Jump-starting arrangement for a motor vehicle

A jump-starting arrangement for a motor vehicle equipped with an engine control unit and a starter for an internal-combustion engine, the jump-starting arrangement comprising:

• first and second partial onboard power systems, each of the first and second partial onboard power systems being equipped with at least one rechargeable electric energy accumulator;
• an electric separator element by way of which the first and second partial onboard power systems are mutually coupled;
• and
• an external current source,
• wherein the first partial onboard power system has a first jump-starting base and the second partial onboard power system has a second jump-starting base, the first and second jump-starting bases being galvanically separated from one another,
• wherein the first jump-starting base is physically accessible externally from the motor vehicle so as to be coupleable directly to a terminal of a first jump-starting cable during a jump start of the internal-combustion engine of the motor vehicle,
• wherein the second jump-starting base is physically accessible externally from the motor vehicle so as to be coupleable directly to a terminal of a second jump-starting cable during the jump start of the internal-combustion engine of the motor vehicle,
• wherein the first partial onboard power system and second partial onboard power system are configured to couple in parallel with the external current source by virtue of a parallel junction of the first jump-starting cable and the second jump-starting cable such that the external current source charges each of the respective accumulators,
• wherein each of the first and second jump-starting bases are distinct from respective terminals of each of the at least one rechargeable electric energy accumulators.
