The arrangement (3) has three storage elements (10) comprising two rechargeable energy storages (8, 9), which are connected parallel to each other. One of the energy storage is designed such that certain minimum amount of electric charge of the energy storage is not less than minimum charging voltage of another energy storage. The certain minimum amount of electric charge i.e. minimum capacitance, of the former energy storage is 1 ampere-hour. A diode (12) i.e. quasi diode, and an electrical switching unit (16) are connected between the energy storages. The memory elements are designed as lithium memory elements, lithium titanate memory elements, nickel metal hydride memory elements and lithium iron phosphate memory elements. The energy storages are designed as lead acid battery and a lithium battery, respectively. |
