POWER SOURCE CONTROL DEVICE AND POWER SOURCE SYSTEM

WIPO Patent Application WO/2018/008567

A1

A power source system that comprises: a plurality of power storage means (12, 13); and a switching unit that includes a plurality of switch means (21-25) that are provided on electrical paths that run to the power storage means and that switches the power storage means between a parallel state and a series state. The power storage means include: a first power storage means (12) that has a positive electrode side that, in the series state, is connected to a low-voltage load (14); and a second power storage means (13) that has a positive electrode side that, in the series state, is connected to high-voltage loads (15, 16). A power source control device (30) that comprises: a capacity acquisition unit that acquires the remaining electrical capacity of the plurality of power storage means; and a current control unit that, in the parallel state, on the basis of the remaining electrical capacity acquired for each of the power storage means by the capacity acquisition unit, adjusts the resistance values of variable resistance parts that are on the electrical paths that run to the power storage means and thereby controls the charging/discharging current of each of the power storage means such that the difference between the remaining electrical capacity of the first power storage means and the remaining electrical capacity of the second power storage means is a desired amount.
