Development of a Safe Charging Infrastructure System: Requirements, Design, Verification and Validation

With the ongoing shift from fossil fuels towards electric mobility, there’s an increasing need for charging infrastructure for electric vehicles, both private and public. With this increasing role of charging infrastructure in day to-day life, safety and security should be guaranteed for these systems. In this work we report on the development of an integrated electronic charging infrastructure system. The development was based on both current functional safety and charging infrastructure standards. The whole development process is presented, including requirements analysis, overall system design, safety hardware and software design, as well as the verification & validation of the safety system against the requirements set in the beginning. The presented work can be used as a basis and reference for the functional safety aspects when developing next generation charging infrastructure systems.
