Connecting EV chargers and the EMS

Research question

How can different charging equipment enter a shared energy-management workflow? Beyond OCPP support, integration depends on available information, supported commands, measurement locations and the relationship between charging service and energy constraints.

Research leadership and approach

Luo leads equipment and energy-information integration. Separate publications address a smart distribution panel for non-OCPP chargers and an OCPP-compliant PV–storage charging proof of concept. The laboratory also developed charging operations and payment using existing LINE Pay accounts. These research and service functions have distinct scopes and do not imply site-wide automatic control.

Implemented work and scope

Hardware implementation, integration publications and charging-service workflows form the research basis. The shared EMS currently provides unified monitoring and manual operation. Automatic dispatch would require equipment-specific verification of commands, protection conditions and control permissions. Charging availability does not imply implemented bidirectional V2G discharge.

A proposed collaborative study

A proposed study models controllable loads and service constraints across heterogeneous chargers. Begin with a monitoring/control capability matrix, then use de-identified charging events, if available, to characterize arrivals, departures, energy and service requirements. Compare rule-based and optimized scheduling. Outputs could include interface specifications, reproducible scenarios and method comparisons; field control tests require a separate plan.
