Claims

1-10. -10. (canceled)

11. A mobile energy supply device for an electric starter for starting an internal combustion engine, comprising:

a battery; and

at least one capacitor connectible in parallel to the battery.

12. The mobile energy supply device of claim 11, wherein at least one capacitor is configured as a multilayer capacitor or an ultracap capacitor.

13. The mobile energy supply device of claim 11, wherein the energy supply device has multiple capacitors, which are arranged in multiple capacitor blocks.

14. The mobile energy supply device of claim 13, wherein the individual capacitor blocks are connectable and disconnectable in a targeted manner.

15. The mobile energy supply device of claim 11, wherein the energy supply device has a charger, which is configured for charging the battery.

16. The mobile energy supply device of claim 11, further comprising:

a resistor, which is connectible to the capacitors so that the capacitors are discharged via the resistor.

17. The mobile energy supply device of claim 11, further comprising:

a protection against polarity reversal, which is configured so as to at least one of interrupt a current flow and output an acoustic/visual warning signal if the mobile energy supply device is connected to the electric starter in reverse polarity.

18. The mobile energy supply device of claim 11, further comprising:

an electronic control circuit configured to control and monitor the operation of the energy supply device.

19. A method for operating an electric starter for starting an internal combustion engine, the method comprising:

connecting a battery to the electric starter;

connecting at least one capacitor to the battery to charge the capacitor; and

connecting the capacitor and the battery to the electric starter to drive the electric starter for starting the internal combustion engine.

20. The method of claim 19, further comprising:

discharging the capacitor via a resistor after the start of the internal combustion engine.
