Automobile Power System Key working principle

The electrical power used in automotive electrical equipment is a DC power source, which comes from batteries or generators. The electrical system, which is connected by batteries, generators, regulators, charging status indicating devices, switches and wires, is called a power supply system (referred to as a power supply system).UCANDAS VDM2

The work of the automotive power systemThe battery and the generator in the MB SD Connect C4 power supply system are working in parallel. When the engine is in normal operation, the generator is powered by the generator and charged to the battery. At the time of starting, the battery supplies power to the starter. As the generator is driven by the engine through the drive rotation, when the engine speed changes, the generator output voltage will change. To meet the requirements of automotive electrical VAS5054A equipment and battery charging constant voltage, the power system are set within the voltage regulator to ensure that the generator output voltage stability in a certain range, to prevent the voltage fluctuation is too large and burn the electrical equipment. The charging state indicating means indicates the charge / discharge condition of the battery.

The layout of automotive power systems   VVDI2
At present, the power system on the car can be divided into 12V power system and 24V power system, and the general use of alternator and electronic regulator.Key Programmer
According to the electronic regulator installed in different ways, the power system layout can be divided into separate and integral two.key cutting machine
The distinctive features of the integral alternator power supply system are:
There is no longer a wire connection between the alternator and the voltage regulator. The system line is greatly simplified and the failure rate is greatly reduced. But the system failure can not quickly diagnose the failure of the car parts

In recent years, with the people riding comfort, fuel economy, environmental protection requirements of the increasing, new electrical installations in the car has been widely used, the proportion of automotive electronic accessories increased significantly, such as a variety of Electronic control system (electronic control jet, electronic control automatic transmission, electronic control suspension), cruise control, car computer network.Diatronik OBD Tool

Some electromagnetic or electric actuators have also gradually replaced the hydraulic drive and pneumatic actuator, which greatly increases the load on the electrical system, which requires the car's power system to provide higher power.
