What is the reason why it is not recommended to replace lead-acid battery electric vehicles with lithium batteries?

First, the production cost of lithium batteries is high. The expensive production equipment and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. The price-performance ratio brought by its triple price is not high, and it is quite flashy, and the lithium battery is difficult to recycle, and the reuse rate is not high. Second, due to the small size of lithium batteries, there are multiple lithium batteries connected in series during assembly. During transportation and use, a certain solder joint may be disconnected or soldered. This is a common problem when connecting lithium batteries. Third, the high-current discharge characteristics of lithium batteries are shortcomings. Think about the frequent starts of congested roads, the battery life will be greatly reduced. Fourth, lithium batteries have potential safety hazards when they catch fire and explode. No one is willing to buy a timely bomb and put it under his body. Especially when consumers shop online for some inferior lithium batteries without their knowledge, the sealing conditions of electric vehicles are not very good, and they are prone to dampness leading to poor contact and other reasons that cause safety hazards. Some people may say that with the rapid development of lithium battery technology, this kind of problem will not occur, but no one can guarantee that this kind of problem will not occur. Fifth, compared with lead-acid batteries, lithium batteries have the same weight and volume, and the storage capacity of lithium batteries is generally about 3 times higher than that of lead-acid batteries. But for an electric vehicle as a means of transportation, its use is actually limited, because the endurance of many lead-acid batteries has also been greatly improved, which has reduced the gap between lithium batteries and lead-acid batteries. Sixth, if the lead-acid battery is replaced with a lithium battery, it must be considered that its voltage must remain the same as the original lead-acid battery. In addition, the charger must also be replaced with a dedicated lithium battery charger. Of course, there is a problem. Improper installation of the battery or quality problems may cause the controller to burn out. This is one of the reasons why the installation is not recommended. Seventh, in addition to the promulgation of the new national standard, the speed limit of 25km/h and other regulations, consumers will not be too harsh on the pursuit of electric vehicles, and consumers will spend several times more money to pay, I believe there is not much. People willing. Generally, the price of lithium batteries is several times that of lead-acid batteries, which reflects its low cost performance and does not meet the standard for general users to choose electric vehicles. Although the lithium battery has the characteristics of light weight, longer battery life and longer service life, the effect is not so clear in the actual operation process. Eighth, when replacing a lead-acid battery electric vehicle with a lithium battery, you have to consider the size of the battery compartment. Generally, the lead-acid battery compartment is relatively large, while the volume of the lithium battery is relatively small. This factor is well considered. If the gap is too large after installation, it is easy to cause the small battery inside to shake and reduce the life. Ninth, compared with lead-acid batteries, lithium batteries have poorer stability. If they encounter water or improper operation, they are prone to explosion risk. Therefore, this is the main reason why I do not recommend replacing lead-acid batteries with lithium batteries. Another thing to note is that the lithium battery is a multi-piece structure, as long as one of the problems occurs, it will affect the overall quality. In short, the lithium battery is not conducive to its promotion, whether it is a safety issue or a cost. Based on current technology, lead-acid batteries are still the mainstay. And want to change lead-acid electric vehicles to lithium batteries? The author of Energy Storage Electric suggests that you never try, except for safety. When the new national standard is implemented, the modification is likely to be a vehicle that exceeds the standard. If you really feel about the lithium battery Interested, it is recommended to buy a regular lithium battery.
