A method for protecting an on-board charging device includes the steps of detecting the phase and neutral voltages coming from the grid, detecting a current signal representing a compensation current generated by a compensation circuit, combining the phase voltages together so as to obtain a homopolar voltage signal, squaring the current signal and the homopolar voltage signal so as to obtain a first square current wave and a second square voltage wave, combining the first and second square waves together so as to generate an output signal having a first logic level when the first and second square waves are in phase and a second logic level when the first and second square waves are out of phase, generating a voltage increasing in proportion to the duration of each section of the output signal having the first value, comparing the voltage value with a limit value and generating an alarm signal when the voltage level exceeds the limit value.
