ABNORMALITY PREDICTION SYSTEM FOR SECONDARY BATTERIES
First Claim
1. An abnormality prediction system for a plurality of secondary batteries, comprising:
- a parameter value detection portion that detects parameter values respectively corresponding to each of the plurality of secondary batteries, and that determines whether all the parameter values are normal or not; and
a singular state determination portion that determines, if a difference between a reference value calculated by use of all the parameter values determined to be normal by the parameter value detection portion and at least one of the parameter values is not less than a threshold value, the secondary battery corresponding to the parameter value with the difference not less than the threshold value to be in a state different from those of other secondary batteries out of the plurality of secondary batteries.

Abstract
An abnormality prediction system for secondary batteries according to the present invention includes: a parameter value detection portion that detects parameter values each corresponding to each of a plurality of secondary batteries to determine whether all the parameter values are normal or not; and a singular state determination portion that determines, if a difference between a reference value calculated by use of all the parameter values determined to be normal by the parameter value detection portion and at least one of the parameter values is not less than a threshold value, the secondary battery corresponding to the parameter value with the difference not less than the threshold value to be in a state different from those of the other secondary batteries out of the plurality of secondary batteries.

8. An abnormality prediction system for a plurality of secondary batteries, comprising:
-
a parameter value detection portion that detects parameter values corresponding to each of the plurality of secondary batteries; a parameter value obtaining portion that obtains the parameter values and determines whether the parameter values are in normal range or not; and a singular state determination portion that determines, based on the parameter values which are determined to be in normal, whether one of the secondary batteries is in a singular state or not, the singular state being a state where the parameter value of the secondary battery is away from those of other secondary batteries during the time in which the parameter values are in the normal range. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
