Switching arrangement for a motor vehicle and motor vehicle driven at least partially electrically

A switching arrangement for a motor vehicle powered at least partially electrically, comprising:

• at least one inverter for converting a DC voltage of a high-voltage battery into a multi-phase AC voltage for a travel drive;
• at least one intermediate circuit capacitor connected to the inverter;
• and
• at least one pre-charge resistor, wherein, in a pre-charge mode, the pre-charge resistor serves to prevent current spikes during charging of the at least one intermediate circuit capacitor and, in a heating mode, serves for heating a coolant,
• wherein electrical current flows through the inverter in both the pre-charge mode as well as in the heating mode,
• wherein the inverter provides a high-voltage short circuit for the electrical current flow in the heating mode so as to heat the coolant,
• wherein the inverter electrically separates the high-voltage short circuit for the electrical current flow in the pre-charge mode;
• and
• wherein the high-voltage short circuit is provided by a switch for controlled periods of time such that the high-voltage short circuit is repeatedly provided according to a timing parameter and then broken according to the timing parameter.
