Power supply equipment and electrical equipment.
One, the power supply including batteries, generators, voltage regulators, the role is to supply the whole car electrical equipment power supply.
1, the main role of the battery is to start the engine when the engine does not work it to the whole car electrical equipment power supply.
2, the role of the generator when the generator is running at idle or above to replace the battery to all electrical equipment other than the starter power supply, and at the same time to the battery charging.
3, the voltage regulator is mainly in the engine speed and load changes, automatically maintain the output voltage of the generator to ensure safe operation.
Second, a wide variety of electrical equipment, different functions according to the function can be **** divided into ignition devices, starting devices, lighting and light signaling devices, instruments and auxiliary electrical devices and so on.
1, the role of the starter by the battery power supply, it will be transformed into a battery of electrical energy mechanical energy to drive the engine rotation, start the engine.
2, the ignition device in accordance with the engine working order to produce high voltage electricity, and through the spark plug, to ensure accurate ignition of the mixture in the cylinder.
3, lighting and light signaling devices to ensure that the car at night, rain, fog in the driving safety, the car is installed on all types of lighting tools. There are mainly front light, headlights, taillights, license plate lights and fog lights.
4, in order to ensure that the car's driving and parking safety can be installed in the car a variety of different signal lamps, meters were installed in the car to display the state of each part of the car parameters, such as engine water temperature, oil pressure. Remaining fuel, speed, etc.
5, auxiliary electrical devices, including windshield wipers, warm air, air conditioners and other aids.
Expanded information:
The first charging of the battery is called initial charging, which has a great effect on the battery's The initial charge has a great influence on the service life and charge capacity of the battery. If the charging is not enough, the battery charge capacity is not high, the service life is also short; if the charging is too much, the battery electrical performance is good, but it will also shorten its service life, so the new battery should be careful with the initial charging.
For dry charge lead batteries, according to the instruction manual, although in the two-year storage period if you need to use, as long as the density of the electrolyte added to the provisions of the shelves for 15min, do not need to charge can be put into use. However, if the storage period of more than two years, due to some oxidation on the plate, in order to improve its charge capacity, should be supplemented before use, charging 5h to 8h before use.
