Purpose and function in the powertrain

The inverter in the BMW i3 I01 Hybrid 60Ah Rex model is responsible for controlling the flow of energy between the traction battery, the electric motor, and the vehicle's auxiliary systems. As a component from the Alternators and generators category, it works with the charging and energy recovery system, stabilizing operating parameters under various loads and driving conditions.

In a range extender hybrid vehicle, a properly functioning inverter has a direct impact on:

• the smoothness of power delivery by the electric motor,
• the efficiency of recuperation during braking,
• the stability of high and low voltage power supply,
• safe cooperation with the battery management system.

Compatibility and vehicle integration

The offered inverter has been designed for full integration with the factory electrical architecture of the BMW i3 I01 in the 60Ah Rex hybrid version. The design, intended for use with an automatic transmission, enables proper communication with powertrain control modules and vehicle safety systems.

By using an original BMW solution, the module maintains:

• compatibility with factory wiring harnesses and connectors,
• cooperation with vehicle control unit software,
• operating parameters matched to the characteristics of the electric unit and battery.
