EVOBD2 is a Mini Bluetooth OBDII Display

For these electric cars

HYUNDAI: Kona EV – Ioniq 2020 EV

KIA: Niro EV – 2020 Soul EV

EVOBD2 is a tiny smart display Plug & Play, simple to use and always available to show hidden information from your main car displays. Mount it on the dash, leave it there if you want and use it automatically!

“You don’t have to be a geek to see what’s going on in your EV, but geeks love EVOBD2!”

EVOBD2 gets data from the car’s computer and displays it on 7 different available screens.

You can monitor battery state of charge, temperature, state-of-health (SOH), indoor temperature, auxiliary battery state, cumulative charged and discharged energy usage and more effortlessly at the press of a button. See all it can do and details down this page. We like simplicity, everything you need is on this page.

There is also an innovative energy counter that you can use during a short drive, a multiple day road-trip or at the fast charger to monitor what your battery actually uses or gains. Make more conscious decisions about when to charge at a fast charger depending of battery temperature and get more for your money. Plus, turn off your car and your prefered display screen and energy counter data are saved so the display is ready for your next drive.

Access Easily Hidden Informations of your EV!

  • No need to constantly mount / unmount / leave an expensive iOs / Android mobile phone / tablet on your car dash. Our system is fully automatic, you don’t need to think about it.
  • No need to waiste time and start an app like Torque Pro every time you want to access all this information. We know that in real life you don’t do it. But your missing useful data.
  • Avoid transferring files from devices to devices, searching the Internet, messing with PIDs / technical formulas, choosing what data you think is important or configuring application displays. We did the painful work for you and you will save time! (We know geeks do all of this anyway and will use multiple systems, but it’s fine!)
  • Above all: the data will easily be right in front of you all the time. You drive one of the most advanced electric vehicule and you deserve to know what going on.

Get a compatible Bluetooth OBDII Adapter & Get Going!

EVOBD2 requires a Bluetooth OBDII compatible adapter dongle to get information from your car. See the full list of compatible Bluetooth OBDII adapters below. Purchase EVOBD2 alone if you want to get your compatible Bluetooth OBDII adapter dongle from sources like Amazon yourself or get the EVOBD2 Kit that includes an adapter with the EVOBD2 display. We recommend highly to choose a small adapter because you could damage the car OBDII port with your legs if you get a larger adapter. Also avoid adapters with a wake-up button or connect button on the face plate. You will want to avoid pressing this button to wake it up and use the EVOBD2 display everytime. The goal is that you should do the least operations at all to use the system! Also note that these adapters consume very little power and can be left plugged in your car without any worry. All the following compatible adapters are a good partner for EVOBD2 for a fully automatic operation.

Compatible Adapters:

Recommended adapters will give best performance and reliable communication being less susceptible to radio interferences

Attention – The following adapters are NOT compatible:

OBDLink 428101 MX+, Stanz Blue Mini ELM327 Supper Mini OBD2, Motopower MP69034 OBD2, Aermotor Bluetooth OBD2, Vgate OBD2 iCar2 ELM327, Golvery Car OBD ii for Android

Automatic Adapter Pairing

EVOBD2 pairs easily using a one button setup with the compatible Bluetooth OBDII adapter. It automatically searches, finds, deals with necessary PINs to learn and pair with your adapter and once connected, unless you change the adapter, never do the pairing process again. Just remember to disconnect other apps you were using with the Bluetooth adapter because the adapter talks to only one device at a time! You can always use your app again with the adapter if you feel nostalgic or to do something else!

EVOBD2 is Safe & Secure

EVOBD2 only looks at the data in your car and does absolutely not interfere with the vehicle operation. It is not designed to check or clear error codes. Use it as a very convenient tool to monitor and learn what your electric car is up to.

Now the Good Stuff – Meet the EVOBD2 Data Screens!

Heater ON

1: General Information

  • Battery state of charge (SOC) in %
  • Average Battery Module Temperature in C
  • Battery Power in kW
  • Indoor Temperature in C
Fast charging

Screen 1 is the main default information center useful to monitor the battery state of charge and temperature. If it is warm enough over around 16 Celsius the charging power will be better and higher than 26 Celsius the charging power will be very efficient. Power positive values discharging the battery are in red and power negative values while charging or regenerative breaking are in green.

Driving

2: High Voltage Battery

  • Battery DC Voltage in V
  • Average Battery Module Temperature in C
  • Battery Power in kW
  • Battery Heater 1 Temperature in C
Fast charging

Screen 2 let’s you dive a little more into the battery showing the battery DC voltage and also the battery heater temperature at the bottom. The higher the voltage, the stronger the battery is after a charge. The voltage then decreases as you use the car and the state of charge drops. The heater usually kicks in to improve charging performance at the fast charger and helps maintain the battery in cold weather specially if winter mode is enabled.

Aux bat discharging

3: 12 V Auxiliary Battery

  • Auxiliary Battery State of Charge in %
  • Auxiliary Battery Voltage in V
  • Auxiliary Battery Currrent in A
Aux bat charging

Screen 3 displays the state of the other smaller but important auxiliary battery of your vehicle. Without this useful battery, you won’t be able to drive. Normally auxiliary battery voltage should be over 13 V and it’s state of charge should vary between 60 % and 100 %. The main battery takes care of charging the auxiliary battery when needed. The display shows a positive current value in red while the auxiliary battery is discharging and a negative green value while it is being charged by the main high voltage battery.

4: Cumulative Energy

  • Cumulative Energy Charged in kWh
  • Cumulative Energy Discharged in kWh

Screen 4 let’s you monitor the total energy or cumulative energy charged (CEC) that was put into the battery either by charging or regenerative braking since day one. You also get the cumulative energy discharged while driving and using HVAC ventilation / heating. Again, if the battery gains energy the value is green and if the battery uses energy the discharged value is red. Note that the charged energy is always higher than the discharged energy because of the battery heat and other losses and also because your battery is not empty for you to drive!

Short drive

5: Energy Counter

  • Energy Charged Counter in kWh
  • Energy Discharged in kWh

Screen 5 is an energy counter that shows you the energy the battery used and/or gained for a specific event. This can be very useful for instance to see what energy you actually got at the fast charger or at your home charger. All you need to do is press the right button on this screen to reset the counter before the charge. Same idea before a short drive or a multiple days roadtrip, you reset the counter and you can monitor how much your battery worked for you. Note that on a regular drive, you will see that you gain a bit of energy due to regenerative braking. You can turn on and off the car, the counter information remains in memory. Also you can still change screens if you want to see something else, the counter still runs in the background.

6: SOH & Operating Time

  • Battery State of Health in %
  • Car Operating Time in hours & minutes

Screen 6 is not the one you most likely will spend a lot of time on, but nevertheless you will be interested to check it on a regular basis to know this important information about car, the state of health of your battery. A newer vehicle has an expected 100% state of health. This value may decrease with vehicule usage to represent the battery degradation over time. We added the operating time of the vehicule since day one so that you could make a note at what time (and at wich amount of km or miles driven) the battery starts to show signs of degradation.
