What should I pay attention to when replacing lead-acid batteries in electric vehicles with lithium batteries?

1. The production cost of lithium-ion batteries is high, and the production equipment is expensive. The labor cost accounts 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-ion battery is difficult to recycle, and the reuse rate is not high. 2. Due to the small size of lithium-ion batteries, there are multiple lithium-ion 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 lithium-ion batteries are connected. 3. The high-current discharge characteristic of lithium battery itself is a shortcoming. Think about the frequent start-up of congested roads, the battery life will be greatly reduced. The important reason is that lithium-ion batteries have a potential safety hazard in fire and explosion, and no one is willing to buy a bomb on time. Especially when consumers buy some low-quality lithium-ion 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-ion battery technology, this kind of problem will not occur, but no one can guarantee that this kind of problem will not occur. It should be noted that when the original lead-acid battery is replaced with a lithium-ion battery, the voltage must be consistent with the original car battery, the capacity can be increased, and the battery life will be longer. Even with the same capacity, the range and life of lithium-ion batteries will be longer. Secondly, it should be noted that the original charger cannot be charged with lithium batteries, and a special charger must be purchased separately or customized.
