摘要： A controller of a card radio modem connectable to a data terminal measures two kinds of a battery voltage under a different load condition of the card radio modem. The controller determines the kind of battery and detects the remaining time of accuracy, based on the kind of the battery. In addition, the controller calculates an available capacity of a file data to be transmitted and received during the remaining time. When the available capacity is smaller than a capacity which is necessary to transmit and receive, the controller generates an alarm to inform an operator. The controller displays the available capacity or remaining time on a display.

摘要： A method of and an apparatus for monitoring the state of charge of a rechargeable battery are disclosed which use a reference value corresponding to a defined state of charge stored in a memory. During each battery charging and discharging cycle, the terminal voltage, the current and time are measured and are converted into energy delivered to the battery or by the battery depending on the direction of current flow. The actual state of charge is then calculated from the reference value stored. The characteristic terminal voltage curve during charging and discharging is used for minimizing the differences between the quantities measured and the actual state of charge of the battery so monitored by monitoring the rate of change in the terminal voltage during the charging and the discharging cycles, by determining, after a phase of a relatively steady and small rate of change in voltage, at least one point at which the rate of change in voltage is higher and by adjusting the actual state of charge determined at this point by coulometry to the predetermined reference value.

摘要： This specification discloses a method and apparatus for testing batteries in which a diagnostic cycle includes a discharge cycle and a charge cycle of five charging pulses and another discharge cycle. The discharge cycle durations are respectively one and twenty seconds. A typical duration for the charge cycle is 80 milliseconds. A plurality of voltages measured during this diagnostic cycle are used to evaluate five arithmetic functions. The results of the evaluation of three of the functions are compared against predetermined limits to determine battery quality. Additionally, the results of the evaluation of the remaining two functions are compared with one another to establish whether or not the battery is defective. This test provides a substantial advantage over prior art tests in that the test is substantially independent of battery temperature and battery size.
