Title:
FUSE BLOCK, VEHICLE-MOUNTED PROTECTION SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/217110
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a fuse block, a vehicle-mounted protection system and a vehicle. The fuse block is provided with a first circuit and a second circuit. The first circuit comprises multiple first protection branches connected in parallel, wherein the first protection branches are provided with fuse modules, and one end of each of the first protection branches is connected to a first power supply by means of the first power supply interface. The second circuit comprises a second power supply interface and multiple second protection branches connected in parallel, wherein each second protection branch is provided with at least two fuse modules connected in series, and one end of each of the second protection branches is connected to the second power supply through the second power supply interface. When the second protection branches are short-circuited, the arc discharge voltage of the arc discharge that connects the second power supply on the second protection branches and the second electric device exceeds the output voltage of the second power supply. The output voltage of the first power supply is lower than the output voltage of the second power supply. The embodiments of the present invention can reduce the development cost of fuse blocks of different voltage systems in the vehicle, and thus lower the development cost of the vehicles.
