What is battery cycle count? How long can the battery last?

Many car owners are very concerned about the range of their vehicle, but besides range, the life of the battery is also a great concern to them. So, how many kilometers can the Z03's battery last before it is scrapped? And how many years can it last?

Many people incorrectly think that cycling once means charging or discharging once.Battery recycling In fact, Cycle 1 is the process of fully charging a battery once and then discharging the fully charged battery, this process is called Cycle 1.

When a battery completes a full charge cycle, i.e.,cylindrical cell assembly machine the battery uses 100% of its charge and then is fully charged again at 100%, it is considered a charge cycle, at which point the number of cycles of the battery is increased by 1.

It should be emphasized that the charging and discharging process is cumulative.battery making machine For example, if 70% of the charge is used on the first day, and 30% on the second day, then the cumulative total is 100%. If you charge the battery to 50% after using it, and then charge it to 50% the next day, this is also considered a charging cycle, and the number of times the battery has been cycled is only counted as 1 time, not 2 times as 2 charging cycles.

So why do batteries "lose their life"?

After understanding the number of battery cycles, let's take a look at the factors that affect battery life.

In fact, the number of times of charging and discharging, the environment, weather, road conditions, driving habits, etc. will have an impact on the battery life. Of these, the number of cycles of charging and discharging has the greatest impact on battery life. With the completion of each charging cycle, the capacity of the battery will be slightly reduced.

According to the national standard GB T 31484-2015 (Cycle Life Requirements and Test Methods for Power Storage Batteries for Electric Vehicles), the power battery's cell and module should be able to maintain not less than 90% of the capacity of the initial state after 500 complete cycles; and after 1,000 complete cycles, it should be able to maintain not less than 80% of the capacity. This is the basic requirement for power battery life.

So, how to make the battery more "durable"?

In addition to the number of charging cycles, everyone's car environment and driving style are different, and these objective factors will also be reflected in the life of the battery. Although these objective factors cannot be changed immediately, it is relatively easy to avoid the following operations that are harmful to the battery.

First, check your tire pressure in a timely manner to ensure that it stays within a reasonable range. This saves energy and extends the life of the tires.

Secondly, if the vehicle is in a parked state, it is recommended to check the power level regularly to avoid battery loss due to prolonged idling.

In addition, it is important to avoid driving the vehicle for a long period of time with low power, and never discharge the battery completely to 0.

When the vehicle is traveling over roads with deep water, it should be operated with caution to avoid excessive touching of water leading to short circuit, leakage or damage to the battery.

Similarly, when the vehicle is traveling through mud, potholes and other special road surfaces, it should also be operated carefully to avoid chassis collision resulting in scratches or damage to the power battery.

Good driving habits can not only make the battery more durable, but also extend the range to a certain extent. In addition, smooth driving can also enhance driving comfort, making every journey more enjoyable.
