1. A method for an electric vehicle charging station to dynamically respond to power limit messages, the method comprising:
providing charging service to a first electric vehicle through a charging port of the electric vehicle charging station;
receiving a first message that indicates a first request to limit an amount of power to a first identified percentage;
based on a history of power provided through the charging port over a period of time, causing the amount of power that is capable of being provided through that charging port to be limited according to the first identified percentage;
terminating charging service to the first electric vehicle through the charging port;
providing charging service to a second electric vehicle through the charging port, wherein the amount of power that is capable of being provided through the charging port is initially limited to the first identified percentage;
receiving a second message that indicates a second request to limit the amount of power to a second identified percentage; and
based on the history of power provided through the charging port over the period of time, causing the amount of power that is capable of being provided through that charging port to be limited according to the second identified percentage, wherein the second identified percentage is applied to the amount of power being provided through the charging port prior to the amount of power being limited according to the first identified percentage.
