Abstract: 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.

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.

Abstract: This disclosure describes, in part, techniques for reducing pulsating currents of internal power sources, such as batteries. For example, a device may include a power source, a load, and a control device located between the power source and the load. The control device may include a power converter that is configured to maintain a constant input current from the power source and output a pulsating current to the load.

If the average output power is equal to the reference power, then the control device may cause the power converter to maintain the constant input current. However, if the average output power is different than the reference power, then the control device may cause the power converter to alter (e.g., decrease/increase) the input current being received from the power source.
