CHARGING AND DISCHARGING CONTROL DEVICE, CHARGING AND DISCHARGING CONTROL SYSTEM, CHARGING AND DISCHARGING CONTROL METHOD, AND PROGRAM

摘要

Within the range of a secondary limit current (±I_adj_max) set based on the performance of a secondary battery (140), a charging and discharging control device (170) determines an upper limit value (I_adj_limit) or a lower limit value (-I_adj_limit) of an SOC adjustment current (I_adj) in accordance with the load power (demand power and regeneration power) of a vehicle (100). Using an adjustment logic set based on these limit values of the SOC adjustment current (I_adj), the charging and discharging control device (170) also determines the SOC adjustment current (I_adj) corresponding to the measured SOC value of the secondary battery (140).
