Elektrik: battery drain - eine Sammlung von Daten

[Erich]

Information zusammen getragen aus dem E31 8er board bei roadfly:

Since practically every hollow space within an 8/7/5 is host to a control unit, many with memory and sensors, it is no wonder the E31/32/34 has such a high resting current drain. About 1 amp/hour drain about every 20 hours. Here's the figures:
With the trunk/luggage compartment lights off:
1.) Driver's door open: 4.8 - 5.0 Amps
2.) Driver's door closed: 4.1 Amps for 20 seconds then reduced to approx. 450-470mA for next 16 mins. then reduced to approx. 50mA
With the trunk/luggage compartment lights on:
1.) Driver's door open approx. 6.1-6.4 Amps
2.) Driver's door closed--approx. 5.9-6.1 Amps for 20 seconds, then reduced to approx. 2.5 Amps for the next 16 mins, then reduced to approx. 50mA
