Automotive alternator based on self-diagnosis function

Abstract

The invention relates to the technical field of automobile generators, specifically to an automotive alternator based on a self-diagnosis function. The automotive alternator comprises a light emittingdiode, the positive electrode of which is connected with the L end of a regulator and the negative electrode of which is connected with the B + output end of a generator. When the light emitting diode is out, there is no voltage difference between the B + output end of the generator and the L end of the regulator, and the generator generates electricity normally; when the light emitting diode lights up, there is voltage difference between the B + output end of the generator and the L end of the regulator, and the generator generates electricity abnormally. According to the invention, whetherthe generator works normally to generate electricity by connecting a light emitting diode in series at the B + output end of the generator and the L end of the regulator, and whether automobile faultscome from an AC generator or other places can be judged by checking the on-off condition of the light emitting diode; and through a fault display lamp, users can conveniently find out the fault causeof the generator.

Description

technical field [0001] The invention relates to the technical field of automobile alternators, in particular to an automobile alternator based on a self-diagnostic function. Background technique [0002] With the improvement of people's living standards, people's car ownership is also increasing day by day. And people's requirements for the comfort of automobiles are constantly increasing, and the noise of automobile generators has also aroused widespread concern. [0003] Automobile alternator is a device that converts mechanical energy into electrical energy. It is an important power source in automobiles and provides electricity for electrical equipment on automobiles and normal driving of automobiles. During the use of automobile alternators, sometimes there will be faults such as no power generation, low output voltage, and high output voltage. For these faults, some are not easy to judge, and they can only be found and repaired by elimination method, which is ineffici...

AI Technical Summary

Problems solved by technology

During the use of automobile alternators, sometimes there will be faults such as no power generation, low output voltage, and high output voltage. For these faults, some are not easy to judge, and they can only be searched and repaired by troubleshooting, which is inefficient and easy to damage the motor.

And in most cases, the car cannot start normally, and it is impossible to judge whether it is a generator failure or a severe battery loss.
