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 charging adapter in one aspect includes a first coupler, a second coupler, a power delivery path, a converter, a communication circuit, a charging control circuit, a control power supply, a first switch, a first internal path, a second internal path, a second switch, and a starter circuit. The charging control circuit performs a charging control of a battery pack. The charging control includes switching the converter to a first state or a second state. The converter in the first state receives a DC voltage from a power delivery adapter through the first coupler, converts the DC voltage into a charging voltage for charging the battery pack, and outputs the charging voltage to the second coupler. The converter in the second state receives the DC voltage from the power delivery adapter through the first coupler and outputs the DC voltage to the second coupler.

Abstract: A rechargeable cleaner includes a body, a rechargeable battery, a charger, and a body controller. The body is configured to generate suction power capable of sucking dust together with air using a motor. The rechargeable battery is configured to supply electric power to the motor. The charger is configured to charge the battery. The body controller is disposed in the body. The body controller controls at least one of a charging current and a charging voltage based on cell voltage information indicating a cell voltage, cell temperature information indicating a cell temperature, and battery identification information for identifying the battery that are acquired from the battery, and based on charger identification information for identifying the charger acquired from the charger.
