Definition of solar bike
Solar bicycles are bicycles that convert solar energy directly into electrical energy and drive the motor. They are mainly composed of solar cells, DC motors, batteries and bicycles. The solar battery is the bicycle's generator. The battery stores the energy that the solar energy turns into. On the one hand, it provides a large starting current for starting the bicycle, and on the other hand, it is used for rainy days and nights.
Solar cell principle
Solar cells are a solid state device. It absorbs sunlight and converts light energy directly into electrical energy. It completely relies on its internal solid structure to complete this function. There are no moving parts, but it must be installed on a bicycle as the only energy source of the vehicle. It requires that solar cells provide 120 Watt power supply. The corresponding solar cell area is about 1.2 square meters. The large-area silicon solar cell uses integrated circuit technology to integrate N-type silicon and P-type silicon together with connecting wires on an optical glass substrate to form a 305 mm × 305 mm square solar cell. The operating power is 12 V and the output power is 5 Peak tile. Can be connected in series, in parallel to form a variety of power supplies.
6-inch calculation, the motor speed is 170 revolutions per minute. Because of the bulkiness of low-speed DC motors, it is difficult to use on bicycles. The Deceleration Method of High-speed Motors for Electric Bicycles in China in 1980s. The 24 V DC motor is produced at a speed of 3,500 rpm and the mechanical speed reducer is used to reduce the speed. It's still clunky on the bike. Recently, the development of advanced power technologies and people’s attention to energy, safety, and environmental protection have aroused people’s interest in the development of low-speed DC motors and the development of three-in-one electric wheels for motors, reducers, and clutches. Weighing only 3.2 kg. The power is 120 watts, 140 watts, 180 watts, and 190 watts, respectively. Various hub motors with voltages of 24 volts and 36 volts. There is a small hole on the outer edge of the hub, which can be connected to the rim by spokes. The hub motor is 80 mm wide and can be replaced directly with the front or rear axle of the bicycle.
Bicycle features
The speed of the solar bike is calibrated at 22 kilometers per hour. Calculated on a bicycle wheel diameter of 26 inches, the motor speed is 170 revolutions per minute. Because of the bulkiness of low-speed DC motors, it is difficult to use on bicycles. The Deceleration Method of High-speed Motors for Electric Bicycles in China in 1980s. The 24 V DC motor is produced at a speed of 3,500 rpm and the mechanical speed reducer is used to reduce the speed. It's still clunky on the bike. Recently, the development of advanced power technologies and people’s attention to energy, safety, and environmental protection have aroused people’s interest in the development of low-speed DC motors and the development of three-in-one electric wheels for “motors, reducers, and clutches†in China. Weighing only 3.2 kg. The power is 120 watts, 140 watts, 180 watts, and 190 watts, respectively. Various hub motors with voltages of 24 volts and 36 volts. There is a small hole on the outer edge of the hub, which can be connected to the rim by spokes. The hub motor is 80 mm wide and can be replaced directly with the front or rear axle of the bicycle.
Current defect
Electric bicycles are currently hindered by driving range, power, recharging capability and battery life. Traditional lead-acid batteries (including imported original maintenance-free batteries) can only be charged and discharged 400 times. If the battery is used for deep discharge, it will be charged after the battery capacity is used up. It can only be used 20 times and the battery will be completely disabled. This limits the development of electric bicycles. To this end, the U.S. Department of Energy and other joint ventures have invested US$260 million to establish the United States Modern Battery International Financial Group (USABA). Long-term development of "sodium-sulfur batteries," "nickel-hydrogen ion batteries," "lithium-polymer batteries," and "lithium-ion batteries."
Nowadays solar bicycles that can actually be put into use are all based on the "floating solar energy charging principle. They use NPS silicon solar cells and BEST fully sealed maintenance batteries to make up solar power. They reduce the discharge rate of batteries and reduce the deep discharge of batteries and the self-supplement of batteries. Discharge loss can increase the service life of the battery several times.
China's first solar bike
China's first solar bicycle Ningde came out and started mass production
At the first Fujian-Taiwan (Ningde) agricultural and sideline products trade fair and annual fair held on January 10 in Ningde, Fujian, the first solar bicycle in China will be unveiled. The person in charge of Fujian Hengjiu Energy Saving Technology Co., Ltd. disclosed to the reporter of the company here on the 7th that the solar bike produced by the company had already come out in Ningde, Fujian, and began mass production.
It is reported that this solar bike is only 9 kilograms in weight. Its style is very simple, the shape is like an ordinary folding bicycle, like a blue solar panel hanging on the front, can not see the battery; the key is a piece of plastic 3 cm in length and 1 cm in width, it is mounted on the front of the car On the button, the car can be started through induction.
According to reports, due to rely entirely on solar energy as a driving force, solar bicycles have many advantages such as small size, zero pollution, energy saving and environmental protection, and can reach speeds of up to 20 kilometers per hour on flat roads. The company has introduced "aerospace high technology" to make bikes "lightweight" in shape. At the same time, it will introduce solar energy technology into the field of bicycles.
Experiments have proved that the bicycle is easy to carry and fold, and it can be charged through a backup external power supply when it encounters rain, or using ankles. No matter where you are, you do not need to worry about the return being affected. Especially when you are in the wild, you can use a solar battery for computers, mobile phones, etc. Use for lighting, etc.
British Solar Bicycle
Britain invented a solar powered bicycle powered by sunlight. Its appearance does not look much different from that of an ordinary bicycle; however, it contains a canopy device that can accept solar energy. After the user picks up the pedals on the bicycle, the canopy converts the received sunlight into energy stored in the bicycle battery, which drives the bicycle by discharging the electronic engine at the rear wheel of the bicycle.
It is understood that this kind of bicycle has a top speed of 15 miles per hour. In addition, this type of solar bicycle can also reduce the resistance that the rider encounters when riding a bicycle uphill. According to the designer of the solar bicycle, Miljevik said: "The bicycle I designed is purely environmentally friendly and does not cause any damage to the ecological environment." Miljevik said that the bicycle's engine is in sunny weather and The bicycle can be charged without being driven; if the weather is not good, the driver can use AC to charge the battery.
This bike looks like an ordinary electric bike. There is a canopy on the outside of the bicycle to facilitate large areas of receiving sunlight. If you do not use a bicycle during the day, you can put it in the sun and charge it for use when it is fully charged.
At night, there is a small battery on the bike that can last for hours. In order to save energy, the on-board engine can be turned off while driving down a steep slope. In addition, in order to make it easier for the rider to drive the bicycle and make the rider feel comfortable, Miljevik has designed the handle on both sides of the seat instead of being placed in front of the ordinary bicycle. Because of the canopy, even when it is raining, you can ride in the rain with ease without fear of getting wet.
