Which types of lithium batteries are contraindicated?

With the introduction of the new national standard, the era of lithium batteries has arrived. There are three main types of lithium batteries for electric vehicles on the market, the first ternary lithium (currently the most used), the second lithium iron phosphate, and the third lithium titanate. So, which ones should be paid attention to when using lithium batteries? At the first temperature, lithium batteries are afraid of high temperatures. Long-term overheating will greatly reduce the life of the lithium battery. In severe cases, the internal pressure will increase and cause an explosion. Even if there is no explosion, the lithium battery will quickly be scrapped in high heat. Most of the reason is because of the high temperature of the working environment. Caused by. The second largest current, such as the 18650 battery is 3C discharge, your electric car is 8000W, and the battery used is lower than the discharge current of your electric car, which will cause the lithium battery to have too high temperature, too much current and shorter life. There will also be bulging scraps. If your electric car is very powerful and fast, it is recommended to choose 18650 batteries with 10C current. It is obviously very important to choose the right battery! The third full charge storage, the full charge of the ternary lithium battery is 4.35V, the current protection board on the market is 4.2V and the charging is cut off, so many people buy the lithium battery for electric vehicles and say that there is no nominal capacity, but this is actually the case. The reason is that it is generally best to store the lithium battery of an electric car for a long time, and it is best to charge 50% of the TV. For example, if you buy a new mobile phone, most of it is powered by 50%. If the battery is fully charged and stored for a long time, the capacity of the lithium battery will be reduced. Except for lithium iron phosphate and lithium titanate, these two types can be stored at full power. It is also important to pay attention to choosing a better quality protection board. The biggest taboo of lithium batteries is overshoot and overdischarge, and ternary lithium can be overdischarged at one time. Scrap, overshoot must be scrapped. The fourth suitable charging equipment, when charging and discharging, the current of the charger and the general current load of the electrical appliance must be within the specified range. Excessive current load can easily cause the internal short circuit of the battery, thereby destroying the lithium ion and causing The safety hazard of the circuit. The same applies to the voltage of the rechargeable charger. So when we use the charger, we should also pay attention to see if the charger is qualified.
