Following the PHEV Watchdog App (which supports the Outlander PHEV, Kia Niro PHEV, Kia Optima PHEV and Hyundai Ioniq PHEV) and after some requests I've decided to create a new Android (only) monitoring App for Kia and Hyundai EV models.

Watchdog is a complete monitoring App, it doest not only extract and display info provided by the car systems in real time but creates more stats and analysis and keeps track of everthing by storing historical data in it's internal database.
At this time I'm planning two versions of the App, a free on ad-based and a premium one where users will be able to sync data to the website and have further analysis there.

It's still in the making but support for the Ioniq EV, e-Niro and Kona EV is certain.

I've started a fb discussion group (where I will be posting the developments) here: Facebook Groups

Here a couple of screenshots of the App.

Live monitoring screens (or where you see the info while driving)



The App keeps track in a list of the battery condition (changes in SoH and SoC). And you'll get one card for every changes seen (screen on the left). From each card (one tap) you'll have access to the details of the recorded state (right screen).


There's a lot of info there:
  • Actual BMS SoC [display SoC] = actual charge
  • Actual BMS SoH of useable capacity [factory capacity]
  • Actual useable capacity [factory capacity]
  • Total current (energy) charged
  • Total current (energy) discharged
  • Total usage (current charged and discharged)
  • Total battery operating time
  • Total estimated cycles as per factory capacity
  • Total Ah lost per cycle
  • Total Ah lost per day
  • Battery voltage
  • Battery current
  • ]Max available power in / power out
  • Minimum cell # id @ voltage
  • Maximum cell # id @ voltage
  • Average [target] cell voltage
  • Maximum cell voltage difference
  • Minimum : maximum deterioration cell # id (SoH)
  • Isolation resistante
  • Minimum : inlet : maximum battery temperature
  • Auxiliary battery voltage
  • Inverter capacitor power supply voltage
  • Fan output power
[/list]


Beside storing the battery condition the App will also keep track of every trip you have monitored with it.
Each trip is kept on a card list (on the left) and by tapping the card you can have access to the details of each trip (right screen).


Details inside each trip card:
  • Date/Time it was recorded
  • Trip duration
  • Trip distance (odometer at the end)
  • Accumulated ascent / descent and elevation (from device's GPS)
  • Data resolution / error rate (from the OBD2 interface)
  • % of glide time (moving without motor or regenerative braking)
  • % of regenerative braking time
  • % of stopped time (without moving)
  • Eco score (efficiency score calculated by the App)
  • Weather season (inferred from GPS and calendar)
  • Charge at the beginning / end of the trip
  • Maximum observed power input / output
  • Minimum / maximum observed battery voltage
  • Minimum / maximum observed cell voltage
  • Maximum observed cell voltage difference
  • Average [target] cell voltage
  • Maximum cell voltage difference
  • Minimum / average / maximum observed battery inlet temperature
  • Minimum / average / maximum observed battery temperature
  • Maximum observed battery fan power
  • Charge difference at beginning (difference from previous trip)
  • Average consumption
  • Wall-to-wheel average consumption (without regenerative braking)
  • Total consumed charge
  • Average / maximum regenerative braking power
  • Maximum observed motor torque

Stay tuned!

I would not recommend to mix Ah and kWh in the display as it is confusing. Better to just use kWh as it is most used these days.

Will there ever be an iOS version or do I have to dig out that old Amazon Fire tablet from the back of the drawer?

Cool, looking forward to it. Regarding:
  • Actual BMS SoC [display SoC] = actual charge
I would suggest that displayed SoC is the relevant information and that SoC(bms) is for academic interest only.

I would rather keep the two. Not sure yet how both relate, BMS SoC might be more accurate although Display SoC maps to the useable SoC.

Happy to announce the EV Watchdog Free App (Android only) has just been published.

You can get the App from playstore here:

And be sure to check the FAQ on the website:

Also if you're in facebook please join the Facebook group for the App:

Enjoy!

Sorry no iOS version... Doing in the development in my spare time and not having much
Shame, I’d pay £10-15 for an app like this on iOS (as I did for LeafSpy) but I’m not going to buy and set up an android device for it.

Excellent, well done. I assume as it supports the Niro it would work on the new Soul as well?

Hello Mark. I'm still looking to add support for the previous Soul models (working to get the odometer reading which is not directly available).

But in fact it might already be OK for the new model as it should use the new ECUs.
Did not have access to a 2020 Soul EV so maybe we could try that with yours, could you contact me through email please?

Thanks.
