Is it better to replace lithium batteries in electric vehicles or lead-acid batteries?

Lead-acid batteries are more cost-effective. Let’s take Tianneng’s 60/20 battery as an example. Lead-acid batteries are traded at 350 (a car dealer’s price was even higher some time ago), lead-acid batteries for lithium batteries are at least 1,200, and lead-acid batteries are three packs of 15 months. According to the battery I replaced in the store, the general life span is about 2 years, three packs of lithium batteries are 27 months, and the maximum life span is 5 years. Under the same price, lead-acid can be exchanged for 3.5 sets, and lead-acid can be used for the same price. With 7 years of use, lithium batteries can only be used for 5 years, and the cost performance is self-evident. In terms of maintenance costs, lead-acid batteries once again completely win out. As long as the lead-acid battery is installed in the early stage, there will be basically no safety problems. The most important thing is that there is no need to maintain it in the later stage; but the lithium battery is not the same. It is afraid of heat, cold, collision, and water. . The advantages of lithium batteries are not necessarily advantages. For example, light weight is good, but if the model design is not changed, too light weight will cause the vehicle to drive instability and cause many safety hazards. We once took the same type of lead-acid and lithium batteries and their driving mileage was not much different. Solve the used batteries. Every time you sell used batteries, lead-acid products are scrambling to collect; but you don’t need any lithium voltage roots. If you want it, you have to say a lot of good things for 10 yuan. Therefore, there is still no advantage in the lithium battery of used batteries. What battery to change when the tram is dead? Still replaced with a lithium battery. Lithium battery has long life and light weight. If you consider safety, it is better to change to iron lithium! Although the cost is higher, the performance is better. However, it should be noted that the weight of the tram has been reduced a lot after the change, and the brakes have been adjusted, and there is also a process of adaptation. In addition, lithium battery chargers must be used for lithium batteries, and the original lead-acid chargers can no longer be used. Lithium batteries must have a protection circuit. When the protection value is lower, the electric car will not be powered. Unlike a lead-acid battery, it can run slowly for a period of time when the battery is low.
