With the rapid development of household electric vehicles, the use of lithium batteries is becoming more and more popular, but the explosion and other dangerous accidents caused by lithium batteries are also increasing. Many people think that since lithium batteries are so dangerous, why don't they use other batteries, such as batteries? Today, in view of this problem and the safe use of lithium batteries, we will make a knowledge popularization.

After several years of development, lithium batteries are becoming more and more mature. At present, more and more electric vehicles use lithium batteries. Lithium batteries are widely recognized by the market for their small size, light weight, long service life, low temperature resistance and other advantages, especially for friends with higher and higher requirements for battery life, such as take away express brother, and office workers who are far away from home, Compared with the same battery, the battery life of electric vehicles with lithium battery is much longer. If you choose batteries because of the risk of lithium batteries, it's a bit of choking.

There are risks of lithium battery, but compared with the development of the whole industry, the risk of lithium battery needs more prevention and control and good management, rather than one size fits all elimination. So to help you understand the risk of lithium battery can help you better avoid the risk of lithium battery use.

How does the risk of lithium battery come into being? Let's see how to choose and use lithium batteries correctly

Select high-quality cell, spot welding with spot welding machine, and the wiring is neat

1. In order to pursue profit blindly, the bad business assembled batteries with inferior cells and sold them to users

2. Small workshop production, no formal production license and product testing report, poor process

There are many sellers (especially a treasure) in the market now. In order to pursue the lowest price, they use defective batteries as genuine ones to sell. The result is that the batteries will break down again and again soon, and then they can't find the place for maintenance (because express doesn't accept batteries). Besides the high failure rate and difficult maintenance, there are risks in the use of defective batteries.

So buy lithium batteries must find regular manufacturers. Manufacturers generally have cell test reports, as well as insurance, risk resistance ability is relatively strong, not as you have a problem, can not find people. Regular manufacturers have strict production process, quality assurance, after-sales is also true and effective. So don't buy "fake" batteries just because you're cheap.

3. Improper use by users (water, short circuit, collision, fire and heat)

In addition to the quality problems of the battery itself, many of them are caused by the improper use of users.

Water is the most taboo for lithium batteries. If the lithium batteries used by many people don't have a waterproof shell, it's easy to get into water when it rains. Especially if it doesn't dry in time after getting into water, it's easy to get into water, corrode nickel and cause short circuit. In this way, it's very dangerous for you to recharge.

In addition, the weather is too hot and it's dangerous to be exposed to the sun for a long time. It's better to "cool down" and recharge, because charging will also produce heat.

Try to choose an outdoor charging pile for lithium battery charging. Don't take it to your home for charging. You'd better watch it when charging at home. Don't plug in the charger for a long time when charging. Unplug the plug in time after charging.
