Abstract
A battery monitoring apparatus includes a circuit board, a signal control unit configured to cause a predetermined AC signal to be outputted from a storage battery through a first electrical path, a response signal input unit configured to input, through a pair of second electrical paths, a response signal of the storage battery to the AC signal, and a calculating unit configured to calculate, based on the response signal, a complex impedance of the storage battery. The first and second electrical paths are provided on a major face of the circuit board. On the circuit board, there is defined a first region which is surrounded by the first and second electrical paths and two terminals of the storage battery. The size of the first region is set to have an electromotive force, which is induced in the second electrical paths by the AC signal, be within an allowable electromotive-force range.
