The range extender has no effect on the battery.
More than 90% of the electricity generated by the range extender is supplied to the engine and less than 10% of the electricity is used to charge the battery. The range extender will not charge the battery when the range extender is charged. battery power is sufficient. The battery is only charged when the battery power is insufficient, so extending the range not only will not damage the battery, but also protects it in a sense.
The intelligent dual frequency range extender starts automatically or can be started manually when battery power is insufficient or under voltage. It will not overcharge the battery or prevent the battery from over-discharging. Battery protection actually extends the number of times the battery can be charged and discharged.
In extended-range electric vehicles, when the battery power is sufficient, the power battery drives the motor to meet the driving power requirements of the entire vehicle. At this point, the engine does not participate in the work. . When the battery power is consumed up to a certain level, the motor starts and the motor supplies power to the battery to charge the power battery.
When the battery is fully charged, the engine stops working and the battery drives the engine to drive the entire vehicle.
Detailed information:
1. It can operate in pure electric mode, requires small battery capacity, is inexpensive, and will not fail due to lack of power.
2. Operation in square recha modergeable is possible, which further improves the fuel economy rate based on hybrid power.
3. The battery charging power is low, so there is no need to build large charging facilities.
4. The battery can be charged and discharged shallowly, which is beneficial for battery life.
5. It has an external charging method and can use low-cost off-peak electricity at night to charge.
6. Simple structure, direct motor drive, easy maintenance and industrialization.
7. Energy saving: the engine is always in the best operating conditions, with high efficiency and low emissions.
8. Emission reduction: The overall fuel saving rate is high, and existing technology can save more than 50% fuel.

Ddifferent energy sources and different energy conversion processes.
1. Range-extended electric vehicles rely primarily on electric motors to provide power. The internal combustion engine does not directly drive the vehicle but serves as a generator to power the electric motor. The internal combustion engine of a hybrid vehicle can directly drive the vehicle or power the electric motor.
2. The internal combustion engine of an extended-range electric vehicle is only responsible for generating electricity, while the internal combustion engine of a hybrid vehicle can directly drive the vehicle or produce electricity under different operating conditions. work.
