There is a demand for an information processing device capable of maintaining, as long as possible, a state in which a decrease an the processing speed of a CPU due to heat generation hardly occurs. Therefore, proposed is an information processing device including a secondary battery, and the information processing device includes a measurement unit that measures a remaining amount of the secondary battery, a determination unit that determines whether or not the remaining amount is equal to or more than a first threshold and determines whether or not a specific application is in a foreground state, and a charge control unit that stops charging the secondary battery by using an external power supply in a case where the remaining amount is equal to or more than the first threshold and the specific application is in the foreground state.

A microcontroller, processor, and/or software (SW) monitors a battery degradation indicator such as battery State-Of-Health (SOH), impedance or other attributes, and calculates battery degradation rate and regulates burst power, battery charging speed and/or battery charging limit to meet users' expectation of battery service life. The microcontroller, processor, and/or SW increases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is smaller than expected and there is more longevity budget than expected. In another example, the microcontroller, processor, and/or SW decreases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is greater than expected and there is less longevity budget than expected.

A charging control method includes: converting an input power to a DC power; receiving the DC power by a detachable cable to generate a bus power; converting the bus power to a charging power for charging a battery in a charging period; and adjusting the DC power and/or the charging power to track a maximum of a power conversion efficiency; wherein the power conversion efficiency includes one of the following: an input power conversion efficiency, which is a conversion efficiency of converting the input power to the charging power; a DC power conversion efficiency, which is a conversion efficiency of converting the DC power to the charging power; or a bus power conversion efficiency, which is a conversion efficiency of converting the bus power to the charging power.

A charging apparatus having a backup function includes a first connecting interface, a second connecting interface, a processing unit, a memory unit, and an authorizing unit. The first connecting interface is adapted to receive a power source. When the processing unit authorizes the first electronic device, the processing unit activates the backup function to back up data stored on a first electronic device connected to the second connecting interface into the memory unit. Hence, a user can use the charging apparatus to charge the first electronic device, and to back up the data stored on the first electronic device into the memory unit or to restore the data stored on the memory unit into the first electronic. The user of the first electronic device can effortlessly enjoy the data backup and restore functionality.

A wiring device including a first printed circuit board (PCB) that includes a first direct current (DC) output port and a second DC output port. The wiring device further includes a second PCB electrically connected with the first PCB, the second PCB including a planar transformer integrated with a surface of the second PCB and configured to output power at one or more DC voltage levels, a switch connected to the planar transformer, and a microcontroller. The microcontroller includes an electronic processor and is configured to control delivery of power from the planar transformer to at least one of the first DC output port and the second DC output port using the switch. The switch may have a Gallium Nitride (GaN) chemistry or a Silicon Carbide (SiC) chemistry.
