Abstract
Official abstract text for this publication.
Disclosed are charging control methods for a rechargeable battery and portable computers. The charging control method includes acquiring a control parameter for a charge current of the rechargeable battery; modifying, based on the control parameter, the charge current from a first charge current to a second charge current less than the first charge current; and charging the rechargeable battery with the second charge current. Compared with conventional methods of charging the battery always with the maximal charge current, the present disclosure can improve the battery's lifetime.
First claim
Opening claim text (preview).
What is claimed is: 1. A charging control method, comprising: acquiring a decision parameter for a charge mode; deciding, based on the decision parameter, whether a first charge mode or a second charge mode is adopted in a current charging operation; and charging a rechargeable battery with a first charge voltage in the first charge mode, and charging the rechargeable battery with a second charge voltage larger than the first charge voltage in the second charge mode; wherein…
