Abstract
An electronic circuit (1) for charging a battery (15) of a blower filter device (20), which blower filter device (20) can be supplied with power from an external electric power source. The electronic circuit charging terminals for connection to poles of the battery via electric lines. A measuring device measures a charging current. A control unit receives a measured signal of the measuring device and monitors a flow of current through the lines and switches the circuit component to high resistance or opens the circuit in the absence of a charging current. A battery (15) of a blower filter device (20) is also provided as well as a blower filter device (20) for a blower filter system (30) as well as a method for charging a battery (15) of a blower filter device (20).
