What are protection modes for durable luminaria smart solar street light?

      Durable luminaria smart solar street light use new environmentally friendly materials and rely on solar energy to convert electrical energy. It is widely used, from first- and second-tier cities to rural areas, and is widely recognized. From private gardens, city parks to communities and schools, it can be seen everywhere.Here are some of the protection modes for durable luminaria smart solar street light. The control unit in durable luminaria smart solar street light is the solar charge controller.The solar controller can control the durable luminaria smart solar street light to turn off during the day and turn on the night. At the same time, it has the function of overcharging and overdischarging of the battery. In addition,the durable luminaria smart solar street light controller can collect the working status and working information of the durable luminaria smart solar street light system to provide accurate and reliable basis for testing the system components.

       Firstly,direct charge protection point voltage for durable luminaria smart solar street light.Direct charge,also known as flash charge, is a fast charge. Normally, the battery is charged with a larger current and a relatively higher voltage when the battery voltage is relatively low, but there is a control point, also called a protection point.The direct charge protection point voltage is also the “overcharge protection point” voltage.When charging, the battery terminal voltage cannot be higher than this protection point, otherwise it will lead to overcharge and direct damage to the battery.   

         Secondly,equal charge control point voltage for durable luminaria smart solar street light.After the direct charge is completed, the battery is generally left to be charged and discharged by the controller for a period of time. The purpose is to let the internal voltage fall naturally.When it falls to the "recovery voltage" value, it will enter the state of equalization. Abbreviation for charging. In the process of equalizing, the charging time is not suitable for too long, generally it can be in a few minutes to ten minutes,if the charging time is set too long,it is not good. If it is for a small system equipped with a two-cell battery, the meaning of equalization is not great.Therefore, under normal circumstances, the durable luminaria smart solar street light controller is generally not set to charge,only two stages.

       Thirdly,floating charge control point voltage for durable luminaria smart solar street light.After the equalization is completed, the battery should also be left to stand for a period of time,so that the voltage at the battery end naturally falls. When it falls to the maintenance voltage point, it will enter the floating state. The floating state is equivalent to a small current charging. If the voltage inside the battery is low, it will be charged a little, and it will remain stable. It will be charged little by little to avoid the battery temperature rising continuously. It is good for the long-term use of the battery.

             Finally,over discharge protection termination voltage for durable luminaria smart solar street light.Battery discharge should not be lower than the international standard.Although each battery manufacturer has its own protection parameters,it is ultimately implemented in accordance with international standards.For the sake of safety, the 12V battery over-discharge protection point voltage is artificially added with 0.3V as the zero-drift correction of the temperature compensation or control circuit, so that the over-discharge protection point voltage of the 12V battery is 11.10V,then the over-discharge protection of the 24V durable luminaria smart solar street light system,the point voltage is 22.20V.
