What is the Voltage of a Car Generator?
1 Answers
The normal voltage range of a car generator after starting the engine is "15.3V-12.8V"; below is relevant information about car generator voltage:1. Normal generator voltage conditions: When the vehicle's air conditioning is operating and other electrical devices are used excessively, the generator voltage may drop below 12.8V. At this point, the vehicle draws current from the battery and cannot charge the battery. After starting, the battery voltage is essentially equal to the generator voltage, minus the voltage drop due to line loss from the generator to the battery. When the engine is not running, the normal battery voltage range is 13.8V-12.8V. 2. Introduction to the generator: The car generator is the main power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) while the engine is running normally (above idle speed) and simultaneously charge the battery. Based on the three-phase stator winding of a standard alternator, additional winding turns are added with lead-out terminals, and an additional three-phase bridge rectifier is included. At low speeds, the output is from the series connection of the original and additional windings, while at higher speeds, only the original three-phase winding provides the output.
