Abstract:
A power exchange controller adjusts a power exchange between a plurality of batteries and an upper authority to control deterioration of a state-of-health of each of the plurality of batteries at an equivalent rate. The power exchange controller is operable to receive a total power demand from the upper authority and each of the plurality of batteries connected to a charging station and adjust the power exchange between the upper authority and each of the plurality of batteries by detecting a battery temperature of each of the plurality of batteries and determining the power exchange with each of the plurality of batteries based on the total power demand and an equalized temperature determined from each battery temperature. Each power exchange is determined so that the battery temperature of each of the plurality of batteries during the power exchange is adjusted to the equalized temperature.
