FBATT – HV BATT INFO for FORD is a dedicated Android diagnostic application designed for monitoring the high-voltage (HV) battery system in Ford electric and hybrid vehicles. Whether you’re an EV owner, mechanic, or automotive enthusiast, FBATT gives you direct insight into your battery’s health and real-time operating parameters — data that is typically only accessible with professional workshop equipment.
What Is FBATT?
FBATT is a purpose-built diagnostic tool that communicates directly with the Battery Management System (BMS) of Ford electric vehicles via a Bluetooth OBD2 interface. It reads live data from the HV battery module, enabling users to monitor cell voltages, state of charge, temperature distribution, and other critical parameters — all from an Android smartphone or tablet.
The app is developed by Marcin Węgrzyn and is available on Google Play.
Supported Vehicles
FBATT is optimized for Ford electric vehicles based on the Mustang Mach-E platform. The following models are fully supported:
- Ford Mustang Mach-E
- Ford E-Transit
- Ford E-Transit Courier
- Ford Puma Gen-E
The application can also communicate with Ford hybrid vehicles equipped with an HV battery, though the information read may be incomplete depending on the model. Please note that electric vehicles based on the Volkswagen platform (such as Ford Explorer EV and Ford Capri BV) are not supported.
Required Hardware: Diagnostic Interface
For FBATT to function correctly, you need a compatible ELM327/STN Bluetooth diagnostic interface that supports the MS-CAN (Medium Speed CAN) bus protocol used in Ford vehicles. Standard generic ELM327 adapters are not sufficient — you must use a device with confirmed MS-CAN support.
The following adapters have been confirmed to work correctly with FBATT:
- Vgate vLinker FD ELM327 – recommended, supports MS-CAN out of the box
- OBDLink MX+ – professional-grade adapter with full MS-CAN support
How to Connect and Launch the App
Follow these steps to establish a successful connection between FBATT and your vehicle:
- Pair the adapter via Android Bluetooth settings.
Before opening the app, plug the ELM327/STN adapter into your vehicle’s OBD2 port. Then go to your Android device’s Settings → Bluetooth, scan for devices, and pair the adapter. Complete this step first — the app does not handle pairing itself. - Turn on the vehicle ignition.
The car must have its ignition switched on for the OBD2 communication to be active. Without the ignition, the diagnostic bus is inactive and no data can be retrieved. - Open FBATT and select your Bluetooth device.
Launch the app and navigate to Settings. With Bluetooth enabled on your Android device, select the previously paired adapter from the list of available Bluetooth devices. This tells the app which interface to use. - Tap the Bluetooth icon on the main screen to connect.
Return to the main screen of the app and tap the Bluetooth plug icon. The app will initiate communication with the adapter and, through it, with the vehicle’s BMS. Once connected, live battery data will begin to populate the screen.
