The invention relates to an electrical energy storage unit on EDLC basis comprising a first number of electrochemical double-layer capacitors (4). According to the invention the energy storage unit is characterised in that a second number of sensor units (2) is provided, wherein each sensor unit (2) is associated with a particular one of aid capacitors (4) of the electrical energy storage unit, is adapted to sense current and voltage values over the associated capacitor (4) and its temperature, and comprises a wireless transmitter for the data representative of said voltage, current and temperature values, and in that means for storing (6, 10) the data of each sensor unit as time series are provided, wherein said means for storing is associated with a wireless transceiver (8) for receiving said data representative of said voltage, current and temperature values from each sensor unit and for wireless transmission of the time series data stored in means for storing upon receiving a transmission request signal from a remote controlling unit. |
