The invention relates to the technical field of automobiles, in particular to an electric automobile high-voltage framework, an electric automobile, an adhesion fault detection method and a medium. The main relay is connected with the pre-charging circuit in parallel, and one end of the main relay and one end of the pre-charging circuit are connected with the positive electrode or the negative electrode of the power battery; one end of the fast charging relay is connected with the positive electrode or the negative electrode of the power battery, and the other end of the fast charging relay is connected with the positive electrode or the negative electrode of the fast charging port; and the battery management system is respectively connected with the pre-charging circuit, the main relay and the quick-charging relay and is used for controlling the pre-charging circuit, the main relay and the quick-charging relay to be switched on or switched off. Therefore, the problems that in the prior art, due to the fact that the number of relays and voltage detection circuits is large, the cost of a high-voltage framework of the electric vehicle is high, the efficiency of determining adhesion faults is low, and the use experience of a user is reduced are solved.
本申请涉及汽车技术领域,特别涉及一种电动汽车高压架构、电动汽车、粘连故障检测方法及介质,其中,架构包括:动力电池;预充电路和主继电器,其中,主继电器与预充电路并联,主继电器与预充电路的一端与动力电池的正极或负极相连;快充继电器,其中,快充继电器的一端与动力电池的正极或负极相连,快充继电器的另一端与快充口的正极或负极相连;电池管理系统,其中,电池管理系统分别与预充电路、主继电器和快充继电器相连,控制预充电路、主继电器和快充继电器闭合或断开。由此,解决了相关技术中由于继电器和电压检测电路的数量较多,容易导致电动汽车高压架构的成本较高且确定粘连故障的效率较低,降低用户的使用体验等问题。
