Capacitive type electric energy accumulator of high capacity
First Claim
Patent Images
1. An electric energy accumulator of capacitive type for use in an electrically motorized turret of a tank, said turret comprising a generally circular rotatable member, the accumulator comprising:
- a plurality of cases each defining a circular sector, said cases being placed side by side so as to form at least a partial ring mounted to the generally circular rotatable member of the turret, heat dissipation shunts integrated in each said case, a plurality of electrochemical capacitors connected in parallel and disposed inside each said case, each said case further housing an over-voltage detection circuit and a circuit for controlling discharge of the capacitors into the heat dissipation shunts in the case, whereby the capacitors are discharged when an abnormal over-voltage is detected, thereby avoiding explosion of the capacitors and resulting damage in proximity to the turret of the tank.

- 2. An electric energy accumulator according to claim 6, further comprising a plurality of fuses and being characterized in that the capacitors are distributed inside the respective cases in a plurality of separate batteries (A1 . . . A4) each said battery being electrically connected with one said fuse (F) such that a short circuit in one of said capacitors causes destruction of the fuse (F) of the corresponding batter (A1 . . . A4) and such that the remaining ones of said batteries (A1 . . . A4) continue operating.
