The DC port of the bicycle shared solar panel junction box is mainly used to connect the power generated by the solar cell to the external circuits. Through this DC port, energy from the solar cell module can be transmitted to the shared bicycle to provide power to the vehicle's electronic equipment.
Please note that what is provided here is for understanding and explanation only. Specific implementation and operation may require relevant professional knowledge and skills, as well as special attention to security and compliance. If you are using or considering using solar panels for shared bikes, it is recommended that you understand the applicable usage regulations and safety measures, and follow the relevant user guides and operating instructions.
Can we use the solar panels on second-hand shared bikes?
1. Solar panel + circuit + lithium battery + box, it's successful
Can the solar panels of second-hand shared bicycles be used?
1. p>2. Find a 5.5-6V solar panel and connect an IN5819 diode in series in the forward direction to directly charge the phone. The charging current depends on the output current of the solar panel you choose.
3. The specifications of the solar panel are 6V, 0.33A. Looking at the voltage, it is actually 18 small cells connected in series, each cell is 0.5V, so the open circuit voltage is of 9 V. Actual charging depends on the intensity range of sunlight. The voltage is 6.3-6.9V, just enough to charge the 6V battery, no charger needed.
4. It is cut from a large battery sheet of 15.6*15.6 square centimeters, because the size of the large battery sheet is about 3.5W, 6.6A is ccalculated in 0.33A increments, and each small battery sheet measures approximately 12 square centimeters.
5. Check the junction box behind the solar panel to see if there are rectifier diodes connected in series to the positive and negative wires inside. This prevents reverse charging. If not, add one.
Yes. Although solar panels are a very environmentally friendly piece of equipment and are suitable for used shared bikes, they need to be cleaned regularly as solar panels are equipment used outdoors and are therefore particularly easy to stain. The easiest place for solar panels to get dirty is on tempered glass, because tempered glass is the outermost protective film of solar panels. Be careful when cleaning tempered glass to avoid damaging the glass and causing unnecessary problems. An area where solar panels need cleaningis the panel, because when used outdoors, some mosquitoes often enter the panel, which will not only affect the use of the panel, but also damage the panel, so it should be cleaned in time. To clean the solar panel, you need to open the solar panel case, clean it and then install it. Also pay attention to frequently check whether there are bird droppings on the surface of the panel, as bird droppings will block sunlight and thus affect the efficiency of the panel.
