Abstract

A safety discharge apparatus for an electrical storage element includes a load device for discharging the electrical storage element connected to the safety discharge apparatus via input connections. The apparatus includes a clocked switching device connected to a control device that serves to produce and interrupt a discharge current via the load device and the storage element, and a voltage detection device that detects a storage voltage of the electrical storage element to be discharged. The voltage detection device is connected to a discharge condition monitor that checks a dischargeability of the electrical storage element. An operating method for a safety discharge apparatus is also disclosed.
