Vehicle Interoperability Testing Symposium VOLTS

A special interoperability testing event in California, granted by the California Energy Commission (CEC), took place in the second week of May in Port of Longbeach, hosted by WattEV.

The VOLTS Testing Symposium hosted over 400 attendees to observe industry experts actively testing ISO 15118 and its features through a series of public demonstrations. There were 4 school buses, 4 trucks, 13 electric cars, 18 charging stations, and 7 test systems. For the first time ever, results of this testing is publicly-available.

Now available: The first of its kind, public interoperability testing data collected at VOLTS 2023.

This report contains:

  • Almost 400 hours of interoperability testing data which took place over the course of 2 days, across 7 test slots, and 174 EV-EVSE 2 hour pairings.
  • Summarization of over 1,000 individual tests where more than 50% of all tests used ISO 15118 communication.
  • Critical next steps to support an interoperable EV charging ecosystem.
VOLTS represented a key platform to enable end-to-end-testing which is a prerequisite for a seamless customer journey and thus significantly contributes to accelerating the market ramp-up of electromobility.
