The invention relates to a wide-voltage-output new energy automobile charging pile device which comprises an input detection circuit, a power supply protection circuit and a driving output circuit. According to the wide-voltage-output new energy automobile charging pile device, the input detection circuit firstly achieves charging signal input through resistor voltage division, then a field effect transistor is embedded, input high voltage is divided into low voltage to be processed, and the defect of a charging pile in the aspect of low-voltage output is overcome. The power supply protection circuit ensures stable voltage output by controlling the state of a switching tube of the field effect transistor. The driving output circuit adopts high-frequency driving, so that field effect transistor is used as a driver to achieve high-reliability rapid turn-off, the turn-off loss can be reduced, the wide output characteristic of the charging pile is realized, and the efficiency of the charging pile is effectively improved.
