BMW 3: Designation and identification

Designation of electrical machines

The electrical machine designation is used in the technical documentation for clear identification of the electrical machine. However, the identification of the electrical machine is relevant for Service.

Identification of the electrical machine

The electrical machines have an identification to ensure clear identification and classification. This identification is also necessary for approval by government authorities. The identification of the electrical machines is equivalent to the identification of the combustion engines. The serial number of the electrical machine can be found under the electrical machine identification on the electrical machine. This consecutive number, in conjunction with the identification, permits clear identification of each individual electrical machine.

     Adapted control units

    It was necessary to adapt the IHKA to enable activation of the electric A/C compressor (EKK) in all operating conditions. The electric A/C compressor control unit communicates with the IHKA via the LIN bus. To be able to show additional displays for driving readiness, electric driving, brake ene
