BMW 3: Connections

BMW 3 Series G20 (2018-2025) Training manual / Electrical Machine / Design / Connections

Design
Connections, electrical machine

  1. Transmission bell housing
  2. Temperature sensor
  3. Coolant ducts
  4. Connection for coolant (transmission oil)
  5. Electrical connection, rotor position sensor
  6. High-voltage connection

There are four connections of the electrical machine on the housing of the automatic transmission for the following components:

  • Temperature sensor
  • Cooling (by transmission oil)
  • Rotor position sensor
  • High-voltage cables

High-voltage connection

Design
High-voltage connection, electrical machine

  1. High-voltage connection
  2. High-voltage connector

Electrical energy is fed to the coils of the electrical machine via the high-voltage connection. The high- voltage connection connects the Electrical Machine Electronics to the electrical machine via a three- phase, shielded high-voltage cable.

The high-voltage connectors are screwed on to the Electrical Machine Electronics and the electrical machine.

High-voltage cables must not be repaired. In the event of damage, the line must always be replaced!

    The G20 PHEV is a Full-Hybrid Generation 4.0 vehicle. In contrast to generation 2 and 3 hybrid vehicles, electrical driving is possible in the G20 PHEV at much higher speeds and with a higher range.

     Cooling

    To guarantee the thermal operating safety of the electrical machine in every situation, it is cooled with coolant in the G20 PHEV. For this, the electrical machine is integrated in the coolant

     Load point increase

    Raising the load of the combustion engine at consistent engine speed is called load point increase. This results in an increase in performance and the option to operate the combustion engine in the optimal range. The arising resistance, which counteracts the combustion engine, must be compensate
