Battery type selection

　　Battery type selection

　　 There are many types of batteries. At present, wind power is one of the commonly used lead-acid batteries. After the battery is filled with liquid, it can be used for 30 minutes at a temperature of 5°C without the first charge. For remote areas where wind turbines have just been installed, as well as areas without initial charging conditions, immediate use of electricity is very good. The battery has disadvantages such as large volume, heavy weight, and inconvenient transportation. The aluminum-acid batteries sold on the market are batteries for automobile starting. Under the charging and discharging operation conditions of wind power generation, the plate structure and manufacturing characteristics of the battery are not suitable, and the service life is short, generally only about 2 to 3 years. In large-capacity wind turbines, fixed acid-proof and explosion-proof lead-acid batteries should be used, which have large capacity, small hydraulic specific gravity (about 1.21 at 15°C), reduce corrosion to the pole plate and separator, extend the evaporation time and Advantages such as anti-leakage measures. Reduce emissions to the ground.

　　He said:'The battery is small. It is light in weight and has a service life of about 15 years. It is also used in a small amount in our area. Although the life of alkaline batteries is 5 times that of acid batteries, their price is more than 10 times higher than that of acid batteries. Economically, we think it is better to use lead-acid batteries in small wind power generation.
