1, durability / battery life: lead-acid battery life is generally about 2 years, while lithium batteries are more durable, life span of more than 4-5 years; and lead-acid battery cycle fully charged and discharged generally within 300 times, while lithium batteries are fully charged and discharged cycle times more than 500 times.
2, volume and quality / ease of operation: compared to lithium batteries only 2.5/3 kg of light body, generally the same capacity lead-acid batteries weigh about 16/30 kg; not only the battery quality is larger, the volume is also large; compared to the lead-acid car strenuous twisting and turning, lithium car removable design, riding and handling more convenient.
3, the market price / cost performance: now the main stream of commercially available lead-acid batteries for about 450 yuan, while lithium batteries are more expensive for about 1000 yuan; two types of battery prices are different, the corresponding electric car selling price also differs greatly. Together, the lithium battery warranty period is also 1 year longer than the lead-acid, can be guaranteed for 2 years.
4, range / battery capacity: the same 48V battery, full charge, lead-acid / lithium battery electric car range are similar, depending on speed, motor size and other factors. Of course, the battery capacity, lead-acid batteries will be slightly larger than lithium batteries.
5、Miles traveled: the same 48V battery, in the case of fully charged, lead-acid battery and lithium battery electric car can travel 30-40 km. The speed mainly depends on the size of the motor used.
6, price, warranty: the main stream battery on the market is 48V, if replaced, lead-acid battery 450 yuan, warranty period of one year lithium battery price is relatively expensive, need about 1000 yuan, but the warranty period of two years.
7, environmental protection: in 2012 the state announced the "lead battery industry access conditions" in the future, the lead-acid industry through restructuring and integration, most manufacturers have adopted internalization into a cadmium-free arsenic-free green production, more environmentally friendly, more energy efficient, only in the recovery process, if the method is not appropriate may form pollution; lithium batteries in production, recovery, relatively more green and environmentally friendly.
8, the trend: with the introduction of the new national standard for electric bicycles, battery lightweight, high energy density has become the inevitable trend of power energy, lithium battery is undoubtedly the best choice, but also the development trend.
See the above 8 points of difference, I believe we will find that, compared to the lead-acid battery is not easy to operate, bulky and not durable, lithium battery electric car seems to have more advantages. Of course, the price of lead-acid battery electric car is cheaper.
Compared with lead-acid battery, lithium battery has higher uniform voltage and high energy density, in other words, the battery of equal size, lithium battery capacity is more. In addition, lithium batteries are relatively light, easy to carry, and the life expectancy is relatively much longer. In addition, lithium batteries are more adaptable to high and low temperatures, less affected by temperature factors, and more green.
Of course, lithium batteries also have three defects, if the selection of poor quality batteries, their safety and stability is relatively poor, if not properly operated, it is easy to occur the risk of spontaneous combustion, of course, the selection of safe and guaranteed products, the possibility of spontaneous combustion is still negligible. In addition, lithium batteries can not be discharged at high currents and high production requirements, higher costs. Compared with lithium batteries, the price of lead-acid batteries is relatively cheap, the masses are more acceptable. In addition, the lead-acid battery has better performance in high rate discharge. The most important thing is that lead-acid batteries have higher recovery price than lithium batteries.
However, lead-acid batteries also have their own defects, such as heavy metals are prone to environmental pollution; compared with lithium batteries, lead-acid batteries have a lower energy density; and their use life is not as long as lithium batteries.
The difference and advantages and defects between lithium battery electric car and lead-acid electric car
Electric car choose lead-acid battery or lithium battery is good
In addition to the brand of the electric car is our concern, the quality of the electric car battery is also our attention point. The electric car battery manufacturing profession can be said to be very marketable, now in addition to the lead-acid batteries used more, lithium batteries also moved into our days. Lead-acid batteries and lithium batteries are commonly used in our electric vehicles, they have their own strengths and weaknesses.
Of course, from the point of view of safety, lithium batteries are slightly worse than lead-acid batteries, so be sure to pick a safe and guaranteed product. If we overcharge the head, then it may spontaneously combust. And if the lithium battery is used up, it can not be used again, like lead-acid batteries, and the price is much more expensive than lead-acid batteries. Lead-acid batteries and lithium batteries have their own strengths, can not absolutely say who is good who is worse, lead-acid batteries and lithium batteries we should choose, but also need to look at their actual situation.
