Abstract
Rapid determination of the condition or charge parameters of a battery, such as the present charge of the battery and the maximum charge capacity of the battery. A plurality of discharge pulses (,) and a plurality of rest periods (,) are applied to the battery. The battery voltage is then measured to provide voltages (,) during the rest periods, and/or voltages (,) during the discharge pulses. The voltage difference among selected one of the voltages are used to provide a difference voltage DELTA-L. The difference voltage DELTA-L is then used to determine a charge parameter of the battery, such as the maximum charge capacity or condition of the battery and the present charge in the battery. This information is then displayed to a user so that the user will know the present capacity and the present charge of the battery and can make an informed decision as to whether the battery is adequate for the project that the user has in mind, or to a subsequent process, such as a charging process.
