Technical Field

The range extender uses an internal combustion engine as a power source to drive a direct current generator to perform direct current power generation, and the power source comprises: the high-efficiency areas of the generators such as the fuel engine, the gas engine, the M100 methanol engine and the like are matched with the minimum oil consumption area of the power source.

A generator is a device that converts kinetic energy or other forms of energy into electrical energy. The general generator converts the energy stored in various primary energy sources into mechanical energy through a prime motor, then converts the mechanical energy into electric energy through a generator, and sends the electric energy to various power utilization places through a power transmission and distribution network. The generator is the inverse of the motor basic principle. The motor is a device which converts electric energy into work by using the principle of current magnetic effect. The generator utilizes various power (such as water power and wind power) to enable the coil to rotate between two poles of the magnet; when the coil rotates, the magnetic field in the coil changes, so that induction current is generated, and the device converts the function of power into electricity by applying the principle of 'electromagnetic induction'.
