Device for storing energy has a storage cell with a power output for storing energy and a voltage converter with power input and output for converting an output voltage for the storage cell into a preset voltage.

摘要

A storage cell (SC) (22) has a power output (24,26) for storing energy. A voltage converter (VC) (40) has power input (42,44) and output (46,48) for converting an output voltage (Vcn) for the SC into a preset voltage (V0). A casing fitted with a power connector (30,32) houses the SC and the VC. The SC's power output links to the VC's power input. The VC's power output links to the power connector on the casing.
