    摘要: A dynamic hibernation time apparatus monitors and ensures that battery packs in a computer system have sufficient energy capacity to sustain a proper saving of the hibernation file into the hard disk drive. The invention determines the memory size of the computer and adds the storage space needed to store the chip register contents to arrive at the determination of the hibernation file size. Next, the time necessary to save the hibernation file on the disk data storage device and the hibernation energy required to operate the disk data storage device to completely save the hibernation file are determined. When the battery capacity drops within a range of the previously computed hibernation energy, a warning message is generated at the user and the hibernation file is saved. The computer is shut down after the hibernation file has been properly saved. Thus, by determining the total memory size to be saved in the hibernation file, by determining the time and the energy required to completely store the hibernation file into the disk drive, and by sensing either the battery capacity or requesting that the smart battery sends an alarm to initiate the hibernation file saving process, the present invention ensures that sufficient energy exists in the battery packs to properly save the hibernation file onto the hard disk drive before system shut down occurs due to low battery capacity without wasting energy by determining the set point based on a maximum memory configuration.

    摘要: A computer system including circuitry for accurately and economically controlling the charge voltage and charge current at the terminals of its rechargeable battery. During a battery recharge, sensor circuitry coupled to the battery provides accurate data to a battery microcontroller regarding the charge voltage and charge current present at the battery terminals. A battery microcontroller relays this information to a multipurpose microcontroller. The battery microcontroller also provides the desired charging voltage and current as determined by the battery pack's charging algorithm. The multipurpose microcontroller uses the battery status information to program an addressable potentiometer. In turn, the potentiometer generates an adjustment signal that controls the output voltage of the computer's AC adapter. Preferably, the AC adapter is capable of being operated in a constant-power mode. Adjustment of the potentiometer allows the output of the AC adapter to be dithered up or down as needed to provide the desired charging voltage and charging current to the battery.

    摘要: The present invention relates to circuitry for selecting a master battery pack for supplying power to a computer system capable of incorporating multiple battery packs. A bi-directional master battery signal is communicated to the microcontroller of each installed battery pack and arbitration circuitry contained within the host computer system. The master battery signal operates in conjunction with a serial communications interface between each of the installed battery packs and the host computer system. Battery status information is communicated to the host computer system via the serial communications interface, and the host computer system then selects a master battery pack. The battery pack selected to be the master asserts the master battery signal while all other battery packs monitor this signal waiting for it to be deasserted. Other battery packs utilize the master battery signal to control their own charge and discharge circuitry. Deassertion of the master battery signal denotes that the master battery pack is no longer capable of supplying power to the host computer system and the master battery pack arbitration process is repeated.

    摘要: A power supply system, for example, for use with a portable personal computer, includes a smart battery pack and a charging system. The smart battery pack is provided with a dedicated microcontroller for controlling the charging level of the battery charger system. In particular, the status of the battery including the voltage and temperature of the battery is applied to the microcontroller along with a signal representative of the current load demand of the computer system. The micro controller, in turn, provides a control signal in the form of fixed frequency, variable duty cycle pulse width modulated (PWM) signal for controlling the charging level of the battery charger system. The duty cycle of the PWM signal is used to regulate the charging current supplied by the battery charger. In particular, the DC value of the PWM signal is used as a reference to control the charging current of the regulator to provide a variable output charging current with a relatively wide current range. As such, the battery charger is adapted to efficiently utilize the residual capacity of the battery charger system for optimizing charging of the battery packs during all operating conditions of the computer system. Moreover, the use of a PWM signal from the battery pack to control the battery charger enables a single type of battery charger to be utilized for various battery technologies.
