摘要： A rechargeable battery is used with a plurality of battery cells restrained by a restraint member. After the rechargeable battery has the restraint member removed therefrom and is thus disassembled when the rechargeable battery is subsequently re-restrained by the restraint member and thus reused an internal resistance measurement unit measures the rechargeable battery's internal resistance based on battery data detected after the rechargeable battery is re-restrained. At least for the internal voltage, from a value thereof as measured after the battery is re-restrained an evaluation unit evaluates a value of the rechargeable battery that is reused.

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).

摘要： [Summary][Objective] Estimation accuracy in a battery status estimating device which estimates a charge status of a secondary battery should be improved further more.[Means for Solution] In an SOC estimation by integration of a charge-and-discharge current, influence of a sensor error cannot be disregarded, and the influence of such an error is accumulated as time passes. On the other hand, in an SOC estimation based on measured values of a battery voltage and a battery temperature, estimation accuracy largely depends on a load-generation pattern. Then, in accordance with the present invention, by mixing both, while one of them is reset based on a reliability in accordance with an operation situation and/or an input current value which will be the premise for an SOC estimate calculation in a battery model is set up based on the reliability, it becomes possible to compute an SOC estimate in high accuracy as much as possible in accordance with the operation situation.

摘要： A hybrid vehicle (1) includes a battery (10-1), a motor-generator (32-2) operable to produce driving force using electric power of the battery (10-1), a charger (28) operable to charge the battery (10-1) by means of an external power supply, and an ECU (40). The ECU (40) stores a given parameter used in battery model expressions. The parameter varies according to the status of the battery (10-1). During running of the hybrid vehicle (1) and during charging of the battery (10-1) with the external power supply, the ECU (40) collects data related to the status of the battery (10-1), corrects the parameter based on the data, and calculates a value of charging rate (SOC) of the battery (10-1). The ECU (40) controls charge/discharge of the battery (10-1), based on the calculated SOC value.

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 secondary battery is implemented as an assembly of a plurality of battery modules. An ECU calculates a deterioration indicator quantitatively indicating a degree of deterioration of a battery module for each of the plurality of battery modules, and detects as a module to be replaced, a battery module of which deterioration indicator has reached a prescribed replacement level. The ECU further extracts a module to additionally be replaced, which should be replaced simultaneously with the module to be replaced above, from battery modules of which deterioration indicator has not reached the replacement level, among the plurality of battery modules.
