How to extend the life of street light using solar energy?

  Among all the accessories of street light using solar energy, the battery is a very important component, which is the function of energy storage for street light using solar energy. How long it takes for the street light using solar energy you purchase depends on it, so we usually do battery maintenance.

     Firstly,street light using solar energy need to avoid battery overcharge.The service life of the street light using solar energy’s battery is related to the heat accumulation of the internal product of the battery, and the heat source in the battery is derived from the loss of the internal chemical reaction of the battery, and can be seen as the product of the charging voltage and the charging current. Thermal runaway can cause the battery to lose water, the shell "bulk belly" and other conditions, which can cause the battery to be scrapped in very serious cases. So the battery should prevent overcharging, how to prevent overcharging? It is necessary to set the combined power supply in strict accordance with the instructions given by the manufacturer. 

   Secondly,street light using solar energy need to prevent the battery from being insufficiently charged.If the battery is not fully charged, it may be caused by the charging voltage setting being too low or too low, or there may be a problem with the rack system.

   Thirdly,street light using solar energy need to prevent battery over-discharge.Excessive battery discharge is related to the number of battery design charge and discharge cycles (lifetime). For example, when the depth of discharge is 5%, the number of cycles is 10,000, and when the depth of discharge is 50%, the number of cycles is only 1000. Excessive discharge will cause the battery to no longer be activated to the best state, or even scrapped. The discharge time and the termination voltage are different at different discharge rates, and the effective capacity released is also different and is affected by the ambient temperature.

       Forth, street light using solar energy need to control the ambient temperature of the battery.If the temperature of the battery rises, the electrolyte will accelerate the activity, the internal resistance of the battery will decrease, the increase of the floating charge flow will lead to the corrosion of the conductive components, and the life will be reduced. Conversely, the electrolyte activity will be weakened and the internal resistance of the battery will increase. The discharge capacity to the load is reduced.

         Fifth,street light using solar energy need to replace the faulty battery in time.We can use a variety of methods to determine whether it has become ill, such as its capacity test alone, or online testing its internal resistance. The key is to replace the faulty battery in time, which is very important for the availability of the solar streetlight battery pack and even the entire life cycle.
