1. A conventional front-wheel driven car may be combined with an electric rear-wheel drive. The connection between the two is electrically controlled. It is called an electric .

2. Despite the front motor with rear wheel drive, an additional motor is still possible, which can supported the combustion engine.

3. The electric motor then often takes the place of the .

4. All combinations of combustion engine with electric motor can be referred as hybrids.

5. can be used on the go due to a lack of power, a pure electric car can only be returned very slowly to a roadworthy situation.

6. With a Range Extender you have to calculate a comparatively high .

7. There are hybrid drives, where the capacity of the high-voltage battery is so low that only a little bit more than kWh (number) can be used.

8. One could summarise the work of James Atkinson in this way: He tried to extend only the (picture above).

17 For a liquid battery or the flow cell technology you need (no number) tanks.

18. So that is essentially than recharging the battery .

19. A sufficient battery equipment for heavy-duty long-distance transport not only has the disadvantage of high weight, but also problems with timely .

20. It will take quite some time until sufficient will be produced in Germany as well.
