Batteries from electric vehicles can be used in solar street lights. The solar street light is a lighting device that uses solar energy to produce electricity. It converts solar energy into electrical energy via solar panels and stores electrical energy in batteries for nighttime lighting. The electric vehicle battery is also a device that stores electrical energy, so it can be used in solar street lights.
First of all, electric vehicle batteries have larger capacity and higher voltage, which can provide enough power for solar street lights. Solar street lights typically need to operate continuously for several hours at night, and the battery capacity of electric vehicles can meet this demand.
Second, electric vehicle batteries have a long lifespan and a nshadow of high cycles. Solar street lights require frequent charging and discharging, and after years of development and improvement, electric vehicle batteries have high service life and stability, which can meet the long-term use needs of solar street lights.
In addition, electric vehicle batteries also have high safety performance. Solar street lights are usually installed in outdoor environments and require high water, dust and earthquake resistance capabilities. Electric vehicle batteries have undergone strict safety testing and certification, have high safety performance, and can adapt to various harsh outdoor environments.
However, it should be noted that the lifespan and performance of electric vehicle batteries will gradually decrease with thetime. Therefore, when choosing an electric vehicle battery as the power source for solar street lights, you should consider its service life and maintenance costs to ensure the normal operation of solar street lights.
In summary, electric vehicle batteries can be used in solar street lights. It has large capacity and high voltage, which can provide enough electrical energy for solar street lights; it has a long service life and a high number of cycles, which can also meet the long-term use needs of solar street lights; has high safety performance, able to adapt to various outdoor environments. However, when choosing electric vehicle batteries as a power source for solar street lights, you need to consider their lifespan and maintenance costs.
Dessolar street lights! It must be on for more than 10 hours at night! What size battery panel is needed? There are also batteries
Solar street lights should be equipped with 92AH batteries and 18V70W panels.
Calculation process:
1. Daily power consumption of lamps:
20W*10H=200WH
Battery capacity:
200WH/12V*(3+1) days=67AH< /p>
Considering the efficiency and depth of discharge, the efficiency is calculated as 90% and the depth of discharge of the battery is calculated as 80%, then the battery capacity should be:
66/0.9/0.8=92AH
2. Calculation of solar panels
The sunshine time in the area is calculated based on 6 hours.
Battery discharge capacity each night=200WH/12V=16.7AH
Battery board charging current=1.5*16.7AH/6.5H =3.85A (1.5 is the coefficient, which is more common on rainy days. The higher the coefficient is higher, and vice versa, the smaller it is, usually between 1.3 and 2)
The power of the battery panel = 18 V * 3.85 A = 70 W.
18V70W solar panels can therefore be used.
Detailed informationAdvantages of solar street lights:
1. Easy installation: When installing solar street lights, there is no need to set up complicated wiring, just make a cement base and a battery pit, just fix it with galvanized bolts. There is no need to consume a lot of labor, material resources or financial resources, and the installation is simple. There is no need to install cables or "blast" the ground for construction, and there are no worries about power outages.
2. Low investment capital: Solar street lights are a one-time investment and will benefit in the long run. Thanks to simple wiring, there is no comaintenance costs or expensive electricity bills. The cost will be recovered in 6 to 7 years, and more than 1 million yuan in electricity and maintenance costs will be saved in 3 to 4 years.
3. Good safety performance: Since the solar street lights use a low voltage of 12-24V, the voltage is stable, the operation is reliable, and there is no safety risk. road administration services. There will be no accidents such as electric shock or fire.
4. Energy saving and environmental protection: Solar photoelectric conversion provides inexhaustible electric energy. No pollution, no noise, no radiation. Solar street lights can add new selling points to the development and promotion of noble ecological communities; they can sustainably reduce property management costs and reduce owners' public sharing costs.

The solar street light is a lighting device that uses solar energy to produce electricity. It can provide lighting function at night. In order to ensure that the solar street lights can last more than 10 hours, we must be equipped with appropriate sized panels and batteries.
First of all, we need to consider the energy requirements of solar street lights. Generally speaking, the power of solar street lights is between 10 watts and 100 watts. Suppose we choose a 50 watt solar street light, then we need to calculate the energy it consumes per hour.
The energy consumed by a 50 watt per hour solar street light is 50 watts times 1 hour, or 50 watt hours (Wh).
Next, we need to consider the power generation capacity of the solar panel. The electricity production capacity of solar panels depends on the intensitysity of solar radiation and panel efficiency. Generally speaking, the efficiency of solar panels is between 15% and 20%. Suppose we choose a solar panel with an efficiency of 18%, then we need to calculate the energy it generates per hour.
The energy generated by a solar panel per hour is equal to the intensity of solar radiation multiplied by the surface area of the panel multiplied by the efficiency. Assuming that the solar radiation intensity is 1,000 watts per square meter and the panel area is 1 square meter, the energy generated by the solar panel per hour is 1,000 watts times 1 square meter times 18 %, or 180 watt hours (Wh).
Finally, we need to take into account the battery capacity. The battery capacity depends on the energy generated by solar panels per hour and the energy consumed by solar street lights per hour. To ensure that the solar street light canrer more than 10 hours, we must choose a battery with a capacity greater than or equal to the energy consumption of the solar street light per hour multiplied by 10.
According to the previous calculation, the energy consumed by the street lights solar per hour is 50 watt hours (Wh), the capacity of the battery must therefore be greater than or equal to 50 watt hours multiplied by 10, or 500 watt hours (Wh).
In summary, in order to ensure that the solar street light can last more than 10 hours, we must be equipped with a solar panel with a power of 50 watts and a battery with a capacity of 500 watt hours. This way, solar street lights can provide continuous lighting at night.
