Emergency-Mode Functions

Emergency-Mode Functions

Battery Temperature Sensor

In the event of a defective sensor, a short circuit or an implausible value, the substitute value of 20 °C is assumed. This corresponds to a fixed charge voltage of 14.3 V at the battery.

Battery capacity (SoC) is calculated using the substitute value.

Battery Switch

If a fault is detected in the battery switch, the Power Module switches to Storage mode as if the switch were in the "OFF" position.

Terminal 15w

Shut-down of the PM in the absence of terminal 15w is prevented by the following duplicated signals:

- Terminal 15 (from CAS via bus link)
- Road speed >2 km/h (from DSC via bus link)
- System voltage >13.2 V (PM central battery voltage notification)

Bus Communication

If bus communication is not possible, all information is "frozen."
