Circuit device for energy store, has voltage monitoring portion whose is connected to positive terminal of energy store and output terminal is connected with control terminal of controllable circuit breaker

摘要

The device has a diode (9) that is connected to a positive terminal (12) connected to enable charging of an energy store (1). A ground terminal (M) with a reference line (7) is connected for dispensing a charge interrupt signal from a voltage monitoring portion (11) to the controllable power switches (8). An input terminal (S) of the voltage monitoring portion is connected to the positive terminal of the energy store and an output terminal (OUT) of the voltage monitoring portion is connected with a control terminal (C) of the controllable circuit switch.
