Patent number: 11728669Abstract: A charger includes a first connection portion, a second connection portion, a power-supply circuit, an integration circuit, a storage device, a first calculation circuit, a threshold setting circuit, a detection circuit, and a reduction circuit. The power-supply circuit includes a heat-generating component. At a start of charging a battery, the first calculation circuit calculates a first detection threshold candidate based on a first correspondence data (or a first correlation data). The first detection threshold candidate corresponds to a first temperature threshold that is calculated, with a calculated integrated capacity assigned to a battery capacity, based on the first correspondence data. The threshold setting circuit sets the first detection threshold candidate as a detection threshold. The reduction circuit performs reduction of a charging current value in response to a detected temperature of the heat-generating component having become higher than or equal to the detection threshold.Type: GrantFiled: September 13, 2021Date of Patent: August 15, 2023Assignee: MAKITA CORPORATIONInventors: Hisakazu Okabayashi, Masaya Mizutani
