Location power monitoring and charge distribution using intelligent electric vehicle supply equipment

摘要

Embodiments include an intelligent electric vehicle supply equipment (EVSE) unit. The intelligent EVSE unit includes a communication port to receive an active power load value and a maximum installed power load value from an external power meter. The intelligent EVSE unit includes a buffer-reduced maximum installed power logic section to receive a safety buffer value, to receive the maximum installed power load value from the communication port, and to generate a buffer-reduced maximum installed power value dependent on the safety buffer value and the maximum installed power load value. The intelligent EVSE unit includes a real-time power availability logic section to generate an available power value dependent on the buffer-reduced maximum installed power value and the active power load value. The intelligent EVSE unit includes a power regulator to control an amount of power made available to charge one or more electric vehicles dependent on the available power value.
