PROBLEM TO BE SOLVED: To suppress deterioration of a battery where abnormality does not occur, while maintaining power supply from the battery where abnormality does not occur, to an electrical machine in the case where abnormality occurs in any one of a plurality of batteries which are connected in parallel.SOLUTION: At normal time in which abnormality does not occur in all of a plurality of batteries, a whole output upper limit value Wout is computed from a total sum of individual output upper limit values Wout(n) (S100) and at abnormal time in which abnormality occurs in any one of the plurality of batteries, the whole output upper limit value Wout is computed by multiplying the total sum of the individual output upper limit values Wout(n) of the batteries where abnormality does not occur, by a correction coefficient kout which is larger than a value 0 and smaller than a value 1 (S130). At abnormal time, the whole output upper limit value or an input upper limit value is made smaller than one obtained by using a normal computation method, such that deterioration of a battery where abnormality does not occur can be prevented from progressing. |
