MONITORING CAPACITY OF A RECHARGEABLE BATTERY

摘要

A method of determining a level of charge remaining on a re-chargeable battery that is operably coupled to a mobile phone. The method comprises the steps of measuring a level of battery charge of the re-chargeable battery, calculating a rate of change of the level of battery charge; and determining a level of charge remaining on a re-chargeable battery by subtracting or adding the calculated rate of change level from a previously determined level of charge remaining on the re-chargeable battery. A wireless communication unit and is also described. This provides a significant improvement in accuracy, as knowing accurate charge remaining in a battery allows a user to know how much talk time or gaming time remains available in the phone. Furthermore, it also provides an ability to compensate for temperature or load within the phone.
