摘要： When it is determined by a determining portion (54) that the SOC of a first auxiliary power storage device (BB1) has reached a first lower limit value (TL), a switching control portion (56) generates a switching signal (SW) to switch from the first auxiliary power storage device (BB1) to the second auxiliary power storage device (BB2). A SOC estimating portion (52) measures the OCV for the first auxiliary power storage device (BB1), for which it has been determined that the SOC has reached the first lower limit value (TL) and has thus been disconnected, and estimates the SOC of that first auxiliary power storage device (BB1), based on that measured OCV. If the estimated SOC is higher than the first lower limit value (TL), after the SOC of the second auxiliary power storage device (BB2) has reached the first lower limit value (TL), the switching control portion (56) generates a switching signal (SW) to switch from the second auxiliary power storage device (BB2) to the first auxiliary storage device (BB1).

摘要： A battery state estimating unit (110) estimates an internal state of a secondary battery according to a battery model equation in every arithmetic cycle, and calculates an SOC based on a result of the estimation. A parameter characteristic map (120) stores a characteristic map based on a result of actual measurement performed in an initial state (in a new state) on a parameter diffusion coefficient (Ds) and a DC resistance (Ra) in the battery model equation. The parameter change rate estimating unit (130) estimates a DC resistance change rate (gr) represented by a ratio of a present DC resistance (Rc) with respect to a new-state parameter value (Ran) by parameter identification based on the battery model equation, using battery data (Tb, Vb and Ib) measured by sensors as well as the new-state parameter value (Ran) of the DC resistance corresponding to the p resent battery state and read from the parameter characteristic map (120).
