Overview

Package ems implements energy management system routines for EEBus Overload Protection by EV Charging Current Curtailment (OPEV) use case.

The energy management system referred to as "Energy Guard" in EEBus protocol is responsible for following scenarios:

  • curtails changing current of connected electric vehicles to avoid overload of electrical installation

  • provide heartbeat mechanism to remote EEBus node (typically wallbox) to check its availability

  • sends error states to remote EEBus node (typically wallbox)
