1, durability/battery life: lead-acid battery life is generally about 2 years, and lithium battery is more durable, life is 4-5 years; And the effective charge and discharge cycle of lead-acid battery is generally within 300 times, while the effective charge and discharge cycle of lithium battery is more than 500 times.
2, volume mass/easy to operate: compare lithium battery only 2.5/3kg light body, generally the same capacity lead-acid battery weight about 16/30kg; Not only is the battery heavier, but it's also bulkier; Compared with the laborious twists and turns of the lead-acid trolley, the lithium trolley can be dismounted and transported more conveniently by riding.
3, the market price/performance ratio: now the market for mainstream lead-acid battery is about 450 yuan, and the price of lithium battery is more expensive about 1000 yuan; The price of the two types of battery is different, and the price of the corresponding electric car is also very different. Together, lithium battery life is also 1 year longer than lead acid, can *2 years.
4. Range/battery capacity: The same battery is 48V. Under full charge, the range of lead-acid/lithium battery electric vehicles is almost the same, depending on the speed, size of the motor and other factors. Of course, lead-acid batteries have slightly more capacity than lithium-ion batteries.
5, travel kilometers: the same is 48V battery, in the case of full charge, lead-acid battery and lithium battery electric car can travel 30-40 kilometers. The speed depends largely on the size of the motor used.
6, the price, quality period: now on the market is 48V mainstream battery, if replaced, lead acid battery 450 yuan, quality period for 1 year lithium battery price is relatively expensive, need 1000 yuan or so, but the quality period for two years.
7, ring * : in 2012, the state published the "lead battery occupation access conditions" in the future, lead acid occupation after restructuring and integration, most manufacturers have used internalized into cadmium free arsenic-free green production, more ring *, more energy saving, only in the recovery process temporary, if the method is not appropriate may form pollution; Lithium battery in the production, recovery, relatively more green ring *.
8. Trend: With the introduction of the new national standard of electric bicycle, lightweight battery and high energy density have become the inevitable trend of power energy. Lithium battery is undoubtedly the best choice and also the development trend.
Looking at the above eight differences, we believe we will find that, compared with lead-acid batteries are not easy to operate, bulky and not durable, lithium battery electric vehicles seem to have advantages. Of course, lead-acid electric cars are cheaper.
Lead-acid batteries have higher uniform voltage and higher energy density than lithium batteries. In other words, lithium batteries have more capacity for batteries of equal size and size. In addition, lithium batteries are relatively light, easy to carry, and relatively long life. In addition, lithium batteries are more adaptable to high and low temperatures, less affected by temperature, and more green ring *.
Of course, lithium battery also has three defects, if the selection of inferior battery, its safety and stability is relatively poor, if the operation is not proper, it is easy to occur the risk of spontaneous combustion, of course, select some safe products, the possibility of spontaneous combustion is very small. In addition, the lithium battery can not be large current discharge and production requirements of high conditions, higher cost. Compared with lithium batteries, lead-acid batteries are relatively cheap and more acceptable to the masses. In addition, lead acid batteries have high rate discharge performance. * Importantly, lead-acid batteries have a higher recovery price than lithium-ion batteries.
However, lead-acid batteries have their drawbacks, such as heavy metals that cause pollution. Lead-acid batteries have lower energy density than lithium-ion batteries. And they don't last as long as lithium-ion batteries.
Lead-acid batteries or lithium batteries are good for electric vehicles
In addition to the electric vehicle brand is our focus, electric vehicle battery quality is also our note points. Electric car battery manufacturing occupation can be said to be a very market, in addition to the lead acid battery is now used more, lithium battery has also moved into our days. Lead-acid batteries and lithium-ion batteries are common batteries used in electric vehicles. They have their own strengths and weaknesses.
Of course, from a safety point of view, lithium batteries are slightly worse than lead-acid batteries, so be sure to choose a safe product. If we charge it too much, it may spontaneously ignite. And if lithium batteries are used out, they cannot be recovered like lead-acid batteries, and the price is much more expensive than lead-acid batteries. Lead-acid batteries and lithium batteries have their own advantages, can not be said to be good who is bad, lead-acid batteries and lithium batteries how we should choose, but also need to see their own actual situation.
