Which of the lead-acid batteries and lithium batteries is more cost-effective for electric vehicles?

We searched for a certain brand of lead-acid battery from a treasure. The price of 60V20Ah is 1068 yuan, and the price of trade-in is 718 yuan. Based on the service life of lead-acid electricity for one year and the use time is three years, then replace the lead-acid battery The total cost is 2504 yuan. Lead-acid batteries are relatively cheap, which means that the cost performance is relatively high, and their quality is relatively good. It is not cheap that the quality is poor. Generally speaking, it is more cost-effective to buy lead-acid batteries. Lithium batteries are usually very much in contact with us. Take a mobile phone as an example. After a mobile phone has been used for 1-2 years, the battery life is not as good as in the past, but few people will consider replacing the battery within two years. As we all know, our mobile phones warn when the battery is less than 20%. Most people will choose to charge the mobile phone at this time. From 20%-100% overflow, we only use 0.8 cycles of charging and discharging. According to this Frequency The number of cycles of charging and discharging lithium batteries in two years is 365*2*0.8u003d584 times. Take a certain brand battery of a certain treasure as an example. The price of a lithium battery 60V20Ah is 1898 yuan. According to our above data, the lithium battery has been used for two years in a total of 584 cycles of charging and discharging. Then this time the lithium battery is charged and discharged. The capacity is only 20% lost, and the remaining 80% of the battery capacity can still meet your daily riding. The service life of lead-acid batteries is generally about 2 years, while lithium batteries for electric vehicles are more durable, with a life span of 4-5 years; and lead-acid batteries are generally fully charged and discharged within 300 cycles, while lithium batteries are fully charged and discharged. More than 500 times. At present, mainstream lead-acid batteries on the market are about 450 yuan, while lithium batteries are more expensive at about 1,000 yuan; the prices of the two types of batteries are different, and the prices of the corresponding electric vehicles are also quite different. At the same time, the warranty period of lithium batteries is one year longer than that of lead-acid batteries, and can be guaranteed for two years. Compared with lead-acid batteries, which are difficult to operate, bulky, and not durable, lithium battery electric vehicles seem to have more advantages. The current brands of lithium battery electric vehicles are diversified, such as Yadi, Giant, Emma and other lithium electric vehicles. Charging for 6 to 8 hours, depending on the battery capacity, it can run 30 to 145 kilometers, and the weight is only about one-fifth of the lead-acid battery. The biggest advantage of lithium battery electric bicycles is long life. The only thing that says that lithium batteries are expensive is to look at the surface. In fact, the cost is about the same as lead-acid batteries. At present, lithium batteries are guaranteed for 2 years, while lead-acid batteries are guaranteed for 1 year. So the quality of cheap goods is naturally compromised. Lithium batteries are basically no problem for 3-5 years. In summary of some of the above issues, it is recommended that users choose lithium batteries as much as possible if they have sufficient funds. After all, in terms of electric vehicles, battery life is the biggest use. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
