Description

Portable Smart Solar Power Supply

technical field

The utility model relates to the field of solar power generation, specifically a foldable, lightweight and portable intelligent solar power supply. the

Background technique

With the progress of the times, solar energy has come into life and is deeply valued by the public; at present, portable electronics generally need to be powered by batteries. After a period of use, the battery power will be exhausted. Charging, which brings great inconvenience to the long-term field work. the

Existing solar cell modules are generally sealed in a frame compatible with the solar cell array after the single solar cells are connected in series, and then the side receiving sunlight is covered with glass, and the other side is covered with a hard substrate or a soft substrate. Solar cell modules with hard substrates cannot be bent, and their mass and area are relatively large, so they are not easy to carry around. Thin-film solar cells can be folded and are light in weight, but the conversion rate of solar energy is not high; products with higher power also use lead-acid batteries, which are bulky and have no meaning of leisure and portability. the

The known Chinese patent announcement number CN 101860276 A discloses a "solar mobile power supply box", although the device is an integral design, but it lacks a protective effect on the solar battery in the folding mechanism, and there is no DC to AC AC output ; At the same time, the display of battery power is a light-emitting diode display, and there is no digital display of system work; in addition to solar power supply and intelligent conversion of mains power, this new model also designs a battery that can be replaced at any time on the back of the box. Tank when power is supplied or when service life is exceeded. the

Contents of the invention

The improved structure of the portable intelligent solar power supply includes: the front of the box is embedded with: voltmeter (3), ammeter (4), solar power supply mode indicator red light (5), mains power supply mode indicator green light (6), mains Mode start switch (7), solar power supply mode start switch (8), output socket (9), input socket (10), extension cord push-pull window (11), lock catch (12); a handle is embedded in the side wall of the box (13) and a USB power output socket (14); there is a switchable battery tank (15) on the back of the casing. The purpose of the present invention is to provide a portable intelligent solar power supply, which can store electricity only through solar energy, and then supply power to other equipment. When the power supply cannot be supplied or the service life is exceeded, the cover can be opened, the battery can be removed and a charged battery can be installed, and the charged lithium battery can be connected to the wire interface in the tank, so as to obtain the electric energy first. the

Its working principle is to convert the light energy of sunlight into electrical energy, store it in the battery, and boost it to AC110 volts or AC220 volts through the inverter power supply, and provide it to small electrical appliances with power less than the output power of the power box. Such as: electric fans, energy-saving lamps, incandescent lamps, laptop computers, mobile phones and other electrical appliances. Not only that, it can also be used in residential, office and other places as an emergency backup power supply. the

In the present invention, when the product is taken out, it can be directly connected to the mains port and directly powered by solar energy through the switching key. If the utility power is used for normal power supply, it can be charged, and it will jump to the backup power supply when the utility power is suddenly cut off. Make the flexible use of solar energy and mains power to achieve the purpose of energy saving. At the same time, when the battery is damaged and cannot supply power or exceeds its service life, there is a switchable battery tank on the back of the box, which can be replaced with a fully charged battery at any time, which can be used as a backup battery for emergency outdoor activities. Replace the battery with a good charge. the

Detailed ways

Referring to Figure 1, this embodiment adopts the following technical solutions: portable intelligent solar power supply, including: voltmeter (3), ammeter (4), solar power supply mode indicator red light (5), mains power supply mode indicator green light (6) , Mains mode start switch (7), solar power mode start switch (8), output socket (9), input socket (10), extension cord push-pull window (11), lock (12), handle (13) , a USB power output socket (14) and a switchable battery tank (15) on the back of the box body. Solar cell modules are composed of monocrystalline silicon solar panels and thin-film solar panels. The output power of the solar cell assembly can reach 200W. The solar cell components are connected by flexible cables. The solar components are divided into traditional monocrystalline silicon solar cells and thin-film solar cells. It is used as a hinge, and the thin-film solar panels are also glued with rubber sheets, which can be folded and unfolded at the same time. a. In sunny weather, open the box cover, unfold the folded thin-film solar cell, and turn on the solar power supply mode switch 8 to charge the battery. At this time, the red light of the charging indicator light starts to light up, and the charging starts. The electric board voltmeter begins to indicate the voltage generated by the electric board. When it reaches 15.6v, the charging ends. At this time, the charging controller protects the charging from overcharging, and no longer Battery charging. It can continue to supply power to electrical equipment during charging. The optimal load electrical power at this time is 70% of the rated output power. If it exceeds the rated output power, the battery will not be able to store energy due to the excessive load used at the same time. b. This new model also has the function of mains charging. When there is no sunlight, AC220V can be used to charge the power box. At this time, the socket 10 can be charged by plugging in the corresponding charging plug line. The charging method is automatic charging, and it will be automatically cut off when it is fully charged. Charging the power supply, no longer charging the battery box, the time is about 4-6 hours. C. This new model is equipped with a junction box in the box body, and a small retractable socket and a USB power output socket are embedded on the side wall of the box body, which can be used for power supply of small electrical appliances such as MP3/4, mobile phones, and digital cameras; and reverse The output power of the inverter can reach 1000W, which can meet the needs of field operations. the

Referring to Figure 2, the specific implementation method is when the solar energy is sufficient, the new model supplies power to the electrical appliances through the solar energy, and at the same time charges the battery and a switchable battery slot is designed on the back of the box, mainly when the lithium battery cannot work normally or When the battery power is insufficient, then open the cover, the battery is unloaded, the available lithium battery is put into the battery slot, and the battery wire is connected with the wire interface in the tank body, which is convenient for use. A sealing ring is arranged around the cover of the battery tank to prevent water from entering and causing electric leakage. the
