Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 2, it is a schematic structural diagram of an embodiment of a power distribution circuit for a passenger car provided by the utility model; in this embodiment, a power distribution circuit for a passenger car includes:

a main fuse, which has a first end and a second end, the first end is connected to the output end of the generator, and the second end is connected to the battery;

The first type of load group 4 is connected to the first end of the main fuse;

The second type of load group 5 is connected to the second end of the main fuse.

Among them, the second load group 5 includes: engine control module, vehicle body control module, main relay, automatic transmission control module, brake switch, ignition switch power supply, ignition coil, fuel injector, oil pump, starter solenoid valve, sensor At least one of , actuator, instrument electrical box main power supply-1, intelligent entry and start system (Passive entry & push start, PEPS), wiper motor and low beam.
