For solar street lights, the most precious is the battery's power. On rainy days, the charging efficiency of street lights will be affected to some extent, thus the amount of electricity charged will be relatively small. What’s worse is that in some area, It will rain for several days without any interruption, which is a challenge to solar street lamps as to discharge time. In order to achieve the optimal balance of brightness and discharge time under the premise of the same configuration, a powerful software algorithm is needed to realize intelligent power adjustment technology.
The charge and discharge characteristics of the lithium iron phosphate battery itself make it difficult to realize the intelligent power technology. Many integrated solar street lamp manufacturers lack technology. In order to meet the customer's discharge time requirements, they choose to simply adjust the lamp brightness to a low level when the voltage is lower than a certain value. We have to say it is a very stupid strategy. Although the discharge time will be prolonged, the brightness is very low, it is difficult to achieve the effect of illumination. Now you may wonder our technical solution to the pain point. How can we ensure that the discharge time is longer under the premise of ensuring a certain brightness?
To answer this question, we have to remind you of our intelligent power technology, which is one of the core technologies of Road Smart solar street lighting products. The laboratory test results show that the discharge time is extended by at least 50% while our solar street lights keep providing a relative high brightness lighting environment. Road Smart intelligent power technology is sampled by hardware in real time. The software refers to various types of sampling data and uses differential gradient algorithm to reasonably plan the nightly discharge power based on local weather. This technology not only extends the discharge time but also ensure the brightness of solar street lights. A perfect balance of brightness and discharge time is achieved.
