<p>In a method for detecting an overload situation in a battery-operated device having an electric motor, a load current of the electric motor is ascertained and used to deduce a thermal overload of the battery in such a manner, that, starting out from a static temperature limit, a temporally variable, maximum permissible temperature limit for the battery is calculated using a specifiable function dependent on the ascertained load current. The calculated, variable temperature limit is compared to a current, measured temperature of the battery, and a thermal overload of the battery is deduced from the result of the comparison.</p> |
