Embodiment Construction

[0029] figure 1 A diagram illustrating the charge and discharge characteristics of a common rechargeable battery in a portable electronic device. The vertical axis in the figure represents the power stored in the battery, while the horizontal axis represents the length of time the battery has not been used. It can be seen from the curve in the figure that a fully charged battery will slowly discharge over time until the battery is exhausted. But it is worth noting that there is a low-voltage level 102 on the battery, and the rate of power loss in the battery will increase rapidly after the low-voltage level 102, so generally the battery will avoid using the area after the low-voltage level 102.

[0030] Therefore, the basic idea of ​​the present invention is to use the low-voltage level 102 to define the normal operation area of ​​the battery (that is, the area before the low-voltage level 102), and to place another battery before the low-voltage level 102 but close to the lo...

Abstract

The invention relates to the charging and maintenance method used to cell can charge. In the process, one slow time and one charging electric equal are set in advance. On the condition of the using time of the cell below the slow time, when the containing electric mete of the cell exceeds the charging standard, the cell cannot be charged, otherwise, the cell charges; on the condition of untapped time of the cell exceeding the slow time, when the containing electricity mete exceeds the charging standard, the cell discharges firstly, then the cell charges, otherwise, the cell should be charged directly.

Description

technical field [0001] The invention relates to a charging and maintenance program for a rechargeable battery, in particular to a charging and maintenance program for improving electric energy efficiency and prolonging battery life. Background technique [0002] With the development and progress of electronic and information product manufacturing technology, the integration and miniaturization of various electronic devices has quickly become a trend. Such changes have made many large and difficult-to-carry electronic devices evolve into portable electronic devices, such as desktop computers into notebook computers and home phones into mobile phones. In this case, the power supply of the electronic device can only be supplied by the battery. Therefore, the position of the battery device in the electronic device, especially in the portable electronic device is correspondingly important, and the improvement of the battery device is also paid more and more attention.
