Derivation of Basic Energy Storage Parameters for Future Electric Vehicles

For the engineering of ecologic vehicles the search for adequate energy storage types is currently in the focus. The question for future energy storage technologies is whether they are able to successfully compete against conventional vehicular energy storages like fuel and gas tanks. In the paper a methodology is presented that enables an estimation of required energy storage characteristics for future storage technologies that can be compared to conventional ones. Several showcase calculations are done for a multitude of existing vehicles to get a basis of comparison. As a result necessary energy storage values like energy density and power density are presented and compared to conventional vehicular storage types.
