Are lithium battery electric vehicles any good? It depends on the specific model and configuration. We cannot generalize. Regarding the detailed description of the problem by the interlocutor, the answer is as follows:
1. Regarding the comparison between the cruising range of lithium batteries and that of batteries lead previously used.
Under the same conditions, theoretically speaking, as long as the capacity and rated voltage of the lithium battery are equivalent to that of the lead-acid battery, the mileage will be the same on the same section of road and in the same driving conditions. Compared with the above, lithium battery electric vehicles are superior or equal to lead-acid battery electric vehicles. The reason is that the chassis of most lithium battery electric vehicles is about 20% lighter than that of electric vehicles.es lead-acid battery, and that the battery is 30% to 60% lighter (depending on the cell material). The load is reduced and the mileage is naturally longer.
Specific analysis is required in real use. The most commonly used materials in lithium batteries are cobalt-lithium, manganese-lithium, ternary lithium, and iron-lithium. The use of lithium-cobalt is gradually decreasing, let's leave that aside.
Performance at different ambient temperatures: When used in winter, the performance of lithium manganese and ternary lithium is zero; better than that of lead acid batteries. Iron and lithium are basically equivalent to lead-acid batteries at around minus 15 degrees Celsius. In the other three seasons, the performance of lithium batteries is better than that of lead-acid batteries.
Comparison of lifespane: Under full/discharge conditions, the life of lithium manganese is 500 times, that of ternary lithium is 1000 times, and that of lithium iron is 2000 times. Lead acid battery 350 times. If we look at the years of use by most people, the order is lithium manganese battery for 2 years, Sanyuan battery for more than 3 years, lithium iron battery for more than 5 years, and battery lead for a year and a half. . (No need to talk about those who run express delivery or deliver fast food. Your frequency of use and mileage cannot be compared to ordinary people, so don't enter into the discussion)
< p> As for the comparison in terms of money, except for iron-lithium Except for the performance-price ratio comparable to that of lead-acid batteries, other lithium batteries fail miserably.
Compared to the commosaid and light when charging, all lithium batteries beat lead acid batteries. Our compatriots understand this very well.
2. Regarding charging and security issues.
The problem mentioned in the question that lithium batteries need to be charged frequently is a false proposition. I would like to ask which electric car can keep driving for a long time without recharging after being charged once? If you want to charge it as soon as you use it, this will extend the life of the lithium battery and save you money. If it's inconvenient, just spend more money. For lead acid batteries, charging them as soon as they are used until the green light comes on and then stopping charging will also extend their life. If you don't understand or half understand, don't make excuses: let me ask you a question: when uno one works alone, should she work until she is almost exhausted then rest, or should she work for a while then rest. Which one has a long life?
As for the safety issues, they are all related to the charger, protective board, cell quality, materials, packaging process, environment of use and collisions. The safety of using iron-lithium and manganese-lithium and lead-acid batteriesIn fact, ternary lithium is almost the same.
3. Regarding performance and price. As mentioned earlier, lithium iron is the most cost effective and has a long lifespan. Performance dipped in winter, but when the weather warmed up, it returned to full health. I have never driven a new national standard lithium battery electric vehicle, so I can't talk nonsense. However, the two electric vehiclesTwo wheels I use both use lithium batteries. One of them is a 48V12AH lithium iron transformed lead-acid battery electric vehicle. I have been using Lianmaoer for 8 years and I can still run 25 kilometers. Do you think this is a good deal or not?
I recently bought a Luyuan brand national standard electric bicycle, 48V24A lithium battery, 3899 yuan. The price is relatively expensive, the battery alone costs around 1,600 yuan. The first charge after purchase took about 7 hours. Once fully charged, I drove over 40 kilometers intermittently in 22 days (using an odometer). It is always powered and can travel around 50 kilometers without any problems. Since the speed limit is 25 kilometers, electricity consumption is relatively low. If you use it daily, the mileage may be higher because it uses electricity without leaving it there.The battery weighs 9.8 kg and can be taken home for recharging. The advantage is that it accelerates faster while driving and has better hill climbing ability than my original car with lead acid batteries. This lithium battery is a special support battery for Luyuan Yadi Emma. It does not generate heat when charging (the charger is very hot) and is relatively safe.
Please read the “Instruction Manual” and do not modify the vehicle without authorization.
I was previously confused about this question and didn't know how to choose. Now that I have used both lithium battery vehicles and lead acid vehicles, I can tell you about their characteristics. The main advantage of lithium batteries is that they are lightweight and easy to charge. It is the best choice for users who live in apartment buildings. As for power and lifespane of the battery, there is no significant difference between the two batteries in hot weather. But during the cold winter season, when the temperature is below 10 degrees, the power of lithium batteries attenuates more significantly than that of lead-acid batteries. If fully charged, the lithium battery will lose about half its power and the lead-acid battery will lose about a third. Therefore, in winter, lead-acid batteries are more durable than lithium batteries. Other situations should be easy to understand. How to choose depends on the actual usage needs. Personally, I think it is better to choose lithium batteries.
Lithium batteries are certainly better than lead-acid batteries and are characterized by good safety performance.
Lithium batteries are good, but they are not safe. These are essentialLithium batteries catch fire when charging.
Dear, you don't actually need to change the car, just change the battery. I can tell you from personal experience that 7 years ago I made a set of 4830 lithium iron phosphate batteries using grade B cells produced by the company I worked for at the time, and they only ended this year. Note that this is product B, lithium iron phosphate. If it is Grade A lithium iron phosphate, it may be able to be used for a longer period. Considering the safety concerns, there is no difference in the choice of iron and lithium phosphate. Lithium manganate may also be considered. For example, lithium manganate from Phylion Power is very good. Three yuan, hum, there is a risk of catching fire, even if it's a one in ten thousand chance, it's a story ifIt happens to others, but it happens to you. It's an accident.

The most durable and cheapest electric car
Personally, I think lead acid batteries for electric cars are better than lithium batteries.Generally, lead-acid batteries are used in electric vehicles, mainly due to their high cost.
The difference between the two:
Lead acid batteries are hard and drop resistant, cheap and have the advantage of being recyclable and repairable, however, they are of big size ; but have small capacity and short lifespan.
Lithium batteries are small, light, have large capacity, have a long life, and have good resistance to charge and discharge. However, they are expensive and cannot be recycled, posing safety risks.
Advantages of lead acid batteries: ?
1. Difficult: The lead-acid battery leader has always been guided by the principle “Let it be strong when it is strong. , the breeze caresses the hills, he is allowed to do what he wants, and the moon shines." The magical principle of the Nine Yangs of Dajiang. It can bebeaten and beaten by you, and after a little repair, it can continue to be used. It's really easy to make a living. ?
2. Cheap: Lead-acid has always been the leader in electric vehicle batteries. This reason cannot be ignored at all. The price is only about a third of that of lithium batteries. ?
3. Recyclable Reverse Repair: This lead boss skill is a unique skill. Once worn out, you can go to an electric vehicle store to pay the difference and exchange the old one. for a new one, which can minimize the loss for the user, it can be said to be a great benefit. ?
Disadvantages:
1. Large volume and weight, but relatively short capacity. ?
2. The lifespan is short. Lead-acid batteries are generally deeply charged and discharged within 400 times.
Advantages of lithium batteries: ?
1. Lightweight andsmall size: Compared with lead-acid batteries of the same capacity on the market, lithium batteries, which have been used lightly. since childhood, are smaller. They represent 2/3 of the volume of a lead-acid battery and its weight is approximately 1/3 of the weight of a lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead acid batteries. Reducing weight increases the range of electric vehicles by around 10%. ?
2. Longer lifespan: Lithium batteries are well known for their health. The average lifespan of lithium batteries is about 4 years, about 1.5 times longer than lead-acid batteries. charged and discharged more than 500 times. No memory to use, strong shock resistance. ?
3.Good resistance to charge and discharge: lithium batteries have been opened since childhood, so under normal temperatures, lithium batteriesm can be continuously charged for 48 hours without expansion, leakage, rupture and other accidents, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly. ?
Disadvantages of lithium batteries:
1. High price: The production cost of lithium batteries is high, and labor costs account for about 40% of the cost. production cost, and the price is about lead-acid. The battery is about three times the size, but the value for money at three times the price isn't high and it looks pretty flashy. ?
2. Non-recyclable: Lithium batteries are not recyclable. Once worn out, they can only be thrown away or buried somewhere until after thousands of years, future generations will dig them up and become antiques. . ?
3. Safety Risks: The most important problem is that lithium batteries pose fire risks et explosion, especially when consumers are unknowingly deceived by profiteers and buy inferior lithium batteries. not very good, and it is easy for humidity to cause poor contact and other reasons, which may cause safety hazards. ?
In short, lead-acid batteries and lithium batteries each have their own advantages and disadvantages. If you want to install a high-quality and reliable battery for your car, let it be a lead-acid battery. if it is a battery or lithium battery, you still need to first check whether the battery manufacturer is trustworthy and whether it is produced by a regular manufacturer like Jingqiu.
