The invention discloses a new energy automobile drive motor high voltage terminal protection method and system. An obtained temperature signal on a high voltage terminal is converted into a target temperature signal capable of being read by a digital signal processor, and then the target temperature signal is judged to determine whether the high voltage terminal breaks down or not. When a judging result is that the high voltage terminal breaks down, a close command and a breakdown signal are sent, so that no current is transmitted in the high voltage terminal of a motor, the temperature drops, and finally the protection on the high voltage terminal is achieved.
