  • Patent number: 8305044
    Abstract: A battery pack includes: an obtaining unit for obtaining computation information for calculating a charge current including temperature information of a battery; a computation unit for computing a charge current for the battery based on the computation information; and a notification unit for notifying a computer of the charge current computed by the computation unit. The notification unit uses a dedicated command to notify the computer of the charge current. The battery pack includes: a storage unit for storing therein a first threshold value and a second threshold value relating to the temperature information, and the computation unit may compute the optimal charge current depending on which of ranges divided by the first threshold value and the second threshold value the temperature information belongs to.

  • Patent number: 8198856
    Abstract: An electronic apparatus is disclosed. The electronic apparatus includes a battery, a main body, a charging section, an obtaining section, and a controlling section. The battery has first information with which charging of the battery is controlled. The main body operates with the battery as a power supply. The charging section charges the battery. The obtaining section obtains the first information from the battery. The controlling section controls the charging section based on the obtained first information and causes the charging section to perform a charging according to another battery.

  • Patent number: 7790309
    Abstract: A battery pack includes a casing formed of an insulative material; a secondary battery disposed inside the casing; a control circuit-board disposed inside the casing and provided for charging and discharging the secondary battery; and a protection sheet formed of an insulative material and disposed inside the casing while being in contact with an outer surface of the secondary battery. The control circuit-board is disposed across from the secondary battery while the protection sheet is disposed therebetween. The external dimension of the protection sheet is greater than the external dimension of the control circuit-board.
