Measure the performance of a solar studs on road also can from the following aspects.
1>Battery Life: An important factor in determining the life of a solar road stud is the life of the battery.The choice of battery is critical. There are two types of batteries on the market that can be referenced. One is to reduce the battery capacity to 50% after charging and discharging 500 times; the other is to reduce the battery capacity to 79% after 1000 times of charging and discharging. Battery life must not only be long enough, but also be able to work properly over a wide temperature range. The inside of the battery
is a chemical substance. If the temperature is too high or too low, the battery will not work. The battery operating temperature range of the solar road stud must meet the requirements of the actual use environment.
2>Electronic circuit: The design of the circuit board must follow the simple and effective design principle, not artificially complicated, because one more line has more than one possibility of failure. Electronic components must also be carefully selected, as any problem with one electronic component can make the
entire system paralyzed.
3>Welding: Welding must be reliable, because the solar studs on road are subject to the rolling and impact of the vehicle every day, and a little looseness of the solder joints will cause the line to loosen and fall off. Therefore, when selecting the welding torch and solder, we must select high-quality products to ensure that the solder joints are firm and reliable, and can work in a relatively "bad" environment for a long time.
4>Solar panels: Solar panels directly absorb solar energy and convert light energy into electrical energy. It can be said that it is the first link in the whole working system of solar road stud; its working efficiency directly determines the working efficiency of solar road stud. Monocrystalline silicon solar panels are now widely used because of the high photoelectric conversion rate of monocrystalline silicon solar panels, which is about 14%, which can convert solar energy into electrical energy to ensure maximum energy supply when solar road stud working.In addition, solar panels must be high-hardness, wear-resistan. The solar panels are subjected to the rolling wear of the wheels every day. If the strength is not enough, it is easy to grind and affect the conversion efficiency of the solar panels.
After being placed under standard test conditions for 8 hours, the rated capacity of the battery should meet the needs of solar stud on road for 72 hours of normal illumination; even if the solar illuminance is less than 1000LX, after the battery is charged for 8 hours, its rated capacity should meet the normal illumination of the solar road stud for 12 hours.
The environment in which solar road stud are used is complex and variable, and the temperature and humidity may be quite different. Canada's winter temperature is very low, Africa's summer temperature is very high, Japan's wet and rainy, these will affect the work normal of solar studs on road, so the design of solar road stud should fully consider the environmental adaptability.
The environmental adaptability of solar road stud is a comprehensive test of its mechanical and electrical properties, involving structural design, electronic device performance and other aspects, including its production process. This also requires that all aspects of the work must be done to ensure that the solar road stud have better environmental adaptability.
