Precautions for maintenance of solar street lamp battery
The components of solar street lights are mainly composed of solar panels, batteries, light sources, etc. Because solar street lights are installed outdoors, maintenance is particularly important, especially for batteries.
The life of a battery depends on its depth of discharge. The greater the depth of discharge, the shorter the service life. When the load increases, the battery capacity should also increase. This may require the use of multiple batteries. The method of connecting the two batteries is as follows: connect the positive electrode to the positive electrode, and the negative electrode to the negative electrode of the battery. In this way, the power of the battery will be doubled, and the voltage is the same as the voltage of a battery. It is not advisable to connect batteries of different manufacturers or different ampere hours, because this will reduce the service life of the batteries.
Precautions for the maintenance of solar street lamp batteries:
The maintenance of batteries is mainly two preventions and one control
Two preventions: prevent over Discharge and prevent overcharge
Overdischarge: The deeper the depth of overdischarge, the shorter the number of charge and discharge cycles, that is, the shorter the service life, because overdischarge will increase the internal pressure of the battery, resulting in positive and negative The reversibility of the extremely active material is destroyed, the electrolyte is decomposed, the negative electrode lithium is deposited, and the resistance will increase. Even if it is charged, it can only be partially restored, and its capacity will be significantly attenuated, or even directly scrapped.
Overcharge: Overcharge means that the charging current of the battery is greater than the acceptable current of the battery. This overcharge will be converted into heat and increase the temperature of the battery, which is easy to cause for a long time. 'Thermal runaway' causes the capacity of the battery to drastically decrease and deform, and there are hidden dangers of explosion and combustion. Therefore, it is necessary to prevent the battery from overcharging, provide the charging voltage value in strict accordance with the regulations, and provide overcharge protection.
Whether the ambient temperature is too high or too low, it will also affect the capacity of the battery and shorten its service life. First of all, it is best to choose lithium batteries instead of gel batteries. The performance in terms of cold resistance and heat resistance is better.
If the battery is buried in the ground, it should be buried a little deeper, at least 40 cm. On the one hand, it can reduce the influence of temperature, on the other hand, it can also prevent being flooded and avoid water to the battery. influences.
Special attention must be paid to the maintenance of the battery of solar street lights. Over-discharge is not advisable. Similarly, over-charge is not acceptable. You must pay attention to the two preventions and one control of solar street light batteries.
