    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.

    摘要: A trickle wait state (225) is included in a charging routine (200) prior to initiating any rapid charge of the battery (234). The wait state (225) allows the battery temperature (Rt) to reach equilibrium with the ambient temperature (214-224) before application of any rapid charge current to the battery so that .DELTA.T/.DELTA.t termination can be used, even in an uncontrolled temperature environment. The wait state (225) trickle charges (216) the battery for a time interval (218) and measures and stores the battery temperature before and after this time interval (214, 220). The battery continues to be trickle charged until the battery temperature reaches equilibrium with the temperature of the environment (222), at which time rapid charging (234) of the battery can commence.

    摘要: A battery charging system (300) provides an expanded range of battery recognition between a charger (302) and a battery (304). Two resistors (316, 318) are coupled in series across the positive and negative charging terminals (B+, B-) of the battery (304) such that when the battery is coupled to the charger (302) there is provided a voltage divider to an A/D port (332) which is used to determine the battery type. Initially, the charger (302) disables charge current to the battery (304) and the charger determines the first resistor (316) value by enabling a switching circuit (336) and reading A/D port (332). Current is then enabled through positive charge node (B+) with the switching circuit (336) switched off, and the value of second resistor (318) is determined. The two resistors (316, 318) provide for an expanded range within which the A/D port (332) can determine battery type. A second charging system (400) provides an expanded battery type recognition range in a three contact charging system.

    摘要: A battery charging system (200) is capable of maintaining a fully charged battery (202) without overcharging or undercharging the battery regardless of the operating mode of the radio (204). Charging system (200) includes a charger (202) which senses the capacity of the battery (206) through a capacity resistor (224) at a capacity sense terminal (244). The charger (202) also senses the radio current through the same capacity sense terminal (244) using a current sensing device (226). Charger (202) continuously compensates for the current drain presented by the radio (204).

    摘要: A battery charging system includes a battery pack (106) and charger (102). Battery pack (106) includes a selectable magnetic field generator (202) which is activated by radio controller (206) when radio (104) changes states. A Hall-effect switch (204) located in either charger (102) or battery (106) receives the magnetic field and informs charger monitor circuit (128) that radio (104) has changed states. This allows for charger (102) to modify the amount of current being provided to radio (104) via line (129). In a second embodiment, an infrared source (402) and an infrared detector (404) are used in place of selectable magnetic field generator (202) and Hall-effect switch (204).

    摘要: A battery charging system (200) includes a field-effect transistor (212) as a current discharge protection device in order to prevent current from flowing from battery (222) to charger (202) when charger (202) is not charging or discharging battery (222). The field-effect transistor (212) also protects battery (222) in the case that the battery contacts are inadvertently shorted. When charger (202) is charging battery (222), field-effect transistor (212) is turned on, providing for reduced voltage drop across the device due to its low on resistance, and also allows for charger (202) to charge and discharge (condition) battery (222).
