    摘要: A battery pack (110) having a plurality of cells (103, 105) utilizes a pull up resistor (116) multiplexed between separate voltage supply sources (120, 122) and a single battery contact (106) to monitor individual cell temperatures. A plurality of thermistors (102, 104) are coupled in series between ground potential (108) and the single battery pack contact (106), each thermistor being coupled to one cell of the pack. Individual voltage divider circuits are formed for each thermistor (102, 104) as the pull up resistor (116) is multiplexed between the voltage supply sources (120, 122).

In one arrangement, the method can include the steps of coupling (311) the battery to a first power supply (114), coupling (311) the battery to a second power supply (116), determining (312) an available charging current parameter for the battery and selectively enabling (314) a charging circuit (120) for the first power supply and a charging circuit (122) for the second power supply based on the available charging current parameter of the battery.

    摘要: A host device (500) is coupled to a peripheral device (104) which is initially not identified. To identify the peripheral device, the host device uses known information and information acquired from the peripheral device to determine the values of several electrical components (122) in the peripheral device. The host device applies different electrical conditions to the components by adjusting the state of I/O ports coupled to the peripheral device and measuring electrical conditions in response at other ports. Once sufficient information has been acquired, the measured values are used with known values of the system to calculate the values of the components in the peripheral device according to known electrical relationships.

    摘要: A charging technique (200) charges a battery pack (102) by taking into account the additional internal circuit impedance of the battery pack. An optimum pack voltage value for the battery pack is calculated (208) based on the rated internal cell voltage as well as the charge current and the internal battery pack circuitry impedance. The battery pack can now be charged such that the internal battery cell voltage is maintained at the rated voltage throughout the charging process. The optimum pack voltage is also updated (220) to account for variations in the battery pack circuitry impedance over temperature (216, 218) as well as variations in charge current (222, 224) during the charging process.
