Starting and Charging: Description and Operation

Starting The Vehicle

When the ignition is switched on (terminal 15 on), the 12-volt starter battery initially supplies power to the vehicle electrical system and the control units. The contactors in the E-box are only activated when the engine starts (terminal 50). A DC voltage of 288 V is then supplied to the power electronics via the high-voltage cable connections.







The combustion engine only starts when the conditions for electric driving are no longer fulfilled:
- Engine temperature 90° F. (32° C.) or lower
- Charge state of the traction battery is too low to drive solely under electric power
If the charge state of the high-voltage battery is too low to start the combustion engine, Porsche After Sales Service has the option of charging the HV battery using an appropriate charging device.

The high-voltage battery can be charged by the charger only when its charge state is below 30%.
The 12-volt battery can be charged via the 12-volt terminal using a conventional external charging concept.
