Abstract

An energy storage system includes an energy storage provided in a transportation unit, a connector electrically connectable to an external power transmission management apparatus, a power transmission circuit, and a processor. The processor is configured to control the power transmission circuit in accordance with an output from the external power transmission management apparatus to perform power transmission between the energy storage and an external power system, and control the power transmission circuit in accordance with an output from the external power transmission management apparatus, if a degree of variation in charging states in the energy storage and one or more external energy storages is greater than or equal to a threshold value, to perform power transmission between the energy storage and the one or more external energy storages to reduce the degree of variation before performing the power transmission between the energy storage and the external power system.
