Can lead-acid batteries be changed to lithium batteries?

Now, let's take a look at how to change lead-acid electric vehicles to lithium batteries. Take a 48V lead-acid battery as an example: the first step is to open the four-corner screws of the battery and carefully open the upper cover. You can see that there are 4 12V lead-acid batteries inside. In the second step, after remembering the battery wiring, use an electric soldering iron to remove the wire from the battery. Take care to prevent the battery from short-circuiting during operation. The third step is to take out all the old batteries and put the lithium battery in. When the battery is installed, some small plastic protruding inside separates the original lead-acid battery. This must be removed, or the new battery will be worn out in the future. The fourth step is to connect the terminals on the battery, and then wrap them with electrical tape. However, it should be noted that when the original lead-acid battery is replaced with the lithium battery, it must be in accordance with the original car battery voltage, the capacity can be increased, and the battery life will be longer. Even with the same capacity, the range and life of lithium batteries will be longer. Secondly, it should be noted that the original charger cannot be charged with lithium, and it needs to be purchased separately or customized for a special charger. Of course, some people will ask whether the controller and motor need to be replaced? For lithium batteries, as long as the voltage is the same, a larger capacity is a good thing. The capacity of electric vehicles can be increased at will, as long as the voltage remains unchanged, the motor and controller have little effect. Of course, there is also a problem. If the quality of the lithium battery itself is defective, it is likely to burn out the controller. Since there are so many advantages of lithium batteries, why is it not recommended to replace lead-acid batteries 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. The most important reason is that there is a potential safety hazard in fire and explosion of lithium batteries, and no one is willing to buy a 'time bomb' under him. Especially when consumers are buying some low-quality lithium batteries online without their knowledge, the sealing conditions of electric vehicles are not very good, and it is easy to cause safety hazards due to poor contact due to humidity and other reasons. Some people may say that now, 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. In my opinion, although lithium batteries have the same weight and volume compared to lead-acid batteries, the storage capacity of lithium batteries is generally about three times higher than that of lead-acid batteries. However, for an electric vehicle as a means of transportation, the effect 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. Coupled with 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 it is believed that not many people are willing to spend several times more on the bill. 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. Want to change lead-acid batteries to lithium batteries? I suggest never try, it still matters! Disclaimer: Some pictures and content of articles published on this site are from the Internet.
