Embodiment 1

[0035] The new energy vehicle power conversion system includes a fuel power device, a power generation device, and an energy storage device. Both the fuel power device and the power generation device are connected to the vehicle running mechanism through a power separation device. The power generating devices are connected or separated by an automatic clutch device, and the power generating devices are used to provide power for the traveling mechanism of the vehicle and provide electric energy for the energy storage device.

[0036] As the main drive structure, the fuel power unit and the power generation unit can realize the mixed use of gasoline and electricity, and control the operation sequence to realize pure electric drive or oil drive or hybrid electric drive. Multiple driving modes can effectively increase the power demand of the car and battery life requirements.

[0037] In any of the above schemes, preferably, the vehicle running mechanism comprises a vehicle front ...

Embodiment 2

[0047] Compared with embodiment 1, the improvements are:

[0048] In any of the above schemes, preferably, the new energy vehicle power conversion system further includes a multi-effect solar power generation device 18 .

[0049] The storage battery pack 7 is connected with the multi-effect solar power generation device 18 through wires.

[0050] At the same time, the multi-effect solar power generation device 18 provided with the power generation of the engine 4 can effectively improve the power generation capacity of the entire system, and further improve the continuous battery life.
