The performance of the electric vehicle converter is broken: the car can walk normally, but the horn and the light are all invalid. In the end, there is a problem with the circuit of the converter or the input and output of the converter, so that the components powered by the converter will not be Work, including headlights, horns, turn signals, etc. Because the converter converts the high-voltage power supply of the electric vehicle into a low-voltage power supply suitable for parts such as headlights, the output is generally 12V, and the horn and the light are all driven by 12V.
What is a converter?Converter aka: DC buck transformer, etc.
Is the voltage of the electric vehicle such as 48-60-72-84-96-108-120V DC voltage converter 12V DC voltage AC means AC DC means DC
Because cars and motorcycles appear earlier than electric vehicles, their lighting and other power supplies are standard 12V power supply. If you want to share a gas horn such as a xenon lamp, you need to reconnect the high voltage converter 12V. Without DC converters, they use relatively high-voltage electricity to supply power. The advantage is that it saves costs, the disadvantage is broken, and it is relatively difficult to find alternatives.
Why do electric vehicles have converters?Generally, the electric motor is equipped with a DC-DC converter, that is, the battery voltage is turned to 12V, and thus the 12V voltage is used for power supply of the vehicle electric appliance except the controller, such as a headlight, a flash circuit, a speaker and a controller high brake signal. Electricity equality! Of course, electric bikes generally do not have this converter. It can be directly powered by the battery voltage, but: 1 large converter electric car is generally available, because his headlights, speakers, meters, these power supply requirements are relatively small, the electricity is much more complicated, if directly powered by battery, safety hazards To be up; it is much safer to use 12V.
2. Horns, forks, headlights, these large voltage accessories are relatively small, if you use these 12V accessories, because the existence of motorcycles, everywhere. It is much more convenient to use 12V to supply power.
The converter has three line negatives (black), positive (red) is the input, and yellow (output). First, use the universal meter to check that the black line and the red line master have voltage. The voltage standard is the voltage after the battery is connected in series. If there is input, check the output voltage of the black line and the yellow line. If there is no voltage or voltage, If it is low, it can be concluded that the converter is bad, and if there is a normal voltage of 12V, then it is good.
