摘要： An electric storage system includes electric storage blocks and a controller determining the state of each of the electric storage blocks. The plurality of electric storage blocks are connected in series, and each of the electric storage blocks has a plurality of electric storage elements connected in parallel. Each of the electric storage elements has a current breaker breaking a current path within the electric storage element. The controller acquires at least one parameter of an internal resistance and a full charge capacity of each of the electric storage blocks, and uses a change rate between the acquired parameter and a reference value to specify the number of current breakers in a broken state (the number of breaks) in each of the electric storage blocks. The reference value refers to the value of the parameter in the electric storage block not including the current breaker in the broken state.

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： 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).
