In order to prevent cell batteries from reaching a regeneration inhibiting voltage in an initial period of regeneration braking and to ensure that a large amount of regeneration can be secured even if characteristics of cell batteries are varied, when a vehicle braking request is received (S2-2), a first limit of regeneration power (S2-8) for which the amount of regeneration is relatively small is performed, and while regeneration control is being performed, information about the cell batteries such as voltage across terminals is acquired from a battery monitoring device to identify a cell battery of which the voltage across terminals becomes the highest among the multiple cell batteries. After the determination is completed (S2-5), the process proceeds to a second regeneration control (S2-9). In the second regeneration control, regeneration is performed by using an upper limit amount of regeneration with which an identified worst cell battery would not reach the regeneration inhibiting voltage as a limiting value.
