Local Load Management (LLM) Settings
Local load management is the process of balancing the supply of electricity on the network with the
electrical load by adjusting or controlling the load of each EVSE in a local group which is based on
Gateway/Client architecture. The Gateway IC must be manually set the maximum current limitations so
that it will dynamically adjust output current in each Client IC by charging policy.
When LLM function is on, all EVSEs will request for charging to Gateway, and Gateway will calculate the
proper current limit and reply to each Client. Each EVSE will only allow charging when received a current
limit from Gateway. If disconnection occurred between a Client and Gateway, then the Client will use
fallback value as the limitation.
Local Load Management – Enable or disable Local Load Management function. This function can only be
enabled in a Gateway or Client EVSE.
