A portable photovoltaic charging device for notebook computer

technical field

The utility model relates to a notebook charging device, in particular to a portable photovoltaic charging device for a notebook computer.

Background technique

With the rapid development of mobile Internet technology, mobile Internet devices play an important role in people's life and work. Through the continuous improvement of science and technology, mobile devices are becoming smaller and thinner. Mobile devices It is getting smaller and thinner, and the battery capacity cannot be further improved. Therefore, when these mobile Internet devices are used in different working environments, they often encounter problems such as insufficient power, and each charge All require a series of supporting equipment and power supply. As an inexhaustible renewable energy anytime, anywhere, solar energy can provide an ideal solution.

At present, the practical batteries for mobile devices such as notebook computers are mainly lithium batteries that can be charged and discharged many times. This kind of battery is not only lightweight, but also has a large capacity, and it does not have memory effect like nickel-metal hydride and nickel-cadmium batteries. Generally, the battery of a notebook computer is composed of three parts: the shell, the battery cell (battery pack), and the working circuit; the battery cell is generally composed of three series of two-parallel or other combined lithium battery packs, and the working circuit includes a charge and discharge controller and a protection circuit. . Its disadvantages are as follows:

1. The existing general household notebook computer can be used for 2-3 hours after a single charge, which is relatively short.

2. When charging the battery, a corresponding power adapter and connecting wire are required, which is inconvenient to carry and cannot be used uniformly.

3. When the battery power is exhausted, it is necessary to find a power point for charging.

4. The battery capacity will decrease with the increase of use time, so the use time of the computer will be shortened accordingly.

5. The battery capacity cannot meet the conditions of outdoor places without power supply.
