BATTERY ABNORMALITY PREDICTION SYSTEM

A battery abnormality prediction system includes a normal range determination unit which acquires parameter values representing the states of a plurality of unit cells (11a to 11-n (where n is a natural number equal to or greater than 2)) and determines whether or not the acquired parameter values are normal values, a statistical processing unit which sorts a plurality of parameter values determined to be normal values into ranges divided at predetermined intervals and performs statistical processing on the sorted parameter values, and a state determination unit which determines the states of the plurality of unit cells based on the result of the statistical processing in the statistical processing unit and determines whether or not the plurality of unit cells are in a state of being able to transit from a normal state to an abnormal state based on the determination result.
