Are 3.7v 3000mah 18650 battery for electric cars safe?

　　As an indispensable tool for people's daily transportation, electric vehicles' safety has attracted more and more people's attention. As an important component of the power supply of electric vehicles, the safety of motors and 3.7v 3000mah 18650 battery is indeed the most fundamental guarantee for electric vehicles. Effectively design the safety distance of the battery support frame to provide a cooling method for the battery, which is conducive to the safe cooling of 3.7v 3000mah 18650 battery.

　　In fact, the lithium battery itself is not that risky, just because it needs a lithium battery protection system when it is used, and then it needs to be protected from accidents such as high temperature and strong impact when used. hazards of the situation. Relatively speaking, the maintenance of 3.7v 3000mah 18650 battery of electric vehicles is very strict. 3.7v 3000mah 18650 battery in electric vehicles undoubtedly present some safety risks. The safety and reliability of 3.7v 3000mah 18650 battery refer to the probability that the lithium battery will not become uncontrollable under normal operating conditions. Battery safety risks are extreme battery failures.

　　The 3.7v 3000mah 18650 battery of new energy electric vehicles that we know are suitable for fast charging, have a wide operating temperature range, and have a long service life. Therefore, the battery itself rarely explodes or catches fire, and is relatively safe.

　　Compared with the complex structure of traditional gasoline vehicles, the cause of electric vehicle fires is relatively simple, which is caused by the uncontrollable heat of the lithium battery. Smoke, fire and even explosion caused by uncontrolled heat are the most common characteristics of lithium battery failure process. Thermal failure is mainly caused by overcharge, external force, internal short circuit failure and other factors.

　　Among them, fire accidents caused by uncontrollable heat of power 3.7v 3000mah 18650 battery caused by external forces are more common. Because the power 3.7v 3000mah 18650 battery used in electric vehicles are composed of many 3.7v 3000mah 18650 battery, taking Tesla as an example, the complete set of power 3.7v 3000mah 18650 battery is very large and placed on the car chassis. In this way, it will be easier to extrude the lithium battery pack when the car collides, causing battery deformation, cracking, short circuit failure and other damage, resulting in uncontrollable heat.

　　The most terrifying thing is that the uncontrollable heat of one battery is likely to cause a chain reaction, causing the heat of the 3.7v 3000mah 18650 battery of other battery vehicles to be uncontrollable.

　　The driving force of lithium battery electric vehicles is similar to that of lead-acid batteries. After 6-8 hours of charging, the battery can travel 30-45 kilometers depending on the battery power, and the weight is only about 1/5 of the lead-acid battery. The biggest advantage of lithium battery electric vehicles is their long life. Note: It is said that the price of 3.7v 3000mah 18650 battery is only superficial. In fact, the carefully calculated cost is similar to that of lead-acid batteries. Nowadays, 3.7v 3000mah 18650 battery generally have a two-year warranty, and lead-acid batteries have a one-year warranty.

　　When using 3.7v 3000mah 18650 battery, it should be noted that the rechargeable battery will enter sleep mode after being left for a period of time. When the volume is less than the specified value, the use time will be relatively reduced. Lithium-ion batteries are relatively simple to activate. A normal battery can be activated and restored to its original capacity after 35 charging cycles. 3.7v 3000mah 18650 battery basically have no memory due to their own characteristics. Therefore, users do not need special methods and equipment when activating new 3.7v 3000mah 18650 battery.

　　Compared with lead-acid batteries, the ability of 3.7v 3000mah 18650 battery to withstand charging and charge-discharge fluctuations is much different. This is one of the clinical symptoms of the inability to properly select 3.7v 3000mah 18650 battery for high-power cars, which results in a reduction in durability. All in all, people are not saints, gold is not barefoot, and everything is not necessarily safe, but everything is relative. But I think: manufacturers of 3.7v 3000mah 18650 battery for electric vehicles must focus on physical safety and then consider the fundamental needs of consumers. The safety of 3.7v 3000mah 18650 battery will be addressed in the future.
