Abstract
A power transmission management apparatus includes a first connector electrically connectable to energy storages respectively provided in transportation units, a second connector electrically connectable to an external power system. A processor is configured to obtain charge state information, obtain power system request information to be input to or output from the external power system, control power transmission between the first connector and the second connector according to the power system request information, determine whether a degree of variation in the charging states in the energy storages is greater than or equal to a threshold value, and control power transmission between at least two among the energy storages to reduce the degree of variation before controlling the power transmission between the first connector and the second connector according to the power system request information if the degree of variation is determined to be greater than or equal to the threshold value.
