STORAGE BATTERY CONTROL DEVICE, CHARGING STAND, AND STORAGE BATTERY CONTROL METHOD

摘要

The present invention controls the charging of an electric automobile or the like in a manner so that the impact on the power system is reduced even if electric automobiles or the like begin charging all at the same time. The present invention, which controls a power storage device mounted on the electric automobile or the like, applies a load current when storing power at the power storage device, calculates a voltage drop, and on the basis of the calculated voltage drop, limits the amount of charging of a storage battery mounted in the electric automobile or the like in a manner so that the voltage drop of the power system is less than a predetermined voltage drop. It becomes possible to reduce voltage fluctuations in the surroundings of electric automobiles or the like attempting to charge when many electric automobiles or the like begin charging at once.
