The working principles of range-extended electric vehicles are as follows:
1. External charging mode, which charges the battery while the car is parked;
Second, in pure electric mode, when the electric vehicle's battery is fully charged, the battery provides power to the electric motor to drive the wheels.
Third, in range-extended operating mode, when the battery power is insufficient, the engine generates electricity to charge the battery or directly supplies the electric motor to drive the wheels.
The reason why EV Resources Network believes that range-extended electric vehicles should be given more attention is because they have the following major advantages:
First, it has low fuel consumption because the engine is only responsible for charging, so only a small displacement engine is needed to complete the work.
Second, the range is guaranteed. After the battery is depleted, the range extender becomes a generator to provide power to the electric motor, which effectively solves the range anxiety problem that is of great concern to everyone.
Third, it has extremely low noise. Because the range extender has a very small displacement, it produces very low noise when it is working.
Fourth, range-extended electric vehicles (REEVs) are relatively less technically challenging than pure electric vehicles because both are purely "electrically driven." The engine in a REEV does not need to intervene in the drive system, so there is no need to consider complex mode switching.
