<P>PROBLEM TO BE SOLVED: To protect a secondary battery as much as possible even upon failure of a radiator for use in consuming regenerated power. <P>SOLUTION: Upon the occurrence of a failure in a regenerative power consumption system provided with a radiator, the failure is determined while discriminating a first failure mode requiring emergency and a second failure mode not requiring emergency. Upon the occurrence of a failure in second failure mode, surplus regeneration power Qr is consumed in the radiator. When a battery is charged with the surplus regeneration power Qr, it must be charged with a power exceeding a normal use range momentarily but since the surplus power can be consumed in the radiator, the case for storing the surplus power in the battery can be reduced. Consequently, deterioration of the battery can be suppressed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
