摘要： An internal short-circuit determination circuit includes a current detecting unit, a voltage detecting unit, a short detecting unit, and first and second acquiring units. The first acquiring unit acquires first and second capacity values based on first and second voltage values. The second acquiring unit acquires a third capacity value based on a current flowing in a battery unit during a predetermined period. The short detecting unit computes a fourth capacity value by subtracting at least the second and third capacity values from the first capacity value. The short detecting unit determines whether an internal short-circuit has occurred in the battery unit based on the fourth capacity value.
