How To Maintain Solar Energy Street Light Battery?

Solar energy street lights are widely installed in streets, roads, highways. Using solar power, the solar lighting solution is economical and environmentally friendly. With the vigorous development of new rural construction, the sales of solar energy street lights are rising rapidly, and many rural areas regard solar street lights as an important choice for outdoor lighting. However, some people still worry about its service life and think that it is a new product with immature technology and short service life. Even if the solar energy street light manufacturer provides a three-year warranty, many people still have concerns about it. The solar energy street light is composed of various parts, and none of them are indispensable. It consists of light source, rechargeable battery, solar panel, intelligent controller, light pole, etc. Among them, the performance of the battery directly affects the life of the entire street lamp, and high-quality batteries have a longer service life than ordinary batteries. In daily use, we should maintain the battery to extend the service life of the street light.

1. Control the ambient temperature

Whether the ambient temperature is too high or too low, it will affect the capacity of the battery and shorten its service life. First of all, in terms of battery selection, it is best to choose lithium batteries rather than gel batteries. Lithium batteries are highly adaptable to high and low temperatures and can be used in an environment of -20℃-60℃. Moreover, it is light in weight, has a long service life, and has a high storage energy density. If the battery is buried underground, it should be buried a little deeper, at least 40 cm. On the one hand, it can reduce the influence of temperature on the battery. On the other hand, it can also prevent being flooded and avoid water ingress into the battery.

2. Replace the faulty battery in time

If the battery is severely damaged and cannot be used, the battery needs to be replaced in time. Generally, you can find the original manufacturer of the street light to buy the corresponding accessories, because the street light is composed of many parts, and each part will affect each other. The battery to be replaced needs to be matched with the controller and solar panel.

3. Prevent the battery from overcharging and overdischarging

In the application of solar energy street lights, care should be taken to control the overcharge and overdischarge of the battery. The so-called overcharge control is to disconnect the charging circuit in time when the battery is overcharged. The over-discharge control is to disconnect the discharge circuit in time when the battery is in the over-discharged state. This is done to protect the battery and prolong its service life. Overcharge means that the charging current of the battery is greater than the current required by the battery, and the excess amount is the amount of overcharge. The overcharged power will be converted into heat to increase the temperature of the battery and easily cause the battery to deform. On the contrary, if the battery is often under-charged, the battery will not be charged after a period of time, and the capacity will rapidly decay. The deeper the over-discharge depth, the shorter the number of charge-discharge cycles, that is, the shorter the service life. Over-discharge will increase the internal pressure of the battery, causing the reversibility of the positive and negative active materials to be destroyed, and the battery capacity will also rapidly decay. Therefore, both overcharge and overdischarge will have a great impact on the battery. Therefore, it is necessary to rationally design the capacity of the battery and equip it with a suitable controller.

4. Prevent rainwater from entering

The outer packaging of the battery should be tight enough to prevent rainwater from entering. The battery is very afraid of water. Although it is said that waterproof measures have been made on the outer layer of the battery, in order to better play a waterproof role, it is necessary to cover the surrounding with cement to further strengthen the waterproof measures. In some constructions, waterproof battery boxes are installed for waterproofing.

The above is about the maintenance method of solar road lamp battery. By doing the above points, we can extend the service life of the battery. The specific service life still depends on the quality of the battery itself. EXC solar energy street lights use the most cost-effective lithium iron phosphate battery on the market. The cycle charge and discharge times are more than 2000 times, with high safety, high temperature resistance and longer battery life. In addition to batteries, the quality of the light source and solar panels is also very significant. If you need to configure a suitable solar energy street light, please consult us!
