Electric vehicles Battery refer to vehicles powered by "electric energy", saving fuel resources and avoiding exhaust pollution caused by "fuel" as power. However, our country attaches great importance to environmental protection, which coincides well with electric vehicles. Therefore, people in our country are more willing to choose electric vehicles for travelling.
"Electric power is recognised as a high-quality energy source. Nowadays, many aspects of life cannot be separated from "electricity". Household lights, televisions, computers, mobile phones and even today's high-speed trains are powered by electricity. When needed, the release of electricity is converted into "power" by the battery to drive. The battery is therefore a very important component of an electric vehicle. As a two-wheeled electric vehicle, due to its relatively low price, it is impossible to carry large functions and high-tech batteries such as three-way battery or blade battery as an electric vehicle. At present, lead-acid battery is the mainstream carrying battery, accounting for about 90% of the Electric Vehicle Battery market.
There are several reasons for choosing lead-acid batteries for electric vehicles
1, the cost, the reason why the cost in the first place, because it is not only a direct decision to choose an important factor, but also because the lead-acid battery and Lithium Battery in the cost of the big difference, the ordinary 60V20AH lead-acid battery is about 500 yuan, A group of 60V20AH lithium battery is about 1200 yuan to 1500 yuan, is two or three times the price of lead-acid battery, In addition, lead-acid batteries can be scrapped for about 200 yuan, while Lithium Batteries are worthless. Therefore, there is a big difference in cost, which is the main reason why lead-acid batteries are more popular.
2, maintenance, if the lead-acid battery encountered problems, can also be repaired through activation, hydration, technical repair and other means, but the lithium battery due to the complex process, maintenance success is too high, technical difficulty is greater, basically belongs to the "disposable" battery, used out can not be repaired, and most of the use of electric vehicles are low and middle income groups, They prefer lead-acid batteries, which can be maintained.
3, safety, since this year there have been a number of deflagging accidents related to electric vehicles, and after the investigation found that these deflagging batteries are lithium batteries, because of the different structure, lead-acid batteries do not have deflagging conditions, and lithium batteries are different, it reaches certain conditions will exist deflagging safety risks, and the unsafe label of lithium batteries let a lot of people have concerns about it.
4, practical, according to statistics, urban travel, there are 40% of people short-distance travel less than 3 kilometers, 70% of people short-distance less than 10 kilometers, the use of lead-acid battery can fully meet, and lithium battery is actually carried in motor more than 800W, battery voltage is greater than 72V electric vehicles, its advantages will be more prominent, and carried in low distribution electric vehicles, Its utility is not superior.
