Battery charger and method for communicating battery pack charging status information
First Claim
1. A method for communicating battery pack charging status information of a battery pack from a battery charger to an electronic device when the battery charger and the electronic device are both coupled to the battery pack, the method comprising:
- reading an authenticity battery pack identifier and charging status information provided by the battery pack to the battery charger, the battery charger and the electronic device being separate devices that are each able to be individually decoupled from the battery pack;
transmitting in a status message over a wireless link the authenticity battery pack identifier and charging status information from the battery charger to the electronic device; and
processing, by the electronic device, the charging status information when the authenticity battery pack identifier matches a currently coupled battery pack identifier stored in the electronic device, the currently coupled battery pack identifier identifying the battery pack that is coupled to the electronic device.

Abstract
A battery charger and method for communicating battery pack charging status information of a battery pack coupled to both the battery charger and an electronic device such as a radio is presented. An authenticity battery pack identifier and battery status information provided by the battery pack to the battery charger is read. The authenticity battery pack identifier and charging status information is transmitted over a wireless link from the battery charger to the radio. The charging status information is then processed by the radio when the authenticity battery pack identifier matches a currently coupled battery pack identifier stored on the radio. The currently coupled battery pack identifier identifies the battery pack that is coupled to the radio.
