Smart EV charging regulations requirements
Smart functionality
Charging points shall be equipped with:
- smart functionality to send and receive information;
- the ability to respond to signals to increase the rate or time at which electricity flows through the charging point;
- demand side response (DSR) services; and
- a user interface, e.g.: an app for charging.
Electricity supplier interoperability
Charging points must retain smart functionality, even if the owner of the charging point decides to switch their electricity supplier.
Off-peak charging
EV charging points must also incorporate pre-set, off-peak, and default charging hours whilst also allowing the owner to accept, remove or change these upon use. Default charging hours must be present to NOT charge during peak times of peak electricity use (8:00 -11:00 and 16:00 - 22:00 on weekdays). However, the charge point owner should be able to override this feature if necessary.
Randomised delayed charging
Charging points must also have a randomised delayed charging function of up to 10 minutes at the beginning of each charging session. This function protects the grid from destabilising during busy times when a number of charging points are being used at the same time. The application of randomised delayed charging ensures grid stability in a more manageable way for the network.
Continued charging
Charging points must rely on a communication network such as cellular, ethernet or Wi-Fi to send and receive signals to achieve smart functionality. Charging points must be able to continue charging electric vehicles - even if the charging point loses connection to the network.
Safety provisions
Charge points must be equipped with safety provisions to prevent the user from carrying out an operation that could risk their health and safety.
A measuring system
Charging points must have a measuring system in place to calculate the electricity imported and exported and the time the charging lasts. This information must be visible to the owner of the charging point.
Security
Charging points must be consistent with the existing cyber security standards ETSI EN 303 645.
