Electric Vehicle (EV) Charging Communication in the form of the Combined Charging System (CCS) is a core enabling technology for fast charging EVs as well as for future smart grid integration. Its interoperability is key for user acceptance and economies of scale, but at the same time a major technical challenge due to the huge number of different implementations, individual use cases and requirements on a diverse global market.
The CharIN Testival embraces this challenge and brings together companies from the Smart Charging community and their technology experts to conduct conformance & interoperability tests for electric vehicles and charging infrastructures or respective Electronic Control Units (ECUs) and Communication Controllers.
Rather than talking about interoperability, this is a hands-on event digging deep into implementing, supporting and testing interoperability. By participating at this event your company or organization benefits through unprecedented networking with international technology experts in smart charging communication.
The event takes place in different locations. Hosts are companies and institutions in the target area of CharIN. Partners can apply to host one of the next events.
