How important do you expect the following barriers for implementing EV to be in 2020? And ditto for 2030 and 2050.

The implementation of millions or even hundreds of millions of electric vehicles (EVs) will require a lot of effort on technical and financial aspects, but also on socio-economic aspects.

The main bottleneck for the electric car is the price of the battery system. Today, the price of a total battery system for electric cars can go as high as € 20.000. This should be reduced in order to achieve mass demand. There are also still developments needed in charging time (now: ~6 hr, fast charging 15 minutes) and energy density in order to be able to drive longer distances (now ~200 km.).
