Abstract

The invention discloses a power supply system and an automobile. The power supply system includes: a power battery pack, including at least two battery modules connected through a switch module; an emergency control module connected with the switch module; and an emergency control module connected with the emergency control module At least one emergency trigger switch connected to the module; a solar low-voltage power supply device connected to the emergency control module; a battery management system BMS, connected to the emergency control module, the BMS is used to obtain the collision signal of the electric vehicle and the current vehicle speed signal, and send the collision signal and the current vehicle speed signal to the emergency control module; wherein, the emergency control module, according to the state of the emergency trigger switch, the collision signal and the current vehicle speed signal, Control the disconnection or connection of the switch module. In the embodiment of the present invention, the power battery pack is disassembled by controlling the disconnection of the switch module between the two battery modules, thereby realizing the safe high-voltage power-off of the vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supply, in particular to a power supply system and an automobile. Background technique [0002] Since electric vehicles involve high-voltage electricity, when the vehicle breaks down or has a traffic accident, irregular operations during maintenance or emergency rescue may cause vehicle failure, and there is also the risk of high-voltage electric shock, short circuit, etc. causing explosion and fire. For this reason, emergency maintenance switches are arranged in the battery packs of some vehicles, but the emergency maintenance switches are directly connected to the high-voltage power supply, which requires professional operation, which has great risks and limitations; at the same time, the emergency maintenance switch is used to disconnect the battery The battery pack is positive and negative, but it cannot avoid the internal short circuit of the battery pack caused by external for...
