Randomised Delay

What is Randomised Delay?

• Charge points come equipped with a feature that introduces a random delay of up to 10 minutes at the start of a charging session. This prevents surges in demand and reduces strain on the national grid, especially when multiple chargers activate at the beginning of an off-peak period.
• As per new regulations, a charge point must:
  • Be capable of operating with a random delay of up to 1800 seconds.
  • Operate with a random delay of up to 600 seconds (10 minutes) by default, adjustable to the nearest second.
  • Allow for remote adjustment of the maximum delay duration via a communications network.
  • Permit the owner to override the random delay at any time.
• The random delay will not be applied if:
  • The owner or an end-user has overridden it.
  • An equivalent random delay has already been applied.
  • The charge point is providing demand-side response (DSR) services at that time.
• The "relevant time" refers to when electricity would start flowing through the charge point or when the flow rate would change, if not for the delay.

What Does This Mean for EV Users?

• EV users who have added a charger should have the ability to modify the random delay configuration to suit their needs.
