What’s New in EVScanner: Diagnostic and REx Enhancements

With the latest EVScanner update, three new features have been added that focus on deeper diagnostics and more detailed vehicle data, especially for BMW plug-in hybrids (PHEVs) and the BMW i3 with Range Extender (REx).

Individual Battery Cell Voltages

EVScanner can now read and display individual high-voltage battery cell voltages for vehicles equipped with the SME (F15) control unit. This applies primarily to BMW plug-in hybrid models such as the BMW 330e or BMW 530e.

Until now, battery data was typically limited to overall values. With this update, you can see how each individual cell behaves, which makes it easier to identify voltage differences within the battery. This information can help with a more informed assessment of battery condition over time, especially as the vehicle ages or when evaluating a used car.

Detection of Defective Cells per Battery Module

In addition to showing individual cell voltages, EVScanner now supports reading reported cell defects per high-voltage module on vehicles with the SME (F15) control unit.

The app provides an overview of all modules and indicates whether a module contains a defective cell. This feature is useful for understanding how issues are distributed across the battery system rather than looking at isolated values. It can also help when discussing battery condition with a workshop or when checking a vehicle before purchase.

Additional Range Extender Data for BMW i3 (REx)

For the BMW i3 equipped with the Range Extender (REx), EVScanner now reads additional REx-specific data and shows it in the dashboard view.

Newly available values include coolant temperature, engine torque, and engine speed. These parameters make it easier to understand how the Range Extender operates in different driving situations and provide more context when it is active, especially on longer trips.

Available Now

All three features are available in the latest version of EVScanner.

Visit EVScanner on the Apple App Store to get started.

As always, you can use the free version to check vehicle compatibility, and unlock full functionality via an in-app purchase once supported.
