The invention discloses a high-voltage maintenance switch of a new energy vehicle, aiming at solving the problem that an air switch is used for controlling the connection and disconnection of a battery power supply system of the whole vehicle, the stability is poor, the connection cannot be performed for a communication circuit of the whole vehicle, a feedback signal cannot be supplied to the whole vehicle control system after a main circuit is broken, and the safety of driving and using is influenced. The high-voltage maintenance switch box of the new energy vehicle is that a first manual maintenance switch set, a first fuse and a low-pressure signal connector interface are connected to form a first high-voltage large-current circuit; a second manual maintenance switch set, a second fuse and a low-voltage signal connector interface are connected to form a second high-voltage large-current circuit; the first manual maintenance switch set, the second manual maintenance switch set and the low-voltage signal connector interface are connected to form a low-voltage interlocking circuit; a low-pressure signal connector interface is connected with a communication management system of the whole vehicle. According to the high-voltage maintenance switch box of the new energy vehicle, a high-voltage interlocking low-voltage control signal is output to the communication management system of the whole vehicle, so that the reliability and the safety of a high-voltage electrical control system of an electric automobile can be effectively improved.
