This invention is used to control the duration of time it takes to charge any device, depending on how many units the user has taken out of their fitness goal. This invention connects to a fitness device such as a smart watch and retrieves the amount of units the user has completed. Being conditional on how many units the user has taken, the device will either charge at a normal pace or proportionally slower. For example, if the user's daily goal was 10,000 units and they completed 5,000 units, their device would charge half its normal pace. This invention charges the device more slowly by pausing the charges for periods of time.

A control device includes a first acquisition unit configured to acquire geographical position information of a battery registered as being mounted in an electric power supply target, a second acquisition unit configured to acquire geographical position information of the electric power supply target having the battery mounted therein, a determination unit configured to determine whether a change has occurred in a relative relationship between the geographical position information of the battery acquired by the first acquisition unit and the geographical position information of the electric power supply target acquired by the second acquisition unit, and a coping unit configured to stop supply of power to the electric power supply target having the battery mounted therein in a case where it is determined by the determination unit that a change has occurred in the relative relationship.

A power supply unit for an aerosol inhaler includes: a case; a power supply that discharges power to a load for generating an aerosol from an aerosol generation source; a discharging terminal that connects the load to the power supply; a charging terminal that connects the power supply to an external power supply and is separated from the discharging terminal; a temperature measuring unit that measures temperature of the power supply; and a control device that controls an effective value of a first charging current to a value smaller than an effective value of a second charging current. The first charging current is supplied to the power supply when a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second charging current is supplied to the power supply when the measurement value is lower than the first threshold.

The present invention is a system and method for formation and packaging of a rechargeable battery. Battery is packaged with multiple modules with each module containing cells of different sizes. A controller reads the state of charge of battery modules and if state of charge is low, battery modules with smaller cells are charged first. The system is comprising of battery modules with each module holding one size cells and the package holding modules of different cell sizes. It is possible to have each module formed with different cell sizes as well. Logics in the controller memory determines the recharging sequence of the battery modules and send charging command to recharging hardware.
