About this app

Check battery health, monitor temperatures, extract energy use, read error codes, and much more.

Soul EV Spy lets the owner of a Kia or Hyundai electric car view detailed information about their electric car's main battery, by plugging an inexpensive Konnwei KW902 ELM-327 v1.5 Bluetooth OBDII adapter into the standard OBDII port of the car. The app cannot modify any settings in the car. The app only reads data from the car, via the OBD-II dongle, displaying and saving data files. It does not write settings to the car.

A short users' guide and FAQ is available here:

Konnwei KW902 ELM-327 v1.5 Bluetooth adapters are available for around $10-$30, and you need one, for Soul EV Spy to fetch data from your car.

NOTE: The app does not support BLE adapters. And most of the many ELM-327 v2.1 adapters does not work with the app! Many ELM327 OBDII Bluetooth adapters are incompatible with the app, regardless of price. The only recommended dongle is the Bluetooth Konnwei KW902, because it supports all the needed ELM commands to communicate with the car systems, and it is the OBD-adapter that works most reliably, of all the tested adapters. It is not expensive.

This app is communicating with systems in the car, which potentially can cause the car to behave different from its normal behaviour. This app is not endorsed or approved by Kia, Hyundai or the companies that produce the systems in the car. If you choose to use this app, you alone are responsible for any and all consequences of doing so.

The app requests access to the device file system. If you grant access, the app will store data in files in the Download catalog on the device, for later replay in the app, or for the user to use in other apps, e.g. a spreadsheet, for data analysis, graphs etc.

This app requests access to location, in order to request locations of nearby DC-chargers, to calculate car speed, and to record the location for each reading of car data in the .csv data-file.

The app texts are by default displayed in english, or in the prioritized system language of the phone, if one of these:
