SUPPLY ENERGY ARRANGEMENT AND METHOD FOR PROVIDING A SUPPLY ENERGY
First Claim
1. A supply energy apparatus, comprisingan input to which an energy source is coupled,an output for connection of a load,a first energy storage device that is coupled to the input and the output,a second energy storage device that is coupled to the output and, via a switch, to the input, anda control circuit that controls the switch such thatthe switch disconnects the second energy storage device from the input while the first energy storage device is being charged by the energy source to at least a second predetermined energy level and the second energy storage device has an energy level that lies below a first predetermined energy level, andthe switch connects the second energy storage device to the input if the energy source has charged the first energy storage device to at least a second predetermined energy level and the energy level of the first energy storage device does not fall below a first predetermined energy level.

13. A method for providing a supply energy, characterized in that
a first energy storage device is first charged from an energy source to increase its energy level, and if the first energy storage device has reached a second predetermined energy level, a second energy storage device is also charged from the energy source, wherein, in case the first energy storage device has discharged to a first predetermined energy level, the second energy storage device is disconnected from the energy source the period of time required to charge the first energy storage device back up to the second predetermined energy level.
