What is the cause of electric vehicle battery is not durable

　　With the development of electric vehicles, the current electric vehicle has now got rid of the embarrassing situation of unreasonable power charging like an old electric vehicle, especially for some special occupations, such as the delivery staff and takeaway, waiting for electric vehicles to charge them It is not cost -effective, so a variety of cars fast charging cabinets and electric shift cabinets have begun to spread. However, some electric car owners have said that they can only be charged for three times. When you go to the repair shop to repair, the master said directly that the battery was invalidated. What is the reason?

　　The reason is actually very simple, mainly the pot of fast charging stations! You know, the working principle of the fast charging station is high -voltage and large -current veins charging, which is often said to be large -current charging. As far as ordinary 48 volt electric vehicles are concerned, the electric vehicle current itself is constant, and in order to solve 12 hours of charging in two hours, it will often increase the current. Only the impact on the vehicle that is irreversible will present the above problems. Strong current charging can cause the following two effects of the following two irreversible effects on electric vehicles.

　　First, the battery pole plate aging, and the large current charging will cause the temperature of the battery to become very high. Under such conditions, the hydrochloric acid in the battery will form lead sulfate due to volatilization, which will shorten the service life of the electric vehicle battery. The battery life continues to decline, and the battery is hot and out of control, causing drums. Therefore, in this charging condition, the oxidation reaction will be generated. It simply causes the battery to direct drums.

　　Second, because the battery itself is not closed. Nowadays, the problem of battery existence is also an accident that will occur. The battery is not available and the current is too large, which makes the battery directly abandoned. Therefore, the fast charging station is also a detection station for battery quality! There are also many battery manufacturers made of batteries made of power -disassembly. We can use the new A -grade core core, and we will never engage in the set!

　　Of course, when we buy and use electric vehicles, we must buy a manufacturer to produce electric vehicles with qualified signs. Try not to use the fast charging device as much as possible. You can go to some stores with electrical qualifications for battery replacement. This is also a protection for electric vehicles.
