Useful, this can increase some kilometers.
The range extender may increase some mileage, but overall it is useful. The electricity stored in the range extender can allow the electric vehicle to go further when in use. This is equivalent to adding a small battery. The specific application effect is also related to the environment and weather conditions.
Type
Hydraulic generators can be made using hydraulic resources and hydraulic turbines using position differences, they can be made into generators turbine of different capacities and The principle of a hydroelectric generator is that water flows downward under the influence of earth's gravity. The energy from the water flow drives the turbine to produce electricity. However, the disadvantage is that if the difference in position is too low, the flow rate is too low. the speed is not fast enough, stable power cannot be provided. There is currently a way to generate electricity using ocean currents, but the generator is often damaged due to too strong ocean currents or excessive pressure under the sea surface.

Using coal, oil and other resources, combined with boilers and steam turbines, turbogenerators can be made. Most of these generators are high speed motors (3000 rpm).
Also, there are different types of generators that use wind energy, atomic energy, geothermal energy, tides and other energies.
In addition, due to the different current flow methods, they are divided into DC generators and AC generators. Large generators currently widely usedhave the alternators.
Compared to traditional fuel engines
The displacement of the engine equipped with the range extender is relatively small and its power is lower than that of the engine traditional when working the noise is also smaller and the work efficiency is higher.
In this way, in the structural design of the whole vehicle, the range extender consists only of the generator and the engine. The structure is simple, so it has high energy transmission efficiency, as well as high fuel consumption and fuel consumption. the emissions are relatively ideal. The range extender vehicle engine can also recycle energy from vehicle braking and driving downhill, thereby reducing energy loss.
Yes, but not necessary.
There will be losses during the energy conversion process.For example, if you use a generator to generate 100W of electricity, you might lose 150W of power from your battery, which isn't worth the gain.
If you use electricity, use the battery directly.
If you want to make a conversion, you can use an inverter, which can convert the 48 V electricity of an electric car into 220 V, or install a converter to convert the 48 V electricity into 12 V. No need to install a motor.
