How to write a model essay on the company's vehicle battery replacement application?
Part 20: Our company wants to apply for changing the lead-acid battery of electric vehicles into lithium batteries, hoping to be approved. It is not recommended to replace lead-acid batteries with lithium batteries. First, the production cost of lithium 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 3 times that of lead-acid batteries. Its triple price brings low performance-to-price ratio, which gives people a flashy feeling. It is difficult to recycle lithium batteries and the reuse rate is not high. Secondly, due to the small size of lithium batteries, there are many lithium batteries connected in series during assembly, which may cause a solder joint to be broken or virtual welded during transportation and use, which is a common problem when connecting lithium batteries. Thirdly, the high current discharge characteristic of lithium battery itself is short board. Considering the frequent start of congested road sections, the battery life will be greatly reduced. The most important reason is that there are hidden dangers of fire and explosion in lithium batteries, and no one will be willing to buy the "time bomb" under it. Especially in the case that consumers don't know, some inferior lithium batteries are found on the Internet, and the sealing conditions of electric vehicles are not very good, which may easily lead to poor contact and potential safety hazards. Some people may say that lithium battery technology is developing rapidly now, and this problem will not occur, but no one can guarantee that this problem will not occur.
