Abstract
A protection circuit for a simulated battery cell having an output comprising an output voltage includes: at least one MOSFET connected to the output of the simulated battery cell for short-circuiting the output of the simulated battery cell; a capacitor connected to a gate electrode of the at least one MOSFET; an overvoltage detection device configured to charge the capacitor with the output voltage based on an overvoltage limit of the output voltage being exceeded; and a threshold voltage detection device configured to release the gate electrode based on a threshold value of a voltage at the capacitor not being reached.
