News about electric vehicle lithium battery explosions seems to be commonplace. Recently, there was another explosion of an electric vehicle's lithium battery in Beijing. It was learned that the lithium battery was for rent, and the user charged it at home to prevent it from being lost. is facing tens of millions in medical expenses, which is heartbreaking.

The numerous lithium battery explosion accidents that have occurred in succession have once again pushed lithium batteries to the forefront. One has to ask, in the era of new national standards, is it possible for lithium batteries to replace lead? How to ensure the stability and safety of lithium batteries? One voice believes that in view of the new national standards, light weight and other factors, it is imperative to replace lithium batteries with lead-acid batteries. Another oneix counters that although lithium batteries have natural advantages in terms of lightweight, their safety performance cannot be guaranteed. , lead-acid batteries could still be the norm in the coming years!
So, for electric vehicle users, how to choose between lead-acid batteries and lithium batteries? Let's hear what the drum master has to say!
Firstly, in terms of mass and volume, lead-acid batteries are larger and heavier than the lightweight body of lithium batteries, which weigh only 2.5/3 kg, lead-acid batteries lead of the same capacity. generally weigh around 16/30 kg. Although lead-acid batteries are currently beginning to be lightweight in design, lithium batteries can be flexibly disassembled and have better operability than lead-acid batteries.
Second, in terms of service life, the service life acThe life of lead-acid batteries is about 2 years, and the charge and discharge cycles are generally less than 300 times, while lithium batteries can be charged and discharged more. more than 500 times and the general lifespan is more than 3 years. There are also lithium battery manufacturers that offer a 3-year warranty.
Analyzing the cost-effectiveness of the two batteries, the current list price of lead-acid batteries in the market is around 450 yuan, while lithium batteries are relatively expensive. As lithium battery raw materials decline, some brands also mention the price of lithium lead batteries.
Finally, let's talk about cruising range, which is what electric vehicle users are most concerned about. It is also a 48V battery, when fully charged, the cruising range of battery electric vehicleslead-acid/lithium. is almost the same, depending on speed, factors such as motor size. Of course, in terms of battery capacity, lead-acid batteries will be slightly larger than lithium batteries.
According to the analysis of the above four aspects, lithium lead batteries are indistinguishable. Users who are more sensitive to price and practicality can choose lead-acid batteries. Those who care more about battery operation can choose lithium. batteries, which have better excellent performance. But there is a major problem in lithium batteries that urgently needs to be resolved: that of safety!
The safety problem of lithium batteries cannot be ignored. Any ordinary lithium battery brand will conduct strict testing on the products before putting them on the market. Therefore, consumers and retailers mustchoose ordinary lithium batteries. brand, secondly, good usage habits are necessary to protect it. Choice determines the future. Remember, don't be cheap when choosing a battery, life is precious!
