CR2354 battery.Pay attention to these points for lithium-ion batteries in electric vehicles

　　Nowadays, electric vehicles are increasingly developing towards high-end intelligence. The research and manufacturing technology of electric vehicles is constantly improving, and the production process of electric vehicles is also becoming increasingly mature. But there is one drawback that has always hindered the development of electric vehicles, which is batteries!

　　With the introduction of new national standards, the era of lithium batteries has arrived. The lithium batteries for electric vehicles in the market are mainly divided into three categories: the first ternary lithium (currently the most commonly used), the second lithium iron phosphate, and the third lithium titanate. So, what do you need to pay attention to when using lithium batteries?

　　The first temperature, lithium batteries are afraid of high temperatures. Long term exposure to overheated environments can significantly reduce the lifespan of lithium batteries. In severe cases, explosions may occur due to increased internal pressure. Even if there is no explosion, lithium batteries will quickly be scrapped in high heat, mostly due to the high temperature of their working environment.

　　The second largest current, for example, the 18650 battery cell is 3C discharge, and your electric vehicle is 8000W. The battery cell used is lower than the discharge current of your electric vehicle, which can cause the temperature of the lithium battery to be too high, the current to be too large, and the lifespan to be short. There may also be cases of bulging and scrapping. If your electric vehicle has a very high power and speed, it is recommended to choose a 18650 battery cell with a current of 10C, which is obviously very important to choose a suitable battery cell!

　　The third fully charged storage is the ternary lithium battery, which has a full charge of 4.35V. Currently, the protection board on the market is 4.2V and stops charging. Therefore, many people buy electric vehicle lithium batteries and claim that they do not have the nominal capacity. In fact, this is the reason. Generally, storing electric vehicle lithium batteries for a long time and fully charging 50% of the TV is the best. For example, when you buy a new phone, many of them have a 50% power when turned on. If fully charged and stored for a long time, it will reduce the capacity of the lithium battery. Except for lithium iron phosphate and lithium titanate, which can be stored at full charge, it is also important to choose high-quality protective plates. The biggest taboo for lithium batteries is overcharge and overcharge. Ternary lithium is scrapped once overcharged, and overcharge is bound to cause bulging and also scrapping.

　　The fourth suitable charging device should also ensure that the current of the charger and the general current load of the appliance are within the specified range during charging and discharging. Excessive current load can easily cause internal short circuits in the battery, thereby damaging lithium ions and posing safety hazards to the circuit. Similarly, the same applies to the voltage of a charging charger. So when using a charger, we also need to pay attention to whether the charger is qualified.
