The invention discloses a safety protection method, system and device for a new energy vehicle and a storage medium, and belongs to the technical field of vehicles. The method is applied to a new energy automobile, and the new energy automobile comprises an ACU, a BMS, an MCU and a CCU. Comprising the steps that an ACU conducts collision detection on the new energy automobile, and when it is detected that the new energy automobile collides, collision signals are sent to a BMS, an MCU and a CCU; the BMS disconnects a first high-voltage loop in the BMS based on the collision signal; the MCU performs power-off operation on a motor of the new energy automobile based on the collision signal; the CCU determines the charging state of the new energy automobile; and under the condition that the charging state of the new energy automobile is charging, the new energy automobile is controlled to stop charging based on the collision signal. When the new energy automobile is collided, the BMS, the MCU and the CCU carry out power-off operation on the high-voltage loop and the high-voltage component, so that the safety of the new energy automobile is improved.
