An electric vehicle charger with anti-extrusion function comprises a charger body, a controller located in the charger body, and a storage battery and an alarm arranged in the charger body, wherein the two opposite sides of the charger body are provided with a pair of rigid anti-extrusion plates, and the periphery of the two anti-extrusion plates extends to the outside of the charger body, the left ends and the right ends of the two anti-extrusion plates are fixedly connected through a plurality of supporting rods, and pressure sensors are arranged at the contact parts of the anti-extrusion plates and the charger body. The pressure sensors are used for detecting a pressure signal and sending an overpressure electric signal to the controller when the pressure exceeds a set value. The controller is used for controlling the alarm to carry out local warning after receiving the overpressure electric signal, and the alarm is used for giving an alarm. The charger has an alarm function when encountering extrusion, so that the charger can prevent from being squeezed and destroyed by objects accumulated on the surface or the periphery of the charger.
