An electric vehicle charge controller and charging method for controlling a charging rate for a battery of an electric vehicle is presented. The battery receives charge via a node connected to a power distribution source. The charge controller receiving a nodal voltage measurement for voltage at the node, receiving a value of electric power at the node, and determining a change in the electric power value based on a previous electric power value. When the change in electric power is greater than a load change threshold, the charge controller determines an estimate of voltage-to-load sensitivity. The charge controller determines the charging rate of the electric vehicle based on the nodal voltage, the determined voltage-to-load sensitivity, and a state of charge of the at least one battery, and controls the charging rate for the at least one battery in accordance with the determined charging rate.
