An information processing apparatus includes a power processor, an interface, a detector that detects at least one of a voltage value and a current value on an electric power line which connects the power processor and the interface, and a controller. The controller notifies a swap request for swapping electric power roles with an external device to the external device via the interface in a case where a detection value of the detector indicates an abnormal value while electric power is supplied to the external device via the interface.

An electronic device having an inductive power transfer system to transfer power to a portable device is disclosed. The electronic device includes a first inductive coil for power transfer using an alternating magnetic field. The electronic device further includes a permanent magnet structure for creating a separable magnetic attachment between the electronic device and the portable device having a second inductive coil for inductive power transfer. The permanent magnet structure is positioned around an outer perimeter of the first inductive coil to align the first inductive coil with the second inductive coil in the portable device for inductive power transfer. The permanent magnet structure includes one or more discontinuous arc-shaped permanent magnets assembled to form a full or partial ring shape that includes a gap to impede eddy current generation in the permanent magnet structure by the alternating magnetic field during inductive power transfer.

A power supply unit for an aerosol generation device includes: a power supply configured to supply power to a heater configured to heat an aerosol source; a receptacle configured to receive power for charging the power supply from a plug connected to an external power supply; a charger configured to control charging of the power supply by power received by the receptacle; and a controller. The receptacle and the power supply are connected in parallel with the charger, and the charger is configured to supply power from the receptacle and the power supply to the controller via the charger.

An information processing terminal 100, which is used for after-sales service of an energy storage facility 10 that includes an energy storage unit U including a plurality of energy storage modules M, includes: a display unit 107; and a control unit 101, in which the control unit 101 acquires, from the energy storage facility, a temperature of each of the energy storage modules M after start of operation, the temperature being measured by a temperature sensor 37 provided in each of the energy storage modules M, and in which the control unit 101 displays a temperature distribution of the energy storage unit U on the display unit 107 by a color distribution of display colors of a plurality of blocks B depicting an arrangement of the plurality of energy storage modules M in the energy storage unit U.

An electric working machine in one aspect of the present disclosure includes a motor and a controller. The motor is configured to be electrically coupled to a battery pack and to be driven with electric power from the battery pack. The controller is configured to acquire an internal resistance information of the battery pack and to change control of the motor based on the internal resistance information acquired.

A power supply unit for an aerosol inhaler includes: a power supply that is able to discharge power to a load for generating an aerosol from an aerosol generation source; and a control unit that is configured to control at least one of charging and discharging of the power supply such that the power supply does not become one or both of a fully charged state and a discharging termination state.

The present invention provides a screening method for rechargeable battery cells. A predetermined target capacity 2%˜10% or a charging voltage lower than a nominal voltage of the rechargeable battery cells is adopted to charge the rechargeable battery cells, when approaching fully charged, observing the holding currents for each rechargeable battery cells and then screening the rechargeable battery cells based on the holding currents.

The present disclosure relates to systems, methods, and devices for controlling charging of vehicles, to avoid charging during charge-adverse time periods or during charge restriction events. This can advantageously reduce cost to vehicles owners, and or provide access to reward incentives. Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.
