Abstract: A charging adapter includes a first coupler, a second coupler, a power delivery path, an arithmetic circuit, and a transmission circuit. The first coupler is detachably coupled to a power delivery adapter. The power delivery adapter outputs a DC voltage. The second coupler is detachably coupled to a battery pack. The power delivery path electrically couples the first coupler to the second coupler. The arithmetic circuit calculates a control parameter of the power delivery adapter based on a state of the battery pack coupled to the second coupler. The transmission circuit transmits the calculated control parameter to the power delivery adapter through the first coupler.

Abstract: A charger according to one aspect of the present disclosure includes a current outputter, a first charge controller, and a second charge controller. The first charge controller receives a first required information from a first device in accordance with a first communication protocol. The first communication protocol requires at least a first minimum volume of communication to acquire the first required information from the first device. The second charge controller receives a second required information from a second device in accordance with a second communication protocol. The second communication protocol requires at least a second minimum volume of communication to acquire a second required information from the second device. The second minimum volume is smaller than the first minimum volume.
