Abstract
A battery charger method and apparatus are disclosed for providing detailed battery status and charging method information for a selected one of multiple batteries that are simultaneously coupled to the battery charger. The battery charger includes a controller. The controller selects one of the batteries to monitor and charge. The controller then starts a measurement cycle for the selected battery. During the measurement cycle, the controller determines current battery characteristics of the selected battery. The controller determines whether the selected battery is ready for charging by determining whether the battery characteristics of the selected battery are within a specified range. If the controller determines that the selected battery is ready for charging, the controller causes the battery charger to start charging the battery. If the controller determines that the selected battery is not ready for charging, the controller selects another battery to monitor and charge. Detailed information about the selected battery may be provided from the controller to a processor that is external to the controller.
