With the deepening of the construction of socialist new rural areas and beautiful villages, solar street lights have become ubiquitous as the preferred lighting equipment. Not only are solar street lights energy-saving and environmentally friendly, but they also do not incur electricity costs, making them popular among the public. In the past, many solar street lights used lead-acid batteries, but now, most of them have switched to lithium batteries. What are the benefits of using lithium batteries in solar street lights? Regarding this question, let us introduce the topic.
Safety
Lithium batteries are very safe as they belong to the category of dry batteries. Compared to ordinary storage batteries, they are used more safely and stably. This is related to the element lithium, which is an inert element that does not easily change its properties, ensuring stability.
Intelligence
During use, it is observed that solar street lights can turn on or off at fixed times. In continuous cloudy weather, the brightness of the lights varies, and some even have different brightness levels during the first and second halves of the night. This is the result of the combined work of controllers and lithium batteries, making them very intelligent. They can automatically control the on/off times and adjust brightness automatically. Additionally, street lights can be turned off with a remote control for energy-saving purposes. Depending on the different seasons and varying daylight durations, the on and off times can also be adjusted, showcasing high intelligence.
Controllability
Lithium batteries inherently have controllability and zero pollution characteristics, causing no pollutants during use. Many street light failures are not due to the light source but relate to the battery. Lithium batteries can manage their energy storage and output without waste, thus extending their lifespan. Lithium batteries typically have a lifespan of seven to eight years.
Environmental Protection and Energy Saving
Lithium battery street lights generally come equipped with solar energy functions. They generate electricity from solar power, storing excess energy in lithium batteries. Even in continuous cloudy weather, they do not stop illuminating, fully utilizing natural solar resources for power without generating any consumables. This not only protects the environment and saves energy but also extends the lifespan of the street lights.
Lightweight
Being dry batteries, lithium batteries are relatively light in weight. Despite being lightweight, they have substantial energy storage capacity, making them adequate for regular street light operation.
High Storage Capacity
They possess a high energy density that is unmatched by other batteries.
Low Self-Discharge Rate
It is known that batteries typically have a self-discharge rate, and lithium batteries excel in this aspect, with less than 1% self-discharge rate in a month.
Strong Adaptability to Temperature Variations
Lithium batteries have strong adaptability to temperature variations, functioning within environments from -20°C to 60°C. With proper processing, they can work in environments as cold as -45°C, so there is no need to worry about using solar street lights in very cold regions.
The benefits of using lithium batteries in solar street lights have been shared here. The advancement of technology has promoted the development of the solar street light industry. The application of lithium batteries in solar street lights represents a revolutionary change for the solar street light industry, significantly reducing costs and enhancing the lifespan of solar street lights.
