The engine drive of extended range new energy vehicles mainly involves specific links in their working mode. The following are direct output answers in formats 1, 2, and 3:
1. The engine does not directly drive the wheels: In extended range new energy vehicles, the main function of the engine is not to directly drive the wheels. On the contrary, it is usually used as a generator to charge the battery pack.
2. The engine charges the battery: When the battery is low, the engine will start and run, converting fuel into electrical energy through a generator to charge the battery pack. This process is the key to extending the driving range of range extender cars.
3. The engine indirectly supports vehicle operation: Although the engine does not directly drive the wheels, it indirectly supports the vehicle's electric drive system by charging the battery. When the battery is fully charged, the electric motor will drive the wheels to drive the vehicle. When the battery is low, the engine starts and charges to ensure that the vehicle can continue to drive.
The engine of an extended range new energy vehicle mainly drives the generator to charge the battery, indirectly supporting the vehicle's electric drive system.
