Description

E-Mobility is one option for a Smart Grid in respect to the integration of energy storage and therefore the integration of renewable energies. Furthermore it would serve the conservation of individual mobility in times of decreasing fossil fuel supply. The full scope of its capability, however, can only be achieved by seamless integration into a Smart Grid architecture. E-Mobility provides a large, flexible load and storage capacity for the Smart Grid. This however depends on the use case, some of which are not capable of contributing to these advantages. Basic charging (charging the car at a plug existing today) does not offer the full scope of possibilities from a Smart Grid perspective.

A seamless integration can be provided through bidirectional power flow, utilization of manageable loads and necessary information exchange between onboard and grid automation, including price information.

E-Mobility will serve the following functions:
·     
a primary,secondary, tertiary reserve;
·     
a manageable load;
·     
power system stabilization;
·     
power quality;
·     
load levelling;
·     
load shedding;
·     
individual mobility (not relevant for Smart Grid);
·     
energy conservation (increased efficiency compared to combustion engines) under the constraint of fulfilling environmental constraints.

Total electrification of the vehicle will furthermore promote the role of IEC standards in the vehicle domain. This has to urgently be dealt with, however it is not within the scope of a Smart Grid discussion.
