Testing at Software Level - Key to Standards-compliant Charging Communication

The article explores the critical role of software testing in ensuring standards-compliant charging communication for electric vehicles. It delves into the challenges posed by incompatibilities in communication flows between vehicles and charging stations, which are a significant cause of disruptions in charging sessions. The author discusses the growing demand for proper charging infrastructure and the need for early detection of software bugs to minimize disruptions. The article highlights the complexity of charging modes and standards, particularly those defined by IEC 61851 and ISO 15118. It proposes open-source and black-box testing methods as effective solutions for ensuring compliance and interoperability. The author emphasizes the advantages of software-only testing, which can be implemented independently of hardware bottlenecks, and offers insights into the development of a testing framework that accommodates various add-ons. The article concludes with the importance of standards compliance for the success of e-mobility and provides an outlook on future developments in this field.
