ABSTRACT:
A diagnostic apparatus for determining a battery charge status of a battery set, includes a no-load voltage calculating section for detecting no-load voltage VCn of cells; a first judging section for determining whether a battery state of each of the cells C is normal or abnormal based on the cell no-load voltage VCn calculated by the no-load voltage calculating section; and a second judging section for determining that a battery module including the cell determined to be abnormal by the first judging section is an abnormal battery module which is necessary to be exchanged. Further, the battery state diagnostic apparatus may also include a third judging section for determining a battery set is an abnormal battery set which is necessary to be exchanged when the number of battery modules determined to be abnormal is equal to or greater than a predetermined number, and calculating section for calculating the average voltage value of a plurality of battery modules determined to be normal based on the cell no-load voltage VCn.
