For power batteries, the factors affecting the number of charging cycles and service life are mainly from two aspects: the battery itself and external factors.

First, let's look at the influence of external factors on the number of charging cycles.Battery recycling The first is the situation in daily use, such as the temperature of the battery and the degree of discharge during use will have an impact on the service life of the battery. In addition, the timing of charging is also important. Generally speaking, it is recommended to use the battery with shallow charging and discharging to avoid over-discharging or over-charging. It is best to keep the charge between 25% and 75% and not wait until it is completely discharged. Finally, different charging methods will also have an impact on the service life of the battery. There are two main types of fast charging piles and slow charging piles on the market today, and if you often use fast charging piles for charging, it will also have a certain impact on the service life of the battery.

Next, let's look at the influencing factors of the battery itself. First of all, electromagnetic material is one of the main factors that determine the number of battery cycle charging. For example, the ternary lithium batteries and lithium iron phosphate batteries,cylindrical cell assembly machine which are currently used in the mainstream of electric vehicles, use different cathode materials. The characteristics of these two types of batteries in later use are different, and at the same charging rate, the number of cycle charge times of lithium iron phosphate battery can reach 2000 times, while the number of cycle charge times of lithium ternary battery can only reach 1000 times. This is enough to show that the impact of the material on the battery life is very big.

Secondly, the quality of the battery cell is also an important influence.battery making machine Currently there are many battery manufacturers to provide electric cells for electric vehicles, but each brand has its own characteristics, and the quality varies. Although theoretically, the number of charging cycles should be the same for batteries of the same specification, the different production processes used by different brands result in different lifespans at a later stage.

Finally, in addition to the battery cell itself, the power battery pack also requires a comprehensive battery management system. This system allows the electric cell to be charged and discharged more rationally, which has an important impact on the service life of the battery. For example, the thermal management system and the battery equalization system are both critical for power battery packs.

To summarize, the number of cycle charges of a battery represents its service life, and the factors affecting the service life of a battery are closely related to the battery itself and usage factors. For pure electric vehicle owners, the influencing factors of the battery itself cannot be decided, but we can extend the service life of the power battery by developing good vehicle habits, which is something we can do.
