    摘要： A charge control device (40A, 40B, 50) is provided that controls charging and discharging of a storage battery (10) in which a plurality of storage blocks (12A to 12N), each including a plurality of cells (11), are connected in series. The charge control device includes voltage sensors (40A, 40B) that detect voltage values of the storage blocks (12A, 12B), respectively, wherein a charge and discharge process is performed in which a charge mode, in which the storage battery is charged, and a discharge mode, in which the storage battery is discharged, are alternately selected, and in which one of the charge mode and the discharge mode is switched to the other mode based on the amount of difference between the voltage values detected by the voltage sensors (40A, 40B).

    摘要： The correction coefficient α is set such that, when the atmospheric pressure Pa is lower than the threshold pressure Paref, the maximum dischargeable electric power of the battery is made smaller than it is when the atmospheric pressure Pa is equal to or higher than the threshold pressure Paref (S120, S220). Then, the maximum dischargeable electric power Wout of the battery is calculated by multiplying the basic maximum dischargeable electric power Woutb by the correction coefficient α (S140), and the engine and the two motors are controlled such that the required vehicle torque Tr* is produced to propel the hybrid vehicle without discharging electric power from the battery beyond the maximum dischargeable electric power Wout (S150-S210). As such, an excessive decrease in the charge level SOC of the battery can be prevented even when the hybrid vehicle is running in an area where the atmospheric pressure is low, such as high-altitude areas.
