An appropriate charging infrastructure is critical to support the rapidly growing electric vehicles market worldwide. Hence, Infineon has joined the global Charging Interface Initiative e.V. (CharIN). CharIN’s goal is to develop, establish and promote a world standard for a charging system for all kinds of battery-powered electric vehicles. Among its founding members are major automotive manufacturers.

Infineon aims to provide CharIN its system expertise in electric mobility as well as its automotive safety and data security knowledge.

For a broad adoption of electric cars, a reduction of costs is crucial, particularly with regard to batteries, as well as an increase in travel range. In addition, a smart grid and an adequate charging stations infrastructure with standardised connectors and communication interfaces are essential.

Within the energy sphere, Infineon’s products play a central role in three aspects: in generating energy from the wind and sun, in transmitting energy and in feeding energy into batteries and feeding energy from the electric vehicle back into the grid. Infineon’s security know-how supports secured payment procedures at charging stations and when excess energy of parked electric vehicles is fed back into the grid to make up for peak demand of other consumers. Charging stations could also be equipped with additional semiconductors for a two-way exchange of electric energy. These procedures would be billed through the electricity provider. To this end security chips are needed for authentication and secured data exchange at the communication interfaces of charging station and vehicle.
