Lithium battery electric vehicles have what advantages and disadvantages

Lithium battery electric concise gorgeous appearance, more and more accepted by consumers, that lithium battery electric car in the end it really good? Lithium battery electric vehicles What are the advantages and disadvantages? The lithium battery has a long life, light weight and small volume, and has an activation-free property with a memory effect. The disadvantage of lithium battery electric vehicles is that the current price of lithium battery electric bicycles is generally several hundred to one thousand higher than that of lead-acid battery electric vehicles, so it is difficult to get recognition from consumers in the market.

Lithium battery electric car how to introduce the advantages and disadvantages of lithium battery electric car

Lithium battery electric car gorgeous and concise shape, more and more accepted by consumers, how good is the lithium battery electric car? Is it really so good to everyone?

Nowadays, the most popular ones are lead-acid battery electric vehicles, but many regions have begun to introduce lithium-ion battery electric vehicles. Lithium battery electric vehicles, as the name suggests, simply replace the lead acid with a lithium battery. Compared with lead-acid batteries, is the electric vehicle lithium battery good? Does it really have a business, is the dealer so eloquent? Nowadays, the country strongly advocates energy conservation, greenness, and environmental protection, and it is really popular. The questions have not been answered.

When it comes to electric vehicle lithium batteries, is it good? Everyone's point of view is very consistent. "Lithium batteries are lighter than lead-acid batteries and have a long life, but the price is very expensive." Everyone seems to be unable to answer the words.

Lithium battery electric car advantages:

Lithium battery has long life, light weight and small size

The power performance of the lithium battery electric bicycle is similar to that of the lead-acid battery (simple electric bicycle). It can be charged for 6~8 hours. It can run 30~45 kilometers depending on the battery capacity. The weight is only about 1/5 of the lead-acid battery. The lithium battery is electric. The biggest advantage of bicycles is their long life.

Disclaimer: The price of lithium batteries is only expensive to see the surface. In fact, the cost of the calculation is quite similar to that of lead-acid batteries. At present, lithium batteries are generally guaranteed for 2 years, and lead-acid batteries are guaranteed for 1 year.

Lithium battery has no activation characteristics

In the use of lithium batteries, it should be noted that after the battery is placed for a period of time, it enters a sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, the lithium battery is easy to activate, as long as the battery is activated after 3 to 5 normal charge and discharge cycles, and the normal capacity is restored. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the user's new lithium battery does not require special methods and equipment during the activation process.

Lithium battery with memory effect

When consumers charge lead-acid batteries and nickel batteries, they are always worried about the memory effect of the battery. When a lithium battery is used, everyone can breathe a sigh of relief. The lithium battery has no memory effect. If there are consumers who don't know how to charge the lithium battery, and then look at the following.

Disadvantages of lithium battery electric vehicles:

Lithium battery electric car price is too high due to lithium battery

At present, the price of lithium battery electric bicycles is generally several hundred to one thousand higher than that of lead-acid battery electric vehicles, so it is difficult to get recognition from consumers in the market. Lithium batteries are light and environmentally friendly, and will not cause environmental pollution after being discarded. Once the application technology is mature and the market sales increase, the price of lithium battery electric bicycles will drop.

Lithium battery charging time is too long to be counterproductive

The lithium battery or charger will automatically stop charging when the battery is fully charged. There is no so-called “turbulent” charging that the nickel battery charger has for 10 hours. In other words, if your lithium battery is full, it will be white charger on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the edge of danger for a long time. This is another reason why we oppose long charging.

In addition, in some electric vehicles, after charging for more than a certain period of time, if the charger is not removed, the system will not stop charging, and the discharge-charging cycle will start. Perhaps the manufacturer of this approach has its own purpose, but it is obviously unfavorable for the life of the battery. Therefore, after purchasing a lithium battery electric vehicle, you should consult a company or dealer to do a good job in lithium battery maintenance.

Lithium battery power needs to be improved

Lithium batteries have much less resistance to fluctuations in charge and discharge than lead-acid batteries. For the current high-power vehicles, a large symptom of lithium batteries cannot be effectively used, resulting in a decrease in durability.

Lithium-ion battery safety issues stand out

The safety of lithium batteries still needs to be improved. The hidden dangers of lithium batteries burning, burning and even exploding are still not completely eliminated. Collision of the vehicle may cause the positive and negative materials of the battery to break through the diaphragm, and the ultra-high current instantaneously when the energy is quickly recharged to the battery during braking will cause the battery to short-circuit, increase in temperature, cause combustion or even explosion. The cause of the fire is that lithium ions are precipitated due to collision or short circuit, and fire and combustion may occur when contact with air. In addition, the electrolyte of a lithium ion battery is an organic electrolyte which is more likely to ignite upon contact with air.
