With the rapid development of household electric vehicles, the use of lithium batteries is becoming more and more popular, but there are also more and more dangerous accidents such as explosions caused by lithium batteries. Many people think that since lithium batteries are so dangerous, why not use other ones, such as storage batteries? Today, I will give you a knowledge base on this issue and the safe use of lithium batteries.

After several years of development, lithium batteries are becoming increasingly mature. Currently, more and more electric vehicles on the market use lithium batteries. Lithium batteries have been widely recognized by the market for their small size, light weight, long life, low temperature resistance and other advantages, especially For friends who have increasingly higher battery life requirements, such as takeaway delivery boys, and office workers who live far away from home, electric vehicles using lithium batteries have a much longer battery life than equivalent batteries. If you choose storage batteries because of the risks of lithium batteries, it's a bit of a waste of time.

There are risks in lithium batteries, but compared with the development of the entire industry, the risks of lithium batteries require more prevention and control and good management, rather than a blanket elimination. Therefore, helping everyone understand the risks of lithium batteries can help everyone better avoid the risks of using lithium batteries.

How do the risks of lithium batteries arise? Let’s take a look at how to correctly select and use lithium batteries

Inferior products made by unscrupulous merchants (mixed use of various battery cells)

Use high-quality batteries, spot welding with spot welding machine, and neat wiring

1、In order to blindly pursue profits, unscrupulous businesses use defective cells to assemble batteries and sell them to users.

2、Produced in a small workshop, without formal production license and product testing report, poor workmanship

In today's market, there are many sellers (especially Baobao) who, in pursuit of the lowest price, use defective batteries as genuine batteries to sell. The consequence is that the batteries will fail repeatedly after a short period of time, and then the problem cannot be found. In the repair area (because express delivery does not accept batteries), the use of defective batteries not only has a high failure rate and is difficult to repair, but also has risks.

Therefore, when buying lithium batteries, you must find a regular manufacturer. Manufacturers generally have battery cell test reports and insurance, and are relatively strong in risk resistance, so you won't be unable to find someone if you have a problem. Regular manufacturers have strict production processes, quality assurance, and after-sales service is genuine and effective. So don’t buy ‘fake’ batteries just for cheap.

3、Improper use by the user (water, short circuit, collision, fire or heat)

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

Lithium batteries are most afraid of water intrusion. If the lithium batteries used by many people do not have waterproof shells, they will easily get water in when used on rainy days. Especially if they are not dried in time after water intrusion, water will easily corrode the nickel sheets and cause short circuits. It will be very dangerous if you recharge it and use it.

In addition, the weather is too hot and it is dangerous to be exposed to the sun for a long time. It is best to 'cool down' before charging, because charging will also generate heat.

When charging lithium batteries, try to choose outdoor charging piles. Do not take them home to charge. It is best to watch them while charging at home. Do not leave the charger plugged in for a long time when charging. Be sure to unplug the plug in time after it is fully charged.
