    摘要： A battery use system for a battery-driven portable electronic equipment includes a first battery (1) chargeable and serving as a direct power supply source, a second battery (2) parallelly connected to the first battery through a switch (3), a voltage detection circuit (4) for detecting an output voltage from the first battery, a consumption current detection circuit (5) for detecting the state of the consumption current of the portable electronic equipment, and a switch control circuit (6) for controlling open and close of the switch in accordance with an output from the voltage detection circuit and an output from the consumption current detection circuit. The switch is closed to charge the first battery by the second battery when the output voltage from the first battery becomes smaller than a predetermined value, and at the same time, the consumption current is sufficiently small.

    摘要： A power management system automatically manages the power to operate a biomedical device, such as an infusion pump containing an internal battery. When external power is available, the management system operates the biomedical device from the external power and controls a recharger to maintain the battery at full charge. The power management system automatically calculates battery charge status and use and provides a run time display of the calculated amount of time that the battery can operate the biomedical device under current power requirements of the biomedical device. The power management system automatically updates the calculated charge status of the battery as well as the calculated capacity of the battery based on environmental factors and battery characteristics. The power management system automatically and periodically performs a deep discharge/recharge cycle to refresh the battery.

    摘要： The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).

    摘要： 5 n7 An adapter for selectively connecting an external battery which is used as a power source of a portable notebook type computer to the computer or a charger, and an external battery system for controlling the connection between the adapter, the computer and the charger. The external battery is connectable to the adapter, and the adapter is connected to either the charger or the computer. A diode for selectively regulating either the direction for charging the external battery or the direction for introducing the power from the external battery is provided within the adapter. The adapter, the charger and the computer are selectively connected with each other by a common cable. There are three typical connection modes. In the mode A, the charger supplies a power to the computer. If the computer is being operated, the charger directly supplies a power of a constant voltage to the group of devices in the computer. If the computer is in an inoperative state, the charger supplies a power of a constant current for charging the internal battery. In the mode B, the charger charges the external battery through the adapter and outputs a power of a constant current. In the mode C, the power from the external battery is supplied to the computer through the adapter. The external battery is connected to the group of devices in parallel with the internal battery. Both batteries are operated in cooperation with each other. After the external battery is connected to the computer, the computer keeps on operating even if the internal battery is removed. Thus, it is unnecessary to back up the data in the computer.
