Abstract
The invention relates to a restart protection device () for a battery-powered electric hand tool (), comprising—a control capacitor (C) having a cathode and an anode, wherein the cathode can be connected to an earth connection () of the electric hand tool () and the anode can be connected via a battery pack interface () of the electric hand tool () to a connector wire () of a battery pack () of the electric hand tool (); —a controllable discharge circuit () designed for discharging the control capacitor (C), wherein a control input of the discharge circuit () can be connected via the battery pack interface () to a signal line () of the battery pack (); —a measuring device () designed to determine a charge state of the control capacitor (C); and—a control device () connected to the measuring device (), which control device is configured to inhibit start-up of the electric hand tool () if the charge state of the control capacitor (C) determined by means of the measuring device () is below a specified threshold value and an operating switch () on the electric hand tool () is pressed at the same time.
