Why is the current lithium battery electric locomotive gradually replacing the battery electric locomotive?

1. Fast charge. Lithium batteries support fast charging and no gas emissions, while lead-acid batteries do not support fast charging and emit harmful gases. In terms of charging time, lithium batteries only need 2-3 hours to charge, while lead-acid batteries must be at least 8-9 hours. 2. Free of protection. Customers who have used lead-acid batteries know that it is necessary to regularly add electrolyte for protection to lead-acid batteries, which is troublesome and has high labor costs. When charging a battery, someone may have to stay by and watch the charging. However, do not add any lithium batteries. If the electrolyte is full, the power will be cut off immediately, saving labor costs. 3. Use life span and cost. From the first purchase cost, the price of lithium batteries will be about 2.5-3 times that of lead-acid batteries, but from a long-term point of view, lead-acid batteries may have to be replaced once a year if they are well protected. It is possible to change a set for half a year, and the life span of lithium batteries can reach 3-5 years. Therefore, the initial cost of lithium batteries is relatively high, and the later protection, replacement costs and labor costs are much lower than those of lead-acid batteries. The price comparison can be seen in the figure below: Lithium battery and lead-acid battery price breakdown 4. Rechargeable and ready for use. Lithium batteries are different from lead-acid batteries. Lead-acid batteries must be overcharged before they can be used, otherwise it will affect the life of the battery. Lithium batteries can be charged and used without affecting the life and are easy to use. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
