    摘要： A status detector for a power supply, a power supply, and an initial characteristic extracting device for use with the power supply, each of which can detect the status of an electricity accumulating unit with high accuracy by sequentially modifying characteristic information necessary for the status detection of the electricity accumulating unit. A measuring unit obtains measured values of at least current, voltage and temperature of the electricity accumulating unit. A processing unit executes status detection of the electricity accumulating unit by using the measured values and the characteristic information of the electricity accumulating unit which is stored in a memory unit. A discrepancy detecting unit detects the presence of a discrepancy away from a theoretical value when a result of the status detection obtained by the processing unit is changed over a predetermined threshold or reversed with respect to the measured values obtained by the measuring unit. A modifying unit modifies the characteristic information stored in the memory unit depending on the discrepancy detected by the discrepancy detecting unit.

    摘要： An object of the present invention is to provide a storage battery managing apparatus that can ensure charge-discharge control of a storage battery in consideration of state variation of each unit cell even if the battery pack includes a number of component unit cells, and a vehicle controlling apparatus providing the same. A storage battery 110 includes a plurality of chargeable-dischargeable unit cells connected. Battery management ICs 122 detect the cell voltage of each unit cell. A voltage sensor 150 detects a storage battery voltage. A current sensor 140 detects currents to be charged and discharged in the storage battery. Processing means 132 obtains a degree of SOC imbalance by use of the cell voltage of each unit cell detected by the battery management ICs 122 when the storage battery is being neither charged nor discharged. The processing means 132 calculates highest and lowest SOCs from the average SOC obtained from the storage battery voltage detected by the voltage sensor 150 and the degree of SOC imbalance when the storage battery is being charged or discharged.

    摘要： A battery management system which can output a battery state enabling optimum charge and discharge control to be performed even when a temperature variation occurs among individual single cells. A plurality of temperature sensors measure temperature values of a battery. A measurement unit measures a voltage and a current of the battery. A maximum/minimum temperature selection unit in a calculation unit determines a maximum temperature and a minimum temperature from the temperature values measured by the temperature sensors. An available power calculation unit calculates respective values of maximum available charge and discharge powers or maximum available charge and discharge currents of the battery corresponding to the maximum temperature and the minimum temperature based on the voltage and the current of the battery. A selection unit selects and outputs smaller maximum available charge and discharge powers or smaller maximum available charge and discharge currents from the respective values of the maximum available charge and discharge powers or the maximum available charge and discharge currents of the battery corresponding to the maximum temperature and the minimum temperature, which are calculated by the calculation unit.
