The invention discloses a high-voltage safety protection method for a new-energy vehicle. The method comprises the steps of carrying out the main positive and main negative double control of a DC charging socket interface, a battery electric heating interface and a high-voltage drive motor in a high-voltage box according to the application of a high-voltage component and the division of the post-or severity degree after the adhesion of a relay so as to protect the high-voltage component. According to the invention, a dual-protection control method of the main positive relay and the main negative relay is adopted for the high-voltage component of the new-energy automobile; the dual-protection control method for the high-voltage component can effectively prevent the main positive relay or the main negative relay from being damaged due to the fact that the main positive relay or the main negative relay are adhered and cannot be disconnected in time due to failure while the use safety of the high-voltage component of the new-energy automobile is ensured.

    本发明公开了一种新能源整车高压安全保护方法,根据高压部件的用途以及继电器发生粘连之后的后或严重程度划分,将高压箱内直流充电插座接口、电池电加热接口、高压驱动电机增加主正主负双重控制来对高压部件进行保护。本发明通过对新能源汽车高压部件采用主正、主负继电器的双重保护控制方法,在确保新能源汽车高压部件使用安全的同时,对高压部件双重保护控制的方法,能够有效避免主正继电器或主负继电器因故障粘连无法及时断开而导致高压部件损坏。
