Abstract: A circuit board includes an electronic component and a printed wiring board to which the electronic component is mounted by soldering. The electronic component includes a pad electrode disposed at a bottom portion of a body part. The pad electrode has a leading end electrode part laterally protruding from a first side face of the body part, and an internal electrode part provided integrally with the leading end electrode part and positioned at a bottom face of the body part. The printed wiring board has, on a substrate, a first pad and a second pad provided so as to be separated from the first pad. The leading end electrode part is joined to the first pad by soldering and the internal electrode part is joined to the second pad by soldering.

Abstract: A charging system supplies a charge current from a power supply to a power storing apparatus. A shunt resistor is connected to a charging path through which the charge current flows. An amplifier is configured to amplify a voltage across the shunt resistor. A controller is configured to control the charging circuit on a basis of an output from the amplifier. A power supplying circuit is configured to supply a drive voltage to the amplifier. The power supplying circuit includes a first feed path including a diode connected between an input terminal and a power supply terminal of the amplifier and a second feed path including a switch connected between the power storing apparatus and the power supply terminal of the amplifier. The switch is configured to be turned on when a charge voltage of the power storing apparatus exceeds a threshold voltage.

Abstract: The electricity storage device control circuit includes a voltage detector and a voltage controller. The voltage detector is configured to detect voltages of a plurality of electricity storage devices. The voltage controller is configured to individually control the voltages of the plurality of electricity storage devices by performing, based on a detection result by the voltage detector, at least one of discharging or charging of electrostatic energy stored in the plurality of electricity storage devices.
