Purpose and Function in the BMW i3 Hybrid System

The presented REME module for BMW i3 I01 LCI Rex Hybrid is the central element controlling the operation of the combustion engine generator in range extender versions. It is responsible for coordinating the operating parameters of the combustion unit, collaborating with the high-voltage system, and integrating with other vehicle control units, which translates to predictable vehicle behavior under various operating conditions.

As a component from the Computers and Control Units group, the module communicates with the vehicle's data bus, monitoring, among other things, drive modes, response to load, and interaction with safety and energy management systems. This ensures the consistency of the entire hybrid system's operating logic.

Benefits of Using an Original REME Module

Using an original REME control unit in a BMW i3 with a range extender allows for maintaining factory drive parameters and reducing the risk of communication errors between control units. This is particularly important in electric vehicles with complex electronics, where each module is precisely matched to the car's configuration.

• maintaining compatibility with factory software and vehicle network architecture,
• stable operation of the Range Extender system without unwanted error messages,
• better predictability of drive response in hybrid modes,
• reduced adaptation and coding issues compared to non-original solutions.

This component comes from the BMW segment, which promotes proper integration with the electrical and mechanical systems of the specific i3 I01 LCI Rex Hybrid model version.

Technical Characteristics and Fitment

The REME module is designed as a dedicated control unit for the range extender system, with appropriately prepared connectors and logic for interaction with other onboard computers. This ensures the consistency of the vehicle's configuration, including correct handling of driving modes, diagnostics, and communication with service systems.

The product has an assigned OEM part number and related interchangeable numbers, which facilitates verification of compatibility by manufacturer identifiers and allows for selecting the correct control unit for a specific equipment version. If in doubt, it is recommended to compare the markings with the currently installed module or consult based on vehicle data.

Condition, Application, and Installation Recommendations

The offered REME control unit is a used component, allowing for economical repair of the hybrid system while maintaining the original manufacturer's specifications. This type of solution is often chosen in case of drive electronics failure, where the priority is a combination of correct operation and reasonable service costs.

Due to the nature of this module from the Computers and Control Units group, installation and potential programming by a workshop experienced with BMW i3 electronics are recommended. Proper installation, coding, and adaptation are crucial for seamless integration with other vehicle systems and to avoid secondary faults.
