An electric charging system for an energy storage system, comprising: a charging station electrically coupled to the energy storage system, said charging station transferring charging energy to the energy storage system at a maximum fast charge rate in a first operational mode and transferring charging energy to the energy storage system at a slower charge rate in a second operational mode, said modes responsive to a control signal; a data collection system acquiring a set of data indicating a state of charge of the energy storage system and one or more desired charge optimization parameters; and a station control, responsive to said set of data and to said desired charge optimization parameters, automatically establishing a first charging profile for the energy storage system, with said first charging profile asserting said control signal and operating said charging station in said second operational mode whenever said charging station is able to transfer sufficient energy to the energy storage system at said slower charge rate to meet a charge target, said first charging profile asserting said control signal to operate said charging station in said first operational mode whenever said charging station is unable to transfer sufficient energy to the energy storage system at said slower charge rate to meet said charge target, characterized in that said station control, responsive to said set of data, detects a change to said charge target and establishes a second charging profile after an initiation of energy transfer to the energy storage system responsive to said first charging profile wherein said station control dynamically alters energy transfer to implement said second charging profile to meet said change to said charge target. a charging station electrically coupled to the energy storage system, said charging station transferring charging energy to the energy storage system at a maximum fast charge rate in a first operational mode and transferring charging energy to the energy storage system at a slower charge rate in a second operational mode, said modes responsive to a control signal; a data collection system acquiring a set of data indicating a state of charge of the energy storage system and one or more desired charge optimization parameters; and a station control, responsive to said set of data and to said desired charge optimization parameters, automatically establishing a first charging profile for the energy storage system, with said first charging profile asserting said control signal and operating said charging station in said second operational mode whenever said charging station is able to transfer sufficient energy to the energy storage system at said slower charge rate to meet a charge target, said first charging profile asserting said control signal to operate said charging station in said first operational mode whenever said charging station is unable to transfer sufficient energy to the energy storage system at said slower charge rate to meet said charge target, characterized in that said station control, responsive to said set of data, detects a change to said charge target and establishes a second charging profile after an initiation of energy transfer to the energy storage system responsive to said first charging profile wherein said station control dynamically alters energy transfer to implement said second charging profile to meet said change to said charge target.
