What is the quality of lithium batteries for electric vehicles?

The lithium battery has a long service life, light weight and small size. The energy performance of an electric bicycle with a lithium battery is similar to that of a lead acid battery (single electric bicycle). It takes 6-8 hours to charge and can work 30 hours. Up to 45 kilometers depending on battery capacity. It only weighs lead. About 1/5 of acid batteries, the biggest advantage of lithium battery electric bicycles is their long service life. Warning: People who say lithium batteries are expensive are only looking at their appearance. In fact, if you carefully calculate their cost, they are almost the same as lead acid batteries. Nowadays, regular lithium batteries have a 2-year warranty. lead acid batteries have a one year warranty.

Lithium batteries have non-activation characteristics. When using lithium batteries, it should be notedr that the battery will enter a dormant state after being left for a period of time. At that time, the capacity is less than. the normal value and usage time are also shortened. But lithium batteries are very easy to activate. It only takes 3-5 normal charge and discharge cycles to activate the battery and restore its normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, users do not need any special methods or equipment during the activation process of new lithium batteries.

No memory effect. When consumers charge lead-acid batteries and nickel batteries, they have always worried about the battery memory effect. After using lithium batteries, everyone can relax. effects. If there are still customers who don't know how to charge the batteries atlithium, you might as well read the following content.

Disadvantages of lithium battery electric vehicles

1. The price of lithium battery electric vehicles is too high because of the lithium battery. Nowadays, the price of lithium battery electric bicycles is generally several. times higher than that of electric vehicles with lead-acid batteries. One hundred to one thousand yuan, so it is difficult to obtain customer recognition in the market. Lithium batteries are lightweight, environmentally friendly, and will not cause environmental pollution after disposal. Once the application technology matures and market sales increase, the price of lithium battery electric bicycles will fall.

2. Charging lithium batteries for too long is counterproductive. Lithium batteries or chargers will automatically shut off once the battery is full. Therehas no so-called “maintenance” charge which continues for more than 10 hours. nickel battery chargers. That is, if your lithium battery is fully charged and placed on the charger, it will be charged in vain. And none of us can guarantee that the characteristics of the battery charge and discharge protection circuit will never change and the quality is fully guaranteed, so your battery will be on the verge of risk for a long time. This is another reason why we oppose long recharges. Additionally, on some electric vehicles, if the charger is not removed after charging for more than a certain amount of time, the system will not only stop charging, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own agenda, but it obviously hurts battery life. Therefore, after purchasing a lithium battery electric vehicleum, you should consult the company or dealer to do a good job of maintaining the lithium battery.

3. The energy performance of lithium batteries must be improved. Compared to lead-acid batteries, lithium batteries are much less resistant to charge and discharge fluctuations. effectively use lithium batteries for today's high-power vehicles. This is where durability decreases.

4. Lithium-ion battery safety issues remain unresolved. The safety of lithium batteries still needs to be improved. The danger of lithium batteries catching fire, extinguishing and exploding is nowIt still cannot be completely eliminated. A collision with the vehicle can cause the positive and negative materials of the battery to cross the barrier, and the instantaneous ultra-high current when the energy is quickly recharged to the battery during brakingge and other reasons may cause the battery to short circuit, increase the temperature, and cause a crash or even explosion. The cause of the fire is the precipitation of lithium ions caused by collision and short circuit. Contact with air will cause fire and extinction. Additionally, the electrolyte in lithium-ion batteries is an organic electrolyte, and these substances are more likely to ignite after contact with air.
