Key factors affecting the service life of power batteries

For power lithium batteries, the key factor that affects the frequency of recharging the rechargeable battery, which is the cycle life, mainly comes from two aspects, not only the rechargeable battery itself, but also not only from the outside world. The answer is no doubt. In fact, for power lithium batteries, the key factor that affects the charging frequency of the cycle battery is the key factor of the cycle life. It mainly comes from two aspects, not only the rechargeable battery itself, but also not only from the outside world. Everyone depends on which key external factors affect the frequency of battery charging cycles. First of all, the usual use, such as the ambient temperature of the rechargeable battery in use and the degree of discharge of the rechargeable battery, etc., all affect the cycle life of the rechargeable battery. In addition, the timing of battery charging is also very important. Generally speaking, it is recommended to use shallow charge and shallow discharge for rechargeable batteries. If overdischarge or overcharge occurs, it will actually have a greater impact on battery life. Generally speaking, keep the power from 25% Between ~75%, you must not wait until the battery is completely discharged before recharging the battery. In the end, the use of different battery charging methods will also affect the cycle life of the rechargeable battery. For example, there are two main types of car charging piles on the market at this stage, one is fast charging piles and the other is slow speed car charging piles if they are used frequently. The fast charging pile charging will also affect the cycle life of the rechargeable battery. After looking at the external factors, let's talk about the factors affecting the rechargeable battery itself. First, the most important factor that determines the number of rechargeable battery cycles is the electromagnetic material. For example, the two types of rechargeable batteries that are mainstream in new energy electric vehicles at this stage, ternary lithium batteries and lithium iron phosphate batteries. The two types of rechargeable batteries use different cathode materials. In the later use, the characteristics of the two types of rechargeable batteries are different. At the same battery charging rate, the cycle battery charging frequency of the lithium iron phosphate rechargeable battery can reach 2000 times. , And the battery charging cycle frequency of the ternary lithium battery can only reach 1000 times, which has shown that the material has a very large impact on the service life of the rechargeable battery. Is the cycle frequency related to the rechargeable battery itself? The second is the quality of lithium batteries. At this stage, many rechargeable battery manufacturers are providing lithium batteries for new energy electric vehicles, but each brand has its own characteristics, and the quality is also uneven. Although theoretically speaking, as long as the charging cycle frequency of the lithium battery of the same specification is the same, the different processing technology used by different brands will also cause the later life to be different. In the end, in addition to the power lithium battery pack of the lithium battery itself, a complete set of intelligent management system for rechargeable batteries is needed. This intelligent management system can make the lithium batteries charge and discharge more effectively, which has a great impact on the cycle life of the rechargeable batteries. For example, the thermal intelligent management system and the balancing system of rechargeable batteries are all essential for power lithium battery packs. The rechargeable battery's cycle battery charging frequency represents the cycle life of the rechargeable battery, and the key factors that affect the cycle life of the rechargeable battery are all related to the rechargeable battery itself and the key factors in use. For new energy electric vehicle owners, we cannot determine the influencing factors of the rechargeable battery itself, but we can extend the cycle life of the power lithium battery based on cultivating better car usage habits. This is what we can do. Disclaimer: The articles published on this site are from the Internet and do not represent the views of this site.
