    摘要: A first calculating section (118) calculates an allowable output power (WoutA) of the secondary battery before a ripple temperature increase operation for increasing the temperature of a secondary battery by causing a ripple current to flow in the secondary battery is performed, the allowable output power being determined in advance based on the temperature and a state of charge (SOC) of the secondary battery. A second calculating section (120) calculates the allowable output power (WoutB) achieved when the ripple temperature increase operation is performed. A determining section (122) determines whether to perform the ripple temperature increase operation so that when the allowable output power (WoutB) is equal to or greater than the allowable output power (WoutA), the ripple temperature increase operation is performed and, when the allowable output power (WoutB) is smaller than the allowable output power (WoutA), the ripple temperature increase operation is not performed.

    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.

    摘要: An ECU calculates an evaluation value decrease amount D(−) in response to a reduction of unevenness of lithium ion concentration caused by diffusion of lithium ions resulting from a lapse of one cycle time ΔT, calculates an evaluation value increase amount D(+) in response to an increase of the unevenness of the lithium ion concentration caused by discharging during a lapse of one cycle time ΔT, and calculates a present value D(N) of a battery deterioration evaluation value D due to high-rate discharging, as a previous value D(N−1)−evaluation value decrease amount D(−)+evaluation value increase amount D(+). If battery deterioration evaluation value D exceeds a predetermined target value E, the ECU sets a discharging power limit value WOUT that is a limit value of electric power to be discharged from a battery, to a value lower than a maximum value W(MAX).

    摘要: During use of a secondary battery, a concentration change ratio estimating unit estimates a ratio of change in electrolytic solution concentration based on a charging/discharging current. According to the estimated ratio of change, a concentration estimated value calculating unit sequentially calculates an electrolytic solution concentration estimated value during the use of the secondary battery. Based on the estimated electrolytic solution concentration estimated value, a determining unit determines whether or not the electrolytic solution concentration is within a normal range. When the electrolytic solution concentration is outside the normal range, a charging/discharging condition modifying unit modifies a charging/discharging condition of the secondary battery to bring the electrolytic solution concentration back to the normal range, thus avoiding a tendency of overcharge or a tendency of overdischarge.

    摘要: A diffusion estimation unit follows a diffusion equation in an active material that is represented by a polar coordinate to estimate a distribution in concentration of lithium in the active material. An open circuit voltage estimation unit obtains an open circuit voltage in accordance with a local SOC(θ) based on a concentration of lithium obtained at an interface of the active material as estimated by the diffusion estimation unit. A current estimation unit uses a battery's voltage measured by a voltage sensor, the estimated open circuit voltage, and a parameter value that is set for the battery by a battery parameter value setting unit, and follows a voltage-current relationship model expression simplified from an electrochemical reaction expression to estimate the battery's current density. A boundary condition setting unit sequentially sets a boundary condition for the diffusion equation of the diffusion estimation unit for the active material's interface, as based on the battery's estimated current density. Thus a battery model that allows an internal state to be estimated based on an electrochemical reaction dynamically and can also achieve an alleviated operating load can be used to estimate a state of a secondary battery.
