A mobile device driven based on electric power includes a connection section configured to be electrically coupled to an all-solid-state battery having a solid electrolyte, and an obtaining section configured to obtain unique information of the all-solid-state battery electrically coupled to the connection section.

Mobile device

A liquid discharge apparatus includes a drive signal output circuit configured to output a drive signal, a power unit configured to supply a power source voltage to the drive signal output circuit, and a first housing that accommodates the drive signal output circuit, and the power unit. The power unit includes a power supply circuit configured to convert an alternating voltage into a first direct voltage and a second direct voltage, and output the first direct voltage, a substrate on which the power supply circuit is provided, a solid state battery configured to output a third direct voltage corresponding to a stored electric charge, a charging circuit configured to store an electric charge in the solid state battery based on the second direct voltage, and a second housing that accommodates the power supply circuit, the solid state battery, and the charging circuit.

Liquid discharge apparatus, mobile device, and power unit

A mobile device includes a driving circuit, a first accommodation section configured to accommodate a first battery which supplies electric power to the driving circuit and which is an all-solid-state battery having a solid electrolyte, a control circuit configured to control the driving circuit such that driving is performed in one of a plurality of modes including a first mode and a second mode in which power consumption is smaller than the first mode, and a determination circuit configured to determine whether electric power is supplied from an external power source to the first battery. When the determination circuit determines that the electric power is supplied from the external power source to the first battery, the control circuit performs switching from the second mode to the first mode.

A mobile device includes: a drive circuit driven based on power output from a battery; a first coupling portion configured to electrically couple a first battery being an electrolyte battery having a liquid electrolyte as the battery to the drive circuit; and a second coupling portion configured to electrically couple a second battery being an all-solid battery having a solid electrolyte as the battery to the drive circuit.

Mobile device including drive circuit driven by electrolyte battery or all-solid battery

A mobile device includes a drive element, a first battery configured to supply power to the drive element, and a stopping unit stopping supplying of power to the first battery when a voltage of an attachable/detachable second battery configured to supply power to the drive element is greater than or equal to a first voltage for driving the drive element.

A mobile device includes a drive element, a first battery which outputs power, and a supplying unit which supplies the power output by the first battery or power output by a second battery to the drive element, in which the supplying unit prioritizes supplying of the power output by the second battery to the drive element over the power output by the first battery.

A mobile device includes a first processor, a second processor having a smaller power consumption than the first processor, and a first battery capable of supplying power to the first processor and the second processor, in which a distance between the first processor and an attachable/detachable second battery that is capable of being attached and detached and that is capable of configured to supplying power to the first processor and the second processor is longer than a distance between the second processor and the second battery.

Mobile device with battery

A battery charging apparatus that acquires a remaining battery charge amount by detecting a battery voltage after charging of a battery by a charging circuit has been temporarily stopped and a given wait time has elapsed, wherein, regardless of the temporary stopping of charging by the charging circuit, a charging display control unit that controls display of a charging displaying section causes the charging displaying section to display that charging control is being performed while charging control is being performed.

Battery charging apparatus and recording apparatus

A power source is configured to include a plurality of batteries and a switching circuit that switches a state to and from a first state in which the electric power is supplied to the outside by the plurality of batteries being connected in series and a second state in which the electric power is supplied to the outside using remaining batteries without using a part of the plurality of batteries.
