When: Phase 1A – June 2022
To protect the stability of the national electricity system from high volumes of devices switching on or off at the exact same time, a Randomised Delay of up to 1800 seconds (30 minutes) is required when charging starts or stops – except for where the user has overridden this or when the charger is responding to a DSR signal.
It must also be possible to increase or decrease the maximum random delay remotely.
ev.energy is able to simplify this requirement for charger manufacturers by implementing all the necessary randomised delays at the platform level, through the use of OCPP charge schedules. We are also working with the industry on an advanced controlled ramp rate solution as part of the future Phase 2 regulations.
