ABSTRACT:
An energy storage device that includes capacitor cells of a first type having a first internal resistance and capacitor cells of a second type having a second internal resistance which is higher than the first internal resistance. Further, there is a detection unit that detects a voltage value between two opposing ends of at least one of the capacitor cells, or a voltage detection switching unit that integrates a switch arranged between two opposing ends of at least one of the capacitor cells.
