Technical characteristics and compatibility

The offered BMW battery wiring harness comes from a group of original parts designed specifically for the requirements of the i3 I01 model with an electric drive. The wire cross-sections, connector types, and installation routing are adapted to the current loads and operating conditions in the battery compartment and the vehicle's installation tunnels.

The part is intended for service applications in BMW vehicles where full compliance with factory technical documentation and the parameters of the charging and power supply system is required. As a result, the harness can be used both for standard replacement of a damaged section of the installation and for more extensive repair work within the traction battery.

Condition, origin, and advantages of using a used part

The product is in the Charging cables category and is offered as a used part, which allows for cost-effective repairs while maintaining the manufacturer's original specifications. Using a component dismantled from the same model line allows for:

• maintaining the factory routing of the harness in the vehicle,
• matching the original brackets and mounting points,
• reducing service costs while maintaining compliance with BMW solutions.

For workshops specializing in the maintenance of BMW electric vehicles, using an original battery wiring harness is beneficial in terms of safety, repair repeatability, and subsequent diagnostics.

Selection by numbers and purchase support

The BMW i3 I01 electric battery wiring harness has a dedicated OEM part number and associated interchangeable numbers, which facilitates unambiguous identification of the part in service catalogs and parts selection systems. When matching to a specific vehicle, it is worth using the manufacturer's numbering or data from service documentation to ensure full compatibility with the drive version and battery configuration.
