The harness belongs to the Cables, Harnesses, and Connectors group, meaning it includes both the power cable section and dedicated terminals and connectors matched to the factory sockets in the BMW i3 I01. The cable’s construction is prepared for operation in the technical compartments of an electric vehicle, where variable temperatures, vibrations, and moisture exposure occur.
Key performance features of this harness include:
- factory connectors compatible with the BMW i3 I01 installation,
- appropriately selected conductor cross-section for traction battery loads,
- insulation adapted for operation in an automotive environment,
- cable geometry matched to the original routing path within the body.
Original BMW Origin and Part Number Compatibility
This component comes from the BMW parts line, ensuring consistency with the factory quality and safety standards used in the brand’s electric vehicles. The battery cable harness has a dedicated OEM part number and associated interchangeable numbers, allowing for precise verification of its compatibility with a specific BMW i3 I01 configuration in manufacturer catalogs or parts selection systems.
The presence of reference numbers also facilitates comparison with the currently installed component in the vehicle, which is particularly important when replacing components in high-current systems where maintaining full electrical and mechanical compatibility is required.
Condition, Service Application, and Benefits of Installation
The battery cable harness is offered in used condition, allowing for an economical replacement of a damaged or worn component while maintaining original BMW specifications. This is a practical solution in situations where the cable has suffered mechanical damage, connectors have melted, or the system was tampered with during previous repairs.
Choosing an original, used harness allows you to:
- maintain the factory integrity of the electrical system,
- preserve compatibility with BMW diagnostic systems,
- reduce service costs compared to a new part,
- minimize installation time thanks to plug-and-play fitment.
An additional benefit is the environmental aspect – the reuse of functional components aligns with the concept of sustainable operation of electric vehicles.
