Abstract
A battery abnormality detection system includes the following constituents. A battery data acquisition unit acquires voltages of one of a plurality of cells and a plurality of parallel cell blocks in a battery pack and temperatures at a plurality of observation points respectively measured by a plurality of temperature sensors provided in the battery pack. A determination unit determines presence or absence of an abnormality in one of a specific cell and a specific parallel cell block, based on a transition of a voltage of the one of the specific cell and the specific parallel cell block in a predetermined period in the battery pack and on a difference between a temperature change at a first observation point and a temperature change at a second observation point in the predetermined period in the battery pack.
