Information
Definition
Load management controls EV charging demand in response to available electrical capacity, site load, user priority or grid constraints. It is normally assessed against site capacity, maximum demand, charger grouping and the behaviour expected when electrical demand changes.
Why it matters
It enables more chargers to be installed without oversizing the electrical supply and helps avoid overloads or costly upgrades. For UK users, it affects whether EV charging can be added without unnecessary supply upgrades or nuisance limitation of other site loads.

ENA EREC G100 is the UK Engineering Recommendation for customer export and import limitation schemes used to control power flow at a grid connection point. In EV charging it is relevant to load management, constrained connections, V2G export control and maximum import limitation.
Electric Vehicles (Smart Charge Points) Regulations 2021
The Electric Vehicles (Smart Charge Points) Regulations 2021 set Great Britain requirements for private smart charge points, including smart functionality, security, default charging behaviour and randomised delay. They apply to relevant charge points sold for domestic and certain private use cases.
