Problems solved by technology

[0017] Because of the characteristics of this kind of battery, it is very difficult for the battery to maintain a constant full charge state. In addition, due to the influence of the battery's own discharge, it is very difficult to maintain not only a near full charge state, but also a complete full charge state.
[0018] As a result, it is very difficult for the batteries used in conventional notebook computers to maintain a fully charged state, thus, the user will encounter the situation that the battery cannot be used in a fully charged state, which shortens the service time of the battery and causes damage to the battery at the same time.

Embodiment Construction

[0038] The battery charging control device and its operation process of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] The present invention can be divided into the first charging control mode that controls charging according to the charging requirements of the battery; the second charging control mode that controls charging before the battery is fully charged according to the user's requirements even if there is no charging requirement from the battery model.

[0040] In the above-mentioned first charging mode, the charging of the battery is controlled when the control unit inside the battery generates a charging request as in the past. At this time, the battery charging time, charging voltage, battery charging current, etc. are all based on the characteristic diagram shown in Figure 2.

[0041] The above-mentioned second charging control mode controls the charging of the battery according to the user's request w...

Abstract

This invention relates to a cell charge controller and its method for controlling charge of cells based on the needs of users, in which, the invention is equipped with a first charge control mode controlling charge of cells based on the needs of the cell and a second charge mode for forcing the charge of cells in terms of the needs of users, the operation of the two modes is based on the information of the cell and the second charge control mode controls the charge based on the set signals.

Description

technical field [0001] The invention relates to a battery charging control device and a method thereof. Background technique [0002] Portable terminals such as notebook computers and PDAs receive common AC power through an adapter, or receive necessary power from a battery. This kind of portable mobile terminal is mobile and portable, so its own weight, size and battery management are his life. [0003] The battery used in the above-mentioned portable terminal is a battery that can be recharged. Recently, the development of portable and wireless electronic products has been increasing. In order to achieve the miniaturization and weight reduction of these products, secondary batteries with high energy density are used. Batteries are especially important. In addition, as people's awareness of environmental protection continues to increase, so does the emphasis on environmentally friendly products. [0004] From this point of view, lithium-ion secondary batteries can meet t...
