1. An electric vehicle charging plug comprising:
a housing configured to connect to an electric vehicle,
a main housing,
a sensor comprising at least one conductive path embedded in a wall or arranged on the surface of the housing and/or main housing, and
a control unit,
wherein the sensor is configured to:
detect a crack of the housing and/or the main housing; and
measure at least one characteristic of the at least one conductive path, wherein detecting the crack of the housing and/or the main housing is based on the at least one characteristic of the at least one conductive path changing upon at least partial breakage of the at least one conductive path, wherein the at least one conductive path is an electric conductive path, and wherein the control unit is configured to measure impedance, inductance and/or capacitance of the electric conductive path.
