A system for charging a plurality of electric vehicles, the system comprising:

• a rail structure;
• a plurality of electric charging apparatuses disposed at respective vehicle charging stations;
• a first mobile base unit supported by the rail structure and configured to move along the rail structure between the respective vehicle charging stations, the first mobile base unit including a robot arm;
• a plurality of first batteries configured to provide power to the first mobile base unit to move along the rail structure;
• and
• a controller configured to:
• obtain a charge request from one or more electric vehicles;
• determine a charging sequence of the one or more electric vehicles based on vehicle parameters and charge parameters of the first batteries;
• move the first mobile base unit along the rail structure based on the charging sequence;
• and
• control the robot arm to move a charger of a corresponding electric charging apparatus from the corresponding electric charging apparatus to a corresponding electric vehicle located within the respective vehicle charging station associated with the respective electric charging apparatus such that the charger is electrically coupled to the corresponding electric vehicle.
