define a plurality of discharge categories, including a transportation category, a transfer category and a reserve energy category;

proportion respective battery power in the electric vehicles by setting a respective percentage allocation for the plurality of discharge categories;

signal the electric vehicles to respectively charge when at least one of the plurality of discharge categories falls below the respective percentage allocation;

match the electric vehicles with a driverless status to respective target charging stations and request energy transfer from the electric vehicles with a driver-operated status to the electric vehicles with the driverless status when the respective target charging stations are not available;

group the electric vehicles in respective virtual boxes based in part on respective physical locations of the electric vehicles and determine whether a respective total battery charge level is greater than a respective total power demand in the respective virtual boxes, the respective virtual boxes including a first virtual box and a second virtual box adjacent to the first virtual box; and

control operation of the electric vehicle, including directing energy transfer to at least one of the electric vehicles in the first virtual box from one or more of the electric vehicles in the second virtual box when the respective total power demand in the first virtual box exceeds the respective total battery charge level in the first virtual box.
