How to calculate the number of cycle charge of the electric battery and how long it lasts

What is the most important concern we usually have when we buy an electric car or replace the battery with a new one? The salesperson will usually tell you that the electric battery can last two to three years. However,Battery recycling this statement is not accurate. Especially for the boys who run takeaways, they know this very well. For example, a new set of batteries, whether you use a regular battery or a graphene battery, will only last a little over a year at most, and will need to be replaced with a new one when it goes out.

What you may not realize is that each set of batteries has its own number of life cycle charges. The two largest brands of electric batteries in the country currently have between 400 and 500 charge/discharge cycles claimed by the manufacturers.cylindrical cell assembly machine This does not mean that each charge is considered one. Many people have this misunderstanding, so often people charge their batteries after they are depleted, until the battery power drops to about 30%. This is a misunderstanding of the number of 400 to 500 charge cycles.

How is the so-called number of charging cycles calculated? Let's say, for example, we always ask our customers to keep the battery level at about 30% remaining for each charge. Then the process from 30% to full is counted as 0.7 charging cycles and cannot be counted as a single charge.battery making machine The next time you recharge, start charging from 70% and charge it until it's full, which is 0.3 times charging, and the two times are added together to equal 100%, which is a cycle of charging. Some of you may say, in that case, I can charge every day, but what you don't know is that every battery has a memory function. Each time you charge, the battery will retain about 30% of its charge before the next charge. This process is good for the battery, minimizing battery loss and protecting the battery. If you wait until the charge is low every time before charging, then the battery is already in deficit at this time, which will cause damage to the battery in the long term, resulting in an intolerant battery to run.

From the point of view of the number of such cycle charging, the larger the capacity of the battery, the fewer the number of times of charging, so that his battery life will be longer. So how is our battery life calculated? Let's say, an electric car can run 70km per charge, multiplied by the manufacturer's claim of 400 times charging, that is to say, this group of batteries can run 28,000km, the battery will be scrapped. In the process of our use, we may not be able to run 28000km, this battery will be scrapped. This has a lot to do with our charging and riding habits. Even I myself can't do the charging habit correctly every time. So the total kilometers will be discounted.
