Assess the battery's charge status


Note:

Battery charge status is determined by the system APM (Advanced Power Management). both when driving and when the car is stationary.

During driving:

When the vehicle is stationary the resting current is measured cyclically to identify energy loss. The measuring values are stored in the memory of the intelligent battery sensor and are transmitted to the engine control unit at the next engine start.

The engine control unit stores the following values for the battery charge status' history:

Test conditions:

Procedure:

  1. Start the function.

  2. The following data is read out from the intelligent battery sensor.

    • Currently registered battery capacity.

    • Odometer reading at last battery change.

    • Current odometer reading.

  3. For more information, press the button "YES" to show the following data.

    • Charge status for the last five days.

    • Histogram for charge status.
