BATTERY CHARGER COMMUNICATION SYSTEM

摘要

The present invention provides a method (350) comprising: (i) receiving, at a processing device (310), charge data (120) from a charging unit (200) via a network (110), the charging unit including a charger (210) and the charge data including a charge capacity indicating an amount of charge delivered to a battery (202) during a most recent charging session and a device (20) usage time indicating an amount of time that the battery was off the charger during a period preceding the most recent charging session; (ii) determining, at the processing device, an average discharge rate of the battery based on previously received charge data corresponding to the battery; (iii) determining, at the processing device, an estimated state of charge (130) of the battery based on the average discharge rate; and (iv) providing, at the processing device, the estimated state of charge to a user device (400) for display.

1. A method (350) comprising:
receiving, at a processing device (310), charge data (120) from a charging unit (200) via a network (110), the charging unit (200) including a charger (210) and the charge data (120) including a charge capacity indicating an amount of charge delivered to a battery (202) during a most recent charging session and a device (20) usage time indicating an amount of time that the battery (202) was off the charger (210) during a period preceding the most recent charging session; determining, by the processing device (310), an average discharge rate of the battery (202) based on previously received charge data (120) corresponding to the battery (202); determining, by the processing device (310), an estimated state of charge (130) of the battery (202) based on the average discharge rate and a current device (20) usage time, the current device (20) usage time corresponding to a period after the most recent charging session; and providing, by the processing device (310), the estimated state of charge (130) to a user device (400) for display.
