Life analysis of different types of lithium batteries for electric vehicles

1. Electric vehicle batteries made of polymer lithium batteries. Few electric vehicle lithium batteries currently on the market use polymer lithium batteries, and some are basically more expensive customized or self-modified. In theory, the lifespan of the lithium battery for electric vehicles made of polymer lithium batteries is about 500 cycles. If it is discharged once every two days, then it is one thousand days, which is close to three years. It should be noted here that polymer lithium batteries must be specially used for power lithium batteries for electric vehicles, otherwise they will be scrapped after a short period of time. 2. 18650 cylindrical lithium batteries or square aluminum shell lithium batteries. The lithium batteries for electric vehicles currently on the market are basically 18650 lithium batteries or square aluminum shell lithium batteries. The properties of these two batteries are basically the same, and the service life is also 300 In general, the life of a power lithium battery with a relatively good quality is basically about 400 cycles when it reaches 400 cycles. Therefore, after using an electric vehicle for a year, it is obvious that the battery is not working well. This is the reason. Of course, after an electric vehicle is used for a period of time, the capacity degradation of the lithium battery and the increase of the internal resistance are important reasons, but other electronic components will also age, the electronics will increase, and the power consumption will increase, such as the coil of the motor or others. It will also affect the endurance of electric vehicles. 3. Electric vehicle batteries made of lithium iron phosphate batteries. With the development and progress of lithium iron phosphate battery technology, some of the lithium iron phosphate batteries for electric vehicles are now slowly using lithium iron phosphate batteries, because lithium iron phosphate batteries are used for electric vehicle lithium batteries. In theory, the service life can reach more than 2000 times. The power lithium iron phosphate battery has a service life of 1000 cycles and can achieve a certain rate of discharge (supporting high current discharge). In addition, it is also a lithium battery in terms of its safety performance. The best in the family. Disclaimer: The articles published on this website are all from the Internet.
