Abstract
A battery pack (304) and battery charging system (300, 400) provides contactless dynamic battery parameter sensing. A proximity sensor (208) is located in the battery pack (304) to monitor battery parameter measurements taken by battery parameter sensors (206). These battery parameter measurements are transferred to a charger (302) or radio (404) through a wireless link established between an excitation circuit, proximity sensor, and reader. The dynamically measured battery parameter information allows a charger (302) or radio (404) to select or adapt a charging routine based on the battery measurements. The use of a proximity sensor (208) along with battery parameter sensors (206) allow for minimal interface contacts between the radio and charger as well as the radio and battery.
