The key to pure electric vehicles is the power battery. For power batteries, power battery performance indicators, capacity, service life, etc., are used to measure one of the performance indicators of the battery, the battery in the long-term use process, battery capacity, etc. will be reduced with the use of time, as the battery, what is the relationship between the number of cycles and the battery?
The number of cycles refers to the time and number of times the battery is in use, in other words, then the battery is full, and then the battery is replaced, and then full again, in the discharge, and then in the full cycle repeatedly. For power batteries, a complete charging and discharging process is a cycle, according to this thing, the battery is the number of cycles.
According to the service life of ternary lithium batteries, the life of the battery is in the 1500 to 2000 cycles, and this number of cycles, will become less as the battery in the process of use, the cycle number is reduced, meaning that the life of the battery is also decreasing, in the process of use, as the number of cycles of the battery is decreasing, then it also means that the lithium battery will occur irreversible electrochemical reaction inside the battery resulting in capacity decline.
In summary: the number of cycles of lithium battery life is based on the quality of the battery and battery materials, the number of cycles of lithium batteries and the life of the battery is inextricably linked to each other. Every time you complete a cycle, the capacity of the battery will be reduced a little, and the service life of the battery will be reduced.
