In recent years, the country pays more and more attention to the cause of green environmental protection and energy saving, the lithium battery electric car industry is heating up rapidly, and consumers are more and more recognized by the lithium battery electric car. Lithium battery can be charged and discharged up to 1200 times, about 3-5 years; lead-acid battery can be charged and discharged about 300 times, generally only 1-2 years.
The advantages of lithium battery for electric vehicles
1、Strong range, because the weight of lithium battery is only 30% of lead-acid battery, so at the same voltage and capacity, the lithium-ion battery has strong range.
2, low temperature discharge performance is good: lithium-ion battery can work normally at -25 degrees, its electric capacity can reach 70% of the nominal capacity, while the lead-acid battery at -10 degrees of the electric capacity of 50%, at -25 degrees not: can work normally.
3, lithium battery electric car charge retention capacity: will be fully charged lithium-ion battery pack, placed after two months, its electric capacity is greater than or equal to 80%, while the lead-acid battery placed for two months, only 40%-50% of the nominal capacity.
4, long cycle life: lithium battery charge and discharge at a rate of 1C, its cycle life is greater than or equal to 500 times, the 500th time the electric capacity, greater than the nominal copper beam 70%. And lead-acid batteries even with 0.5 discharge to 0.15C to charge, its cycle life is less than or equal to 350 times, the capacity is less than or equal to 60%.
5, high specific energy: because the volume of lithium-ion batteries is only 30% of lead-acid batteries, so when using the same space lithium-ion batteries have greater energy reserves than lead-acid batteries.
6, wide working temperature range: lithium batteries can work within -25 degrees to 55 degrees, while lead-acid batteries can only work within the range of 10 degrees to 40 degrees.
7、Short charging time: Because lithium battery has the characteristic of high current charging, the charging time is only 4-5 hours, while lead-acid battery takes 8 to 10 hours.
8, high current discharge does not affect the cycle life: lithium-ion batteries at 1.5C times the high current discharge, no impact on its cycle life. And lead-acid batteries in 1.5C times the rate of high current discharge. Its cycle life is only 30%-40% of the nominal cycle life.
9, can be discharged at high current: lithium-ion battery in 1C times the rate of high current discharge, its capacity is only 60% of the rated capacity.
10, high green performance: compared with lead-acid batteries have a large number of heavy metals harmful to human body and the environment lead, lithium batteries are highly environmentally friendly products.
Advantages of lithium battery electric car
●Lightweight body
According to incomplete statistics, people in big cities spend about 50 minutes on their way to work, so the demand for light transportation is very strong. Usually, the weight of lead-acid electric car is about 30 pounds, while lithium electric car can be reduced to 8 pounds at least.
Easy to park
For many young people nowadays, buying a car is easy and difficult, and for people in big cities, the annual parking fee for a car is a considerable expense. The lithium battery electric car does not need a parking space, and the lithium battery electric car is very easy to store because of the light battery and light frame.
●Environmental protection
Lithium battery electric car has another advantage, is environmentally friendly, but there is one thing we must understand lead storage electric car in the lead battery is polluting, of course, for pollution is controllable, as long as the battery can be recycled can. In contrast, the environmental advantages of lithium batteries are more obvious, completely pollution-free.
● Lithium-ionization of car enterprises
From the direction of the big development of electric vehicle enterprises in the past two years, they are more interested in the production of lithium battery electric vehicles, Emma, the new day have developed a variety of lithium electric vehicles.
Summary: With the launch of more electric cars by Tesla, BYD and other car manufacturers, lithium battery electric cars have entered our lives at once. In recent years, the lithium battery electric car is favored by people in big cities because it is lighter, and in the future the lithium battery electric car will become the popular choice of urban people.
