A distributed energy management method and system 100 are disclosed for managing a charge rate of an array of EVSEs 140 that share a common power source. In the disclosed method and system, control of the power sharing is distributed at the individual EVSE level. For example, each EVSE includes a communication device 540 and a controller 530. The communication device is used to receive a signal relating to a present current capacity utilization of the shared circuit, such as an indication of availability or unavailability of current capacity on the shared circuit. The controller is configured to generate a variable update interval, and initiate adjustment of the charge rate of the EVSE according to the variable update interval based on the present current capacity utilization as indicated by the received signal.
