What does the car power supply system include?
Battery: It is an indispensable part of a car. It can be divided into traditional lead-acid batteries and maintenance-free batteries. Because the battery uses lead-calcium alloy as the grid frame, the amount of water decomposition and water evaporation generated during charging is small. In addition, the shell adopts a sealed structure, which releases less sulfuric acid gas. Therefore, compared with the traditional battery, it has the advantages of no need to add any liquid and long storage time of the terminal pile head.
Automobile generator: it is the main power source of the automobile. Its function is to supply power to all electrical equipment (except starter) and charge the battery when the engine is running normally (above idle speed). Based on the three-phase stator winding of ordinary alternator, a set of three-phase bridge rectifier is added by increasing the number of winding turns and leading-out joints. At low speed, the primary winding and additional winding are output in series, and at high speed, only the primary three-phase winding is output.
Voltage regulator: Because the generator is driven by the automobile engine, and the speed of the engine is not constant, the output voltage of the generator will be unstable. Therefore, it is necessary to have an electronic device to control the generator, so that the generator can output stable voltage at different speeds of the automobile engine.
