EV Power Management Controller
Controller that distributes available electrical power among EV charging points while considering site load, grid constraints, and local generation.
An EV power management controller coordinates charging load for multiple EVSE units or charging points.
It uses site-consumption measurements, configured connection limits, and current available power to modify charging current or power of individual devices.
The system may operate with local PV generation and direct surplus solar power to electric-vehicle charging.
Depending on the architecture, the controller communicates with energy meters, charging stations, EMS, OCPP systems, or a local control network.
Selection criteria include number of managed EVSE, response speed, available load-balancing algorithms, PV-surplus charging support, and communication interfaces.
Power-management and charging-load distribution controllers for groups of EVSE.
