A battery monitoring system determines an accurate residual capacity of a battery in consideration of variation of battery temperature, amount of battery self-discharge, and amount of battery discharge from a host device, such as a portable computer. The monitoring system further determines a predicted remaining operating time of the device. The battery capacity measuring apparatus includes a microcontroller, a battery pack, a battery temperature detection circuit, a battery voltage detection circuit, a load current detection circuit, and a power saving level detector. The microcontroller is coupled to a host device such that it indicates the battery residual capacity along with the remaining operating time of the device via a display. The microcontroller calculates the residual capacity of the battery based on the detected battery voltage and a correction is made to the calculated residual capacity according to the battery temperature signal and the load current signal, the corrected resultant residual capacity being fed to the host device so as to display the residual capacity of the battery. Also, the microcontroller calculates the remaining operating time of the device based on the detected load current and a correction is made thereto according to the set power saving level of the device, the resultant remaining operating time being fed to the host device so as to display the corrected remaining operating time of the device.

Monitoring technique for accurately determining residual capacity of a battery

A battery pack and a method of operating a battery system. The battery pack includes a rechargeable battery and a processor for monitoring the battery during charging and discharging. The processor receives data values representing the battery voltage, temperature and current, and the processor performs a series of calculations using those data values. In one of these calculations, the processor determines the actual full capacity of the battery. Preferably, the processor also keeps track of an uncertainty value that represents an uncertainty in the capacity of the battery; and the processor calculates the actual full capacity of the battery at the end of each discharge cycle if, at that time, the uncertainty value is less than a given percentage of a nominal full capacity of the battery.
