How many times have lithium-ion battery manufacturers analyzed the charging and discharging of lithium-ion batteries?

How many times does lithium-ion battery manufacturer Haobo inform you of the charging and discharging times of lithium-ion batteries? The lifespan of lithium-ion batteries is generally determined by the number of charging cycles, which refers to the process in which the battery's charge drops from zero when the battery is full and then charged. Whether it is a ternary lithium-ion battery or a lithium iron phosphate lithium-ion battery, if the shallow discharge and shallow charging method is used, its service life will be greatly extended, and the charging cycle of the ternary lithium-ion battery can easily exceed 1000 times.

How many times have lithium-ion battery manufacturer Cameroon notified you about the charging and discharging issues of lithium-ion batteries?

When it comes to the cycle of lithium-ion batteries, it is common to encounter charging cycle issues. In fact, both have the same meaning. You can say that the cycle of a battery is calculated based on a cycle, or vice versa. That's too much to say.

What is the charging cycle? The charging cycle refers to a complete charging and discharging process of a lithium-ion battery. That is to say, when the battery reaches 100% charge, it ends a charging cycle, but it may not necessarily end with a single charge. This is a misunderstanding among many people.

The lifespan of lithium-ion batteries is 500 charges. How can it be considered a charge discharge cycle? A charging cycle means that a lithium-ion battery is fully charged from full to full, from empty to full, which is different from a single charge. The so-called 500 cycles refer to lithium-ion battery manufacturers completing about 625 rechargeable cycles within a stable discharge depth (80%), reaching 500 charging cycles. The formula is clearer: 625 x 80%=500. (Ignoring factors such as reduced capacity of lithium-ion batteries)

In practice, 500 charging cycles can only be considered as observation, as they are affected by various factors throughout the day, especially unstable charging and timely discharge depth. Imported ternary lithium-ion batteries have a charging and discharging frequency of about 3000 times, while domestically produced lithium-ion batteries have a charging and discharging frequency of about 800-1000 times.

Ordinary lithium-ion batteries have a high charge and discharge frequency of up to 2000 times. Lithium ion batteries include ternary lithium-ion batteries, iron lithium-ion batteries, and polymer lithium-ion batteries, all with intervals. Ordinary lead-acid batteries can charge and discharge up to 500 times.

The current lithium-ion batteries for new energy vehicles are mainly used for ternary lithium-ion batteries, cobalt oxide lithium-ion batteries, and iron phosphate lithium-ion batteries. Regardless of the type of battery, it has status and authority to measure, charge, and discharge the battery life cycle in accordance with the law. The battery's service life will be even shorter. For power lithium batteries, the battery cycle must be at least 1000 times. Lithium iron phosphate can be used 2000 times, while ternary lithium-ion batteries can generally be used 1000 times or more.

Different batteries have different cycle lifetimes. The cycle life of ternary lithium-ion batteries is 1500-2000 times that of ordinary lithium-ion batteries. So relying solely on the number of charges will not affect the battery life. The lifespan of power lithium batteries is determined only by the number of cycles. The number of charging cycles does not directly determine the lifespan of power lithium-ion batteries. Multiple charges within a charging and discharging cycle can only be counted as one battery loss cycle. So when using electric vehicles, don't worry about the number of charges that may affect the lifespan of lithium-ion batteries.
