1. A system for current control for regenerative charging, comprising:
one or more processors coupled with memory to:
facilitate, responsive to a first action by an actuator of an electric vehicle, a discharge of a battery of the electric vehicle;
identify, responsive to a second action by the actuator of the electric vehicle, a discharge capacity of the battery corresponding to the discharge associated with the first action by the actuator;
determine, responsive to the second action, a temperature measurement and a state of charge measurement of the battery;
determine, based on the temperature measurement, the state of charge measurement and the discharge capacity, a derate factor for charging the battery, wherein the derate factor is used to modify a current level supplied to the battery during charging of the battery from energy generated responsive to the second action; and
cause the battery to be charged according to the modified current level and the energy generated by the actuator.
