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.
