E-mobility is an important part of the transition to renewable forms of energy, as electricity from eco-friendly renewable sources can be used to power vehicles. Optimum, cost-effective use of electric cars requires communication between different charge spots, the driver, and the vehicle’s battery system. As part of the Fraunhofer System Research for Electromobility project, Fraunhofer IIS is conducting research into communication technologies that integrate electric vehicles into their surrounding infrastructure.
With conductive charging, safety considerations dictate that communication is carried out for the most part through the charging cable. The future use of inductive charging systems in electric vehicles will require a reliable wireless communication interface for controlling and monitoring the charging process. This interface should ensure the unique wireless allocation of the vehicle to the charge spot and carry out the contactless transmission of simple control information to monitor the charging process or assist with optimum positioning of the vehicle. With its expertise in the field of wireless communication, Fraunhofer IIS is working on a solution based on inductive near field communication.
Communication infrastructure requirements for e-mobility:
- Recording usage and availability preferences of vehicle users
- Acquiring power grid specifications for optimum use of electrical energy
- Communication with smart grid
- Comparing usage preferences against power grid actual requirements
- Determining optimum charging strategy, which can be adapted as required
- Documenting power grid conditions and recording energy quantities
- Preparing data for billing process
