The invention discloses a new energy automobile charging detection method and device, an on-cable control box and a medium. The new energy automobile charging detection method comprises the steps that when a new energy automobile is in a charging state and an L-phase relay and an N-phase relay are closed, whether sensor data are reliable or not can be checked by detecting a PE voltage value between the L-phase and a PE phase and an LN voltage value between the L-phase and the N-phase, and meanwhile when the sensor data are reliable, the new energy automobile is charged. According to the invention, whether the PE phase is broken or not can be accurately judged, so that the electric shock risk of personnel is greatly reduced, and whether the L phase and the N phase are installed in a wrong phase or not can be accurately judged, so that the function failure caused by the wrong phase is prevented. 本发明公开了一种新能源汽车充电检测方法、装置、缆上控制盒及介质。该新能源汽车充电检测方法包括：在新能源汽车处于充电状态且闭合L相继电器和N相继电器，通过检测L相与PE相之间的PE电压值以及L相与N相之间的LN电压值，可以校核传感器数据
