This report summarizes the work completed by Eneridge Inc. under the California Energy Commission (CEC) BESTFIT program for Agreement Number ZVI-21-002. Eneridge installed six battery-integrated direct current fast chargers (DCFCs), each rated at 150 kilowatts (kW), across three public sites in Southern California to demonstrate high-power charging with reduced grid impacts and minimized make-ready infrastructure requirements.
The project evaluated the operational performance of battery-integrated DC fast charging systems over a common 12-month period following commercial operation at all sites. Results showed that the chargers consistently delivered average peak charging power of approximately 89–104 kW per unit while limiting utility demand. At the Eastlake Village Center site, located in San Diego Gas & Electric (SDG&E) territory, measured demand remained within approximately 25–31 kW despite high-power charging, demonstrating effective demand charge mitigation through integrated battery buffering.
The project also identified operational considerations related to vendor continuity, following the charger manufacturer’s bankruptcy in mid-2024. Despite the loss of original equipment manufacturer support, Eneridge maintained charger operation through third-party maintenance providers. Overall, the project demonstrated the technical feasibility and practical benefits of battery-integrated DC fast charging systems while highlighting key considerations for future deployments.
