Electric vehicles have been developed for more than twenty years, convenient and fast and loved by users, with the improvement of battery technology, the range of electric vehicles is getting farther and farther, from the earlier lead-acid battery, to the more lightweight lithium battery, people's choice is getting more and more, although we all know that lithium battery has higher energy density, but the durability and safety of lead-acid battery is better than lithium battery, in the end, how should we choose Electric car battery type?
Which is better: lithium battery or lead-acid battery for electric vehicles?
With the newer iterations of electric energy vehicle battery technology, the development of lithium batteries has a great tendency to rise from the saffron double stick to the boss of the association. However, it is only rising. Limited by their own performance, cost performance and other reasons want to replace the status of the lead-acid battery big brother still has a long way to go, and the big brother lead-acid battery is also constantly doing self-breakthrough.
Today's weather is good, by the old line (accidentally leak) to take you all to understand the battery society inside the saffron double stick (lithium batteries) and the society boss (lead-acid batteries) of the family kung fu it, recently Jiangshan cloudy and rainy, all of you examinations of the work of waiting for the results do not forget to go home to collect clothes.
So let's start with the lead-acid batteries.
The ancestral mastery of lead-acid batteries
1、Golden Bell Iron Cloth Shirt (hard!) The lead-acid boss has been in line with his strong let him be strong, the breeze caresses the hillock. He is horizontal, let him be horizontal, the moon shines on the river as the principle. Lead-acid battery is good to live, you can drop and beat, a little repair, you can continue to use.
2、Cabbage price (cheap!) The reason why the lead boss was able to dominate the battery society for many years and sit in the boss position is all because of this reason! Cheap, in addition to cheap or cheap.
3, back to recast (recyclable reverse repair) lead-acid batteries come with recyclable skills, after the use of bad can go to the electric car store to exchange the old for a new, make up the difference can be replaced by a new set of batteries, to minimize the loss, the user is a considerable benefit.
Since we are talking about the Jedi, let's also look at the disadvantages of lead-acid batteries: large volume and weight, limited battery capacity, short life, lead-acid batteries are generally within 400 times of deep charging and discharging, memory, life expectancy in about two years.
Ancestral mastery of lithium batteries
1, ancestral lightness (light weight, small size) from childhood lightness of the lithium battery with the same capacity on the market compared to lead-acid batteries, lithium battery volume is 2/3 of the volume of lead-acid batteries, the weight is about 1/3 of the weight of lead-acid batteries. the same volume of lithium batteries than the capacity of lead-acid batteries to high, the reduction in weight makes the electric vehicle range increased by about 10%.
2, health and durability (life increase) lithium battery deep health, lithium battery average life is about 4 years, about 1.5 times higher than the life of lead-acid batteries, charging and discharging more than 500 times, the battery use no memory, strong shock resistance.
3, ancestral qigong exhalation method (overcharge resistance, good performance of charge and discharge resistance) lithium batteries from childhood to open the eight channels of the Qi meridians, so that under normal temperature, lithium batteries can be continuously charged for 48 hours without accidents such as battery expansion and leakage rupture, the capacity is maintained at more than 95%. And under the special charger, it can be charged and discharged quickly.
Although the benefits of lithium batteries, but its disadvantages are also more obvious
The production cost of lithium batteries is high, the production equipment is expensive labor costs account for about 40% of the production cost, the price is about three times the lead-acid batteries. Its three times the price does not bring the cost performance is not high, rather than give people the feeling of flashy, and lithium batteries can not be recycled, with bad can only be thrown away, or find a place to bury, after a few thousand years, descendants dig out is an antique.
The most important problem is the existence of lithium battery fire and explosion safety hazards, especially in the case of consumers unknowingly deceived by the unscrupulous businessmen led to the purchase of poor-quality lithium batteries, in electric vehicles such as sealing conditions are not too good, easy to wet lead to poor contact and other reasons that may lead to the existence of safety hazards. However, the technical performance of lithium batteries is also improving, is also using high-security materials, the existence of safety hazards may be just a small needless worry, perhaps not long is the world of lithium batteries may also say it.
