1930s ,the first fuel cell electric vehicle
In 1990,THE FIRST HYBYID CAR!!!
An example of hybrid drive system
Lithium power capacity (electric motor)
Mix their energy,so we can get hybrid energy
1) Immature technology.
2) High cost.
3) Difficult to supply energy.
1) More environmental.
2) More slient.
3) Energy conservation.
Nowadays & Future
With the technology and science improving, our technology production will be more advanced and environmental. So let us do it now ! ! !
