In recent years, road lighting, landscape lighting, smart lighting, plant lighting and other lighting fields have developed rapidly. The total amount of lighting energy consumption has gradually increased in the proportion of total electricity energy consumption. For total energy is scarce and the ecological environment is destroyed, vigorous developing solar lighting is extremely important. Green Tech super capacitor batteries are green energy storage device between traditional capacitors and batteries. Compared with batteries in the field of solar lighting, they are environment friendly, long charge and discharge cycle life (50000 times) , long service life 10 years,even short-circuit discharge without affecting its performance and life, wide operating temperature ( -30 ℃ to +60 ℃), long-term use without maintenance, high power density and easy recycling,etc.
Solar street light system has high value in road lighting. The solar LED street lamp system with Green Tech super capacitor batteries belong to composite energy systems. The power transmission in the system needs to be controlled online to ensure the normal operation of the system. Picture 1 shows the system structure of a solar LED street light with Green Tech super capacitor battery. As a core component, the controller manages the energy transmission between various components.
The solar LED street lamp system with Green Tech super capacitor battery is composed of photovoltaic battery array, so that the energy generated by the photovoltaic cell is first stored in the Green Tech super capacitor battery, and then the stored energy supply power to the battery through pulse or constant current at appropriate time.It can effectively improve the solar energy utilization rate and light comfort of the system.
