[New Car] Fiat 500e 42kWh (from 2020 on)

[Dopo]

More detailed car info here: EV-database.nl

Driving Model:

Option 1 - Analytical - Provide the mathematical parameters to define the car model (See this blog post for details).

--> Not possible as I do not posses the required parameter data.

Option 2 - Data-Driven - Perform driving test at multiple speeds, and record efficiency or power draw from the pack.

--> Not possible as the car's indication is limited to just an average consumption, nothing real time.

Option 3 - Direct Car Connection - Provide method of receiving telemetry directly from the car via OBD, API, or other means.

--> I ordered a Bluetooth OBD dongle to use with EVNotify and will do the measurements as soon as it arrives.

Charging Model:

Charge Curve - Provide a link to a chart or video detailing the charge power over time or by State of Charge %

--> I made a manual real-time measurement between SoC 9% and 87% at a Porsche DC charger in Brussels. I received an error message at 25% and 87% SoC. I retried and continued at 26% but did not continue at 87% as the ambient temperature was only 10 °C or even lower already. The graph images below are as well included in the MS Excel file for better readability. The 3th graph shows how long you have to wait for +1% SoC increase. It's quite clear that the DC-fun is out at 85% SoC

Before charging, the car was driven for about 150 km on the motorway to lower the SoC from 72% to a value as low as possible. At 11% SoC the indicator became orange and the car asks to find a charging station. Also another message is shown after, indicating that the battery will be heated up to prepare charging, but I am unaware of the existence of a battery pre-heating system on the Fiat 500e.

Hi @Dopo,

Thank you! We have already added this model but I'll add the excel file to our car data collection so that if needed, we can compare and see if anything needs tweaking.

From what we know the EVNotify is not supported for the Fiat 500e, or are we mistaken? If it works well we'd be happy to add it as an option

Hi Katya,

Yes, I noticed that this Fiat is already available in alpha mode, but maybe my data could be of any usage as well. Serve it as you wish.

Concerning EVNotify my goal is to link in real-time ABRP with the car via EVNotify, but that will not be possible then? Is there another app that can do the same? Maybe Torque?

I noticed that OVMS has already an empty page on its docs-website but it is still empty. So should I install an OVMS box to connect real-time data with ABRP? What is actually the relation between OVMS and ABRP?

Regards,

Dominiek

Tronity now Supports the 500e, but there is no option in ABRP yet to add Tronity to my Car

Yes, I contacted them and via the app of my car they could retrieve parameters to support the Fiat 500e trips and charging sessions in Tronity.

However, to my understanding real time data is not (yet?) available, as they only (can) capture the data when you start and stop driving/ charging, not on the go.

Hi @Katya-ABRP,

I noticed that I can connect Tronity with ABRP, but when trying to couple both, after logging in to Tronity, I received an unspecified error. Can you tell me what I have to do? Is it a Tronity or ABRP problem?

Hi @Dopo,

Not really clear what this error message means. I checked your account and the saved vehicle currently doesn't have an option for live data selected. When you attempted to link it did you do it this way?:

1. Go into settings (detailed) > Car model
2. Click the cogwheel to the right of your saved car
3. In the vehicle settings menu, (scroll down if necessary) choose a linking option
4. Do the setup as advised

Hi @Katya-ABRP,

I did exactly what you described (linking my Fiat 500e to Tronity.io). The error message occurred after successful login in to Tronity.io and clicking on ‘Allow’.

[Katya-ABRP]

Hi @Dopo,

Okay! Have you checked if you get the same error if you attempt to link through the web version of ABRP?

/Katya

[Dopo]

Hi @Katya-ABRP,

yes, my first message about it came from the website, the second came from my phone, but also in that case the connection attempt with tronity.io is made outside the ABRP app and in Chrome. I’ll contact them as well.

Hi @Dopo,

Alright! This does seem to be more of an issue on Tronitys side and I would as you mention suggest to contact them. If there's anything we can/should do, do let us know!

Hello, I have been using Abrp and Trinity quite successfullly with my previous EV, but I don't seem to have any success with my new 500e. All is connected and it seems to be down to Trinity just reporting trips (and not even in a proper way, I get them more than a day after they have been completed). Is there any way to read the battery level real time via obd yet. I have an obd adapter i can use and possibly have a proper reading to use with ABRP, but doesn't seem to be an option yet?

Thanks

Hello, 

I purchased a set from Power Cruise Control (https://www.powercruisecontrol.com/) and it reads directly the OBDII interface to an app on my iPhone (not ABRP). Tronity seems to be using another (unsuccessful) method (API?) to get information from the Fiat 500e.

The name 'Power Cruise Control' is a bit misleading but it gives you a live indication about your driving style in relation with the distance to be driven via a green-red display called 'Heaven-Hell' display: if you are getting in the 'red' zone, you will not make it with the current battery charge in relation to the distance to be driven. If in 'green', all is OK.

Now I have sometimes difficulties to establish a connection between the app and the dongle, so I needed to do a few complete re-installations of the app before it worked again. But when it works, it works :-)

I will take a look at the app, i would really like to use ABRP actually.. In THEORY the Uconnect Tom Tom should be smart enough to route me through the appropriate chargers, but it is very limited in respect to planning and seeing the chargers status compared to ABRP.

IMO nothing stands in the way of ABRP to reach out to PCC for cooperation concerning the Fiat 500e, just like they integrate with Tronity.

Although this is helpful, it really looks like something the Uconnect Tom Tom is already doing for me: i can indeed put a charger (or multiple ones) in the Tom Tom route and it will tell me if based on the battery level/traffic/etc i will be able to get there. It doesn't show me the red/green advice, but that is a bit out of my scope (i prefer to plan with enough margin rather then changing my driving style, and luckily where i drive there are enough chargers en route, so i mostly want to know if my next planned charger is too busy so i may decide to stop to an earlier one, which Tom Tom does not, or at least i have not been able to make it show)
Ideally i would put my destination in ABRP, with some appropriate filters in place, ABRP should drive me to destination while showing me the next charger status/availability and reroute if something is broken or too busy (i didn't try while driving, but it does if i reroute after each stop, and i can see next charger status while driving).
it DOES work, it just of course cannot track the amount of battery (but of course i keep an eye on it and is remarkably close, it's always been within 2/3% difference max).

I have found a little trick to sync the battery, after the last updated from Tronity, and now it pretty much works and is able to pass to ABRP the correct battery values: if I am starting with a full battery (or after a recharge) I can force Tronity to update the correct battery value by activating the climate request with the car still connected. This way when the routing will restart after the charger is disconnected battery value will be correct (i.e. the current one when charge has finished) not the one of when the battery has started to charge.

Tried during four days of long range trips with multiple charges it all worked with no more than a 2% difference between real battery value and the one reported by ABRP.

Hi @ricky1750,

I understand from your post that a manual action ("activating the climate request with the car still connected") results in a transfer of the battery state data from the Fiat 500e to ABRP through Tronity. You do this action from the Fiat 500e app, right? That part is not clear for me.

Also if I understand you correctly, this is only a 1 time transfer of data. So instead why not just manually type in the battery charge in ABRP after finishing charging and before driving away? Then you don't need Tronity at all.

In contrast, PCC does monitor the battery state every 3 seconds, so e.g. if it suddenly starts to rain and the car's consumption raises, it will detect this and adapt the estimations accordingly. I must admit that the PCC app looks a bit simple but it is smart because it reads directly the data from the Fiat 500e instead off using the Fiat API's, so was it explained to me. I just hope it will be integrated in Apple Carplay so that I don't have to keep my phone open all of the time.
