Problems solved by technology
Several distribution boards are designed for the electrical appliances of the vehicle, and a large number of plug-in fuses are installed on the distribution boards to supply power for each electrical appliance, resulting in very messy wiring of the distribution boards
[0004] Moreover, the increasing number of electrical appliances not only brings complicated power supply connections, but also brings more hidden dangers to the safety of vehicle power consumption. The traditional fuse protection method has very limited effect on the safety protection of vehicle power consumption.
In addition, there are more and more electronic control units and circuits in the automotive electrical system, and the output voltage of the battery-generator is unstable, which is not suitable for directly supplying power to the controller circuit of the vehicle, and the power consumption of the electronic control unit needs to be regulated and converted
[0005] To sum up, the problems existing in the existing automobile power supply network are that there is no good vehicle power planning mechanism, the connection of the power supply system is messy, and there is no intelligent function to monitor and protect the power safety of the power supply system.

Description
technical field [0001] The invention relates to the field of automobile electrical technology, in particular to a power supply system for automobiles. Background technique [0002] The traditional automotive electrical system uses a battery-generator connected in parallel to provide power for the vehicle's electrical appliances. Three wires are drawn from the positive pole of the battery: one wire is directly connected to the starter; one wire is connected to the generator through a fuse; power supply line. After passing through the fuse, the power supply line of the body electrical appliance is further divided into three: normally on power wire, ACC power wire and ON power wire. Protect. [0003] The traditional power supply method has a simple structure and low cost, and is still widely used in automobiles to provide power supply for automobile electrical systems. The on-off control of electrical appliances is realized by components such as switches, relays, and distrib...
