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, then stores the electrical energy in batteries for nighttime lighting. A vehicle battery is a battery used in automobiles, primarily used to start the engine and power the vehicle's electronic equipment. So, can solar street lights use car batteries?
First of all, from the perspective of battery type, solar street lights generally use deep cycle batteries, while car batteries use starting batteries. A deep cycle battery is a battery that can be charged and discharged multiple times and is suitable for long-term power supply applications, while a starter battery is a battery that can provide immediate current.wearing for a short time and is suitable for instant feeding. high power demand scenarios such as starting a car. Therefore, in terms of battery type, vehicle batteries are not suitable as batteries for solar street lights.
Secondly, from the perspective of battery capacity, solar street lights need to be powered for a long time, so a larger capacity battery is needed to store enough electrical energy. The capacity of car batteries is relatively small and can generally only meet the short-term starting and power supply needs of the car. If vehicle batteries are used as batteries for solar street lights, the problem of insufficient capacity will lead to shortened lighting time at night and cannot meet actual needs.
In addition, there are also differentnces in charging methods for solar street lights and car batteries. Solar street lights convert solar energy into electrical energy using solar panels, then store it in batteries. Car batteries must be charged by running the car engine or by an external power source. These two charging methods are not compatible with the working principle of solar street lights, so vehicle batteries cannot be used directly to power solar street lights.
In summary, solar street lights cannot use car batteries. Due to differences in battery type, capacity and charging methods, vehicle batteries cannot meet the long-term power supply needs of solar street lights. Therefore, when you choose a battery for solar street lights,you should choose a suitable deep cycle battery to ensure stable power supply for night lighting.
Using automotive-grade power cells, the lithium battery life of solar street lights is more than 15 years.
In recent years, lithium batteries are no longer like they were in the beginning. There are only lithium batteries at the energy storage level. Battery life at energy storage level is only 3-8 years. The ternary battery on the market only has 200-300 cycles, which is similar to the lifespan of lead-acid battery, which is only 2-3 years. Energy storage level 32650 battery can last 4-5 years.
Nowadays, many car batteries are used step by step. Manufacturers of high-end, high-quality solar street lights directly use new car batteries to obtain the highest efficiency.rt lifespan of lithium batteries in solar street lights. A good ladder battery has over 1,000 cycles and a lifespan of over 10 years.
There are also current lithium-iron batteries with good low temperature resistance, such as BYD C20 batteries, which charge and discharge 70% at -20 degrees. Our factory has been using lithium battery solar cells in Xinjiang, Inner Mongolia and Qinghai for three winters without any after-sales service.
