An improved arrangement for balancing a short term energy storage is disclosed. The short term energy storage includes a plurality of super capacitors being connected in series. According to the present invention,the arrangement includes a diode means, which is conductive in only one direction. This diode means is connected in parallel with at least two super capacitors of the plurality of super capacitors being included in the short term energy storage, and in a direction such that the diode means will be conducting if a polarity over the at least two super capacitors is reversed in relation to a polarity of a charging voltage having been used for charging the short term energy storage. |
