From here we can see that the root cause of generator generation is the rotating magnetic field generated by the high-speed rotation of the rotor. Without this rotating magnetic field, it would be impossible to generate electrical energy. And the energized conductor in the magnetic field movement will be affected by the force, so the generator rotor operation will be a lot of resistance. This resistance acts on the crankshaft of the engine and blocks the operation of the engine. Therefore, the generator is also to consume the engine power, from the most fundamental factors, the electric energy on the car is converted from fuel, so the power consumption is the consumption of oil, the generator is equivalent to a tool to convert the chemical energy of fuel into electric energy, the higher the power generation, the more natural fuel consumption. Generally speaking, the power of the generator is between 0.8 and 1.5 kilowatts, which is enough to meet the electric energy consumption of all the electric appliances in the car working at the same time, and there will be energy left over to charge the battery. If the generator is not producing enough electricity under certain special circumstances, the battery will help to provide power.
