Abstract
A storage battery managing apparatus which ensures 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 includes a plurality of chargeable-dischargeable unit cells connected in which battery management ICs detect the cell voltage of each unit cell, a voltage sensor detects a storage battery voltage and a current sensor detects currents to be charged and discharged in the storage battery. A degree of SOC imbalance is obtained by use of detected cell voltage of each unit cell when the storage battery is being neither charged nor discharged.
