What does automotive circuit and power distribution device include

power distribution system power distribution system includes central junction box, circuit switch, insurance Devices, plug-ins and wires, etc., to ensure the reliability and safety of the line work.

Generally, it includes wind window wiping and cleaning device, wind window defrosting (anti-fog) device, air conditioning device, audio device, etc. The more advanced models are also equipped with electric window lifting devices, electronic door locks, electric seat adjustment devices and electric remote control rearview mirrors, etc. Electronic control airbags are included in the electronic control system.

The power distribution system includes central junction boxes, circuit switches, safety devices, plugs and wires, etc. to ensure the reliability and safety of line work.

The whole vehicle circuit is composed of power supply circuit, start circuit, ignition circuit, lighting and lighting signal device circuit, instrument information system circuit, auxiliary device circuit and electronic control system circuit.

There are many types and quantities of electrical equipment in modern automobiles. In general, it can be roughly divided into three major parts, namely power supply system, electrical equipment and power distribution device, and whole vehicle circuit. Composition of automotive electrical equipment 1. Power supply system The main functions of automobile power supply system are power generation, power storage and power supply.

What is the circuit principle of a car?

1. What is the principle of automobile circuits? Automobile circuits are all DC, and single-wire parallel circuits are implemented. Electrical appliances only need one external power cord. The automotive circuit is a single-wire parallel circuit. Generally speaking, there are still series, parallel and mixed circuits in local circuits.

2. Power supply is the battery and bus. Use electric horns, headlights, fog lights, taillights, instruments and instrument lights, turn signals... Understand the general law of the automobile circuit diagram. The power supply part to the wires of various electrical fuses or switches are the public fire wires of electrical equipment. In the circuit schematic diagram, it is generally drawn in the upper part of the circuit diagram.

3. The circuit of the car is all DC, and the single-wire parallel circuit is implemented.Electrical appliances only need an external power cord. The car adopts a single-wire parallel circuit. Generally speaking, local circuits still have series, parallel and mixed circuits.

4. When the external circuit energizes the excitation winding through the brush, a magnetic field is generated, so that the claw pole is magnetized into N pole and S pole. When the rotor rotates, the magnetic flux changes alternately in the stator winding. According to the principle of electromagnetic induction, it can be seen that alternating induced electromotive potential is generated in the three-phase winding of the stator.

5. Hello, the automobile circuit is a complex control system composed of power supplies, wires, switches and various electrical appliances. Its working principle is very similar to the function of the human nervous system.

6. The modern air conditioning system is composed of refrigeration system, heating system, ventilation and air purification device and control system. The control principle is as follows: Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into high-temperature and high-pressure gas and discharges it into the compressor.

What are the characteristics of the automotive circuit

On the one hand, the automotive circuit has the commonality of the general circuit, and is also composed of power supplies, electrical appliances, switches, fuses, wires, etc. On the other hand, it has its own peculiarities and five characteristics. Let's first take a look at the characteristics of automobile circuits and what are the characteristics of automobile circuits. The first point is two power supplies.

The characteristics of automobile circuits mainly include the following aspects: two power supplies: the so-called two power supplies refer to the two power supplies of the storage battery and the generator.

Automotive circuits are characterized by low-voltage power supply, DC power supply,It has two power supplies, electrical equipment in parallel, equipped with an insurance device, a single-wire system, a negative electrode iron, a combination of a unit circuit, and a car line with color and identification characteristics. Low-voltage power supply. The rated voltage of automobile circuits generally has two types: 12V and 24V.

What does the automobile circuit consist of?

The basic components of automobile circuits are: automobile power supply; automobile wires; automobile electrical appliances; automobile electrical appliances switches; automobile safety devices; automobile electrical appliances intermediate devices.

Automotive circuits are mainly composed of power supplies, circuit protection devices, control components, electrical equipment and wires. The automobile circuit implements a single-wire parallel circuit. Generally speaking, there are still series, parallel and hybrid circuits in local circuits.

The automobile circuit is mainly composed of power supply, circuit protection device, controller, electrical equipment and wires.

Basic knowledge of automotive circuit

1. Power supply circuit, also known as charging circuit, is a circuit composed of battery, generator, regulator and charging indicator device, etc. Electricity distribution (power distribution) and circuit protection devices can also be classified into this Circuit. A starter circuit is a circuit composed of a starter, a starter relay, a starter switch and a starter protection circuit.

2. The connection between the circuit diagram and the circuit. The diagram that uses the specified symbol to represent the circuit connection is called the circuit diagram. Correctly connecting the physical diagram according to the circuit diagram and drawing the circuit diagram according to the connection of the components in the physical diagram are the basic skills that must be practiced to learn electrical knowledge well.

3. Various electrical appliances and electronic control device parts in the automobile circuit make up the automobile circuit.The basic elements, familiarity with the structure and basic principles of various electrical appliances and electronic control devices are the basis for analyzing the circuit principles of electrical systems, understanding the connection relationship of circuits, and conducting circuit fault diagnosis.

4. Single-wire system, the two power supplies and all electrical equipment on the car are connected in parallel. The electrical equipment is connected to the positive pole of the power supply with only one wire, and the engine, body, frame and other metal bodies are used as common circuits to connect to the negative pole of the power supply. The single-wire system has the advantages of clear lines, few lines, convenient installation and maintenance.

5. The composition of the whole vehicle circuit The whole vehicle circuit is usually composed of power supply circuit, start circuit, ignition circuit, lighting and lighting signal device circuit, instrument information system circuit, auxiliary device circuit and electronic control system circuit.

sixIn order to prevent the circuit or component from burning the wire harness and electrical equipment due to iron or short circuit, various types of cars are equipped with safety devices. Some of these safety devices are connected in series in the component (or parts) circuit, and some are connected in series in the branch road. Understanding automotive circuits is an important skill in learning the basic knowledge of automotive circuits.
