Energy storage device has decoupling element which is electrically connected in series with connecting element so that electric current from negative connection pole to positive connection pole is blocked

摘要

The device (10) has a positive connection pole (16) and a negative connection pole (18) which are electrically connected to storage element (12) for charging and discharging the storage element. A connecting element (22) is connected with the connection poles. The electric current (I1) from positive connection pole is provided to negative connection pole, if the stored electrical energy exceeds predefined value. A decoupling element (24) is connected in series with the connecting element so that electric current from negative connection pole to positive connection pole is blocked.
