    摘要: A state detection device for power supply system comprises: a measurement unit that obtains current, voltage, and temperature at a chargeable and dischargeable power storage unit as measurement values; a storage unit that stores property information of the power storage unit; an arithmetic unit that uses different methods to calculate first and second states of charge for the power storage unit based upon the measurement values and the property information; a conflict detection unit that detects a conflict in an event that a difference between the first state of charge and the second state of charge is equal to or greater than a predetermined threshold; and a correction unit that corrects the property information during charging or discharging of the power storage unit in response to the conflict having been detected by the conflict detection 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.
