The invention discloses a vehicle high-voltage power distribution system. The system comprises a positive bus and a negative bus which are connected with a battery pack and a load, and no contactor isarranged between the positive bus and the positive electrode of a charging port or between the negative bus and the negative electrode of the charging port, so that the cost is reduced. The inventionfurther discloses a vehicle high-voltage safety control method. The method comprises the steps that first information representing the opening and closing state of the charging port cover, second information representing whether the contactor is sintered or not, third information representing whether electric leakage exists in the high-voltage power distribution system or not and fourth information representing the vehicle speed are obtained and analyzed; and when the contactor is sintered and/or electric leakage exists in the high-voltage power distribution system, the charging port cover isin an opening state, and the vehicle speed is not larger than a threshold value, the vehicle is controlled to be in a non-high-voltage state to guarantee personnel safety.

    本发明公开了一种车辆高压配电系统,该系统包括连接电池包和负载的正极母线与负极母线,正极母线与充电口的正极之间以及负极母线与充电口的负极之间中的一者上未设置接触器以降低成本;还公开了一种车辆高压安全控制方法,其包括获取并分析表征充电口盖的开闭状态的第一信息、表征所述接触器是否烧结的第二信息、表征所述高压配电系统是否存在漏电的第三信息以及表征车速的第四信息;当接触器烧结和/或高压配电系统存在漏电,且充电口盖为打开状态以及车速不大于阈值时,控制车辆处于非高压状态以保证人员安全。
