odometer, where it's obvious if it's been tampered with. You can check the battery history to see if it's newer.
I don't know all the differences. I just know this one works! Others may work too. As long as it's ELM327 it should work, but you won't get your money back if I'm wrong.
Nope. The dealer I bought the car from fixed all recalls before selling. Last recall was 5/16/16. Your a little late. All 500e's built feb 2016 & later are recall free!
Javier Victor Mariano Bruno yeah I had mine taken care of 2 weeks ago. Something about the battery pack trying to charge the 12 volt battery when the car is off and it drains the battery. It did happen to mine. I would charge the car overnight and in the morning it was saying 99%
@@AlexanderKotlyarov When battery is new, it's 63 Ah. Your at about 75% capacity. I did another newer video on battery degradation showing the importance of the other numbers. I bet you get about 5.4 - 5.7 miles a Kwh on average.
Same here.. SOH 9.804. I drove the car empty a few weeks ago. Real empty till it went to the 12V battery. This because the calibration wasn't good. And I charged 18KWh after that.
