Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] This embodiment is a photovoltaic battery-small battery power supply for portable equipment. The following is a description of each part:

[0026] This embodiment is composed of a controller, a photovoltaic cell, a small battery pack for power storage, a voltmeter, a switch and a protection circuit, etc.

[0027] Such as figure 1 and 2 shown. in,

[0028] The controller is composed of a microprocessor with low power consumption and a multi-channel analog-to-digital converter (ADC). In this embodiment, a PIC18L series single-chip microcomputer is used, and its input signal is a small battery pack voltage signal VM1, VM2, VM3 and VM4 , the output signals are switch signals DK-1~DK-2, DK+1~DK+2, CK+1~CK+4 and CK-1~CK-4.

[0029] Switch group, adopt low power consumption COMS switch in this embodiment, as figure 2 As shown, the swit...

Abstract

The invention relates to a method of photovoltaic cell - small cell which belongs to cell application technology field. The method includes: a controller detects small cell voltage in small cell group, when all small cell voltage are higher than full charge voltage, system enters into full charge state, the controller selects N-1 amount small cells in series for discharging, photovoltaic cell discharges indirectly; when the controller detects small cell voltage lower than full charge voltage, system enters into charging state, small cell with lowest voltage is selected as charging object of photovoltaic cell, other N-1 amount small cells discharge in series. Thereby, energy can be obtained from photovoltaic cell in various light intensity environment for example, strong light intensity, normal light intensity, weak light intensity, and charges to accumulator.

Description

technical field [0001] The invention belongs to the field of battery technology, in particular to a photovoltaic battery-small battery charging method. Background technique [0002] Since Pearson and others successfully prepared the first silicon solar cell in 1954, solar cells, as a new energy source, have far surpassed wind energy, water energy, geothermal energy, nuclear energy and other resources, and are expected to become the future power supply. The main pillar and will be widely used in all walks of life. Portable devices are also one of the very important application areas. For example, there were nearly 400 million mobile phone users in my country by the end of 2005. If most of these mobile phones use solar cells (also known as photovoltaic cells), it will have considerable economic benefits or social significance. [0003] Solar cells (also known as photovoltaic cells) currently in use mostly adopt the organizational structure of multiple cells connected in serie...
