Why not increase the current to reduce the battery charging time

I wonder if there are users who will charge by increasing the current in order to fill up the electricity earlier or when they need to use it. This not only reduces the charging time, but also ensures full power without reducing the capacity. So, is this good?

Asahi sent battery technicians to tell you, no! And it's very bad. Why? It turned out that each electric vehicle battery has a certain specification in the production process, manufacturers according to the specifications to produce, various data have been fixed. Because the charging current is relatively small, the battery's charging time is relatively long, about eight hours, so go home at night and charge it for one night, and use it the next day. However, some people often forget to charge at night and don't have enough power for the day.

Therefore, we want to overcome this problem through high current. However, it is counterproductive. After the current increases, not only can the electric car battery reach the charging capacity, but it will cause the battery to heat up very quickly, generate a lot of heat and gas, and cause the active material inside the battery to fall off, which will affect the service life of the electric car battery.

Not only that, but they also point to polarization when charged with a large current. So what is polarization? Polarization is a phenomenon that occurs in secondary charging. It is mainly when the battery of an electric vehicle is charged and discharged, and the positive and negative poles undergo polarization reactions. Both the electric position moves, which is very harmful to the battery. In addition, in the process of charging an electric car battery, the concentration polarization will be more obvious. After stopping charging, the diffusion will exacerbate its disappearance. That is, although it is full of electricity, it will not be used as long as slow charging.

In addition, professionals also emphasize that increasing current charging will also lead to air and temperature rise, and water decomposition is serious, resulting in a large number of active substances falling off, but also lead to insufficient internal chemical reactions in the battery, the result must be shortened battery life.

So, is this the case with the Asahi battery? In fact, even the high quality electric vehicle batteries such as Xupai batteries, if they are not carefully maintained, these undesirable phenomena will occur. Therefore, special attention should be paid to maintenance.

As a leading brand of high-quality electric vehicle batteries, Xupai batteries have a great deal of credit in the development of electric vehicles. They not only promote the development of the electric vehicle battery industry in China, but also inject fresh factors into the industry. Over the years, the Xupai battery manufacturers have always adhered to the concept of inheriting the Xupai culture, appreciating the brand model, constantly innovating, and constantly absorbing advanced technologies and techniques. After many years of development, they have established a relatively complete market system. Can provide consumers with more comprehensive and faster product services.

From the above explanation, it can be seen that the maintenance of the battery is very important, especially in the process of charging and discharging, it is not too fast to charge and discharge according to the manufacturer's instructions, so as to ensure the service effect and life of the battery, otherwise it will only damage the battery. Waste more money.
