摘要:
A battery charge circuit using a constant voltage/constant current to power charge a plurality of battery packs, a current detection circuit to detect a charge current according to a predetermined value, and control mechanisms to maintain a constant voltage charge mode when the charge current value drops below a set value within the battery pack.

According to one embodiment, television receiver includes: display; flat housing; first member; second member; and electric component. The first member includes an opening through which a screen is exposed and a first wall extending in a thickness direction of the housing between one end of the housing at which the opening is provided and another end of the housing opposite the one end. The first wall covers a circumference of the display. The second member includes a second wall located on the other end and covers the display from an opposite side of the screen. The electric component includes a component surface extending along an internal surface of the second wall on a side of the display away from a center of the internal surface. The component surface is adhered to the internal surface.
摘要:
In a battery-driven portable computer, a battery pack is constituted by m battery sets connected in series each including n lithium-ion secondary battery cells connected in parallel. A voltage monitor for monitoring the voltage of the terminal electrode of each battery set and a charger for independently appropriately charging each battery set in accordance with a monitor result are arranged, thereby realizing battery driving by a lithium-ion secondary battery pack having a large capacity. A computer system monitors the voltages of the battery cells which are part of a secondary battery by comparing the battery voltages with a predetermined voltage value in order to detect overdischarge (undervoltage) or overcharge (overvoltage), outputs this information outside of the battery pack, and terminates processing prior to a circuit disconnect.
