e-mobility - The key to success

The limitations of electric vehicles are (1) the in comparison to combustion engine lower energy desity and the therefore lower range of the vehicle. In addition (2) the missing charging infrastructure which should be provided on every area where the vehicle "naturally" parks for longer periods of time. (e.g. at home, at work, at public areas, at supermarkets, ...)

The energy storage

The further development and distribution of the lithium-ion technology and its significantly higher energy density enabled the breakthrough. Due to safe materials (seperators as ceramics) and new chemical compositions (e.g. LiFePO4) leades to higher thermical stability and reduces the danger of fire ("thermal runaway") significally. Still, the development of the battery technology hasn't reached a final stage. The newest developments (lithium-air) even will enable us in the future to higher energy desities than gasoline.

All energy storage systems have in common that the good working single battery cells can take damage when they are used in a high number battery pack. The intelligent control of the battery cells is as important as the chemical composition of the cell itself.

The charging infrastructure

The main factor of success for any type of mobility is an already available infrastructure, which is adjusted to its needs. In terms of electric vehicles, charging stations must be available on every parking area and a local integration in the power grid must be enabled. Besides an intelligent communication between the charging stations, power grid, vehicle and driver, the charging station should provide flexible and "aceptable" charging times. (e.g. fast charging of 100km in a coffee break)
