Abstract:
A charge control device of one example of the present invention comprises a temperature detection unit, a storage unit, and an upper limit setting unit. The storage unit stores a reference current characteristic and at least one of a first current characteristic and a second current characteristic as a charging current characteristic, and stores a reference voltage characteristic and at least one of a first voltage characteristic and a second voltage characteristic as a charging voltage characteristic. The upper limit setting unit selects a characteristic used to set upper limits of a charging current and a charging voltage to the battery from among a plurality of the charging current characteristics and a plurality of the charging voltage characteristics stored in the storage unit.
