Electric vehicles (EVs) are zooming into our lives, but charging compatibility can be a bumpy ride. Enter the CharIN Testival, where EVs and chargers get paired up like cars at a high-tech matchmaking event. At the recent Cleveland Testival, over 300 industry players from Ford to Tesla tested their equipment in real-world scenarios, uncovering glitches and hidden kinks before they frustrate drivers.
This “speed dating” approach simulates everyday charging situations. Imagine struggling with “smart” charging, bi-directional power transfer, or confusing error messages. The Testival lets engineers witness these frustrations firsthand, identifying incompatibility before products hit the market.

The event’s impact? Claas Bracklo, CharIN’s Chair, puts it bluntly: “Bridging interoperability gaps is critical to ensure the electric vehicle market’s growth.” With billions invested in charging infrastructure, seamless compatibility is key to a smooth EV journey.
Highlights:
- Record-breaking event: Over 300 participants from 17 automakers and 18 EV charging providers, making it the largest Testival in North America.
- Real-world testing: From “smart” charging to security protocols, the event replicates everyday driver experiences to uncover potential issues.
- Exclusive testing: The Testival featured the proposed SAE J3400™ standard, ChargeX error codes, and new cybersecurity protocols.
- Plug & Charge progress: Participants tested the implementation of Plug & Charge with multiple PKI roots, paving the way for a more seamless charging experience.
Next stops: The Testival travels the globe! Head to Arnhem, Netherlands (January) or Ansan-si, Korea (April) to see the future of EV charging compatibility unfold.
