摘要： A power source system (5) includes a direct current power source (10), a direct current power source (20), and a power converter (50) having a plurality of switching elements (S1-S4) and reactors (L1, L2). The power converter (50) performs a direct current voltage conversion between the direct current power sources (10, 20) and a power source line (PL) in parallel by controlling the switching elements (S1-S4). Each of the switching elements (S1-S4) is disposed to be included in both a power conversion path formed between the direct current power source (10) and the power source line (PL), and a power conversion path formed between the direct current power source (20) and the power source line (PL). A phase difference (φ) between a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (10), and a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (20) is controlled according to the operation condition of the power converter (50).

摘要： A battery state estimating unit estimates an internal state of a secondary battery in accordance with a battery model equation in every arithmetic cycle, and estimates a charging rate and a battery current based on a result of the estimation. A parameter estimating unit obtains a battery current measured by a sensor as well as the charging rate and the battery current estimated by the battery state estimating unit. The parameter estimating unit estimates a capacity deterioration parameter such that a rate of change in difference (estimation error) between a summed value of an actual current and a summed value of an estimated current with respect to the charging rate is minimized. A result obtained by estimating the capacity deterioration parameter is reflected in the battery model by the battery state estimating unit.
