CR2320 battery.Adverse effects of fast charging of electric vehicles on batteries

　　When we buy a new energy vehicle, the most concerned topic is its cruising range, and the cruising range is closely related to the battery. Careful friends will find that when purchasing an electric vehicle, they will see a fast charging interface and The slow charging interface, that is, in terms of charging time, has a slow charging time and a fast charging time. Many electric vehicles can charge enough power in less than half an hour. So, what negative impact does fast charging of electric vehicles have on the battery? Why? First of all, we all know that the working principles of fast charging and slow charging of electric vehicles are different. Fast charging mainly uses DC voltage for charging. In this case, the DC voltage is greater than the actual battery voltage, and a large amount of current ions also The flow will flow from the positive electrode to the negative electrode of the battery at a very fast and very efficient speed, thus completing the process of fast charging. That is to say, in the case of long-term fast charging, the actual voltage that the battery withstands is very high. In such a high-voltage state, it will definitely be affected. Secondly, if you choose fast charging for a long time or frequently, the current or voltage requirements on the battery will be very high, the temperature of the battery pack will also increase, and the battery will decay very quickly under long-term high temperature. A 10-year-old battery may only be used for seven years or less if fast charging is used for a long time. As a relatively high-cost accessory for electric vehicles, batteries must also be paid attention to in terms of charging and maintenance. Of course, the choice between fast charging and slow charging of electric vehicles should be based on our daily needs. When time is tight and we are in a hurry to use the car, we can only choose fast charging. However, when we use cars in normal life, we still choose slow charging. , protect the battery within the range that the battery can withstand and increase its service life. All in all, fast charging of electric vehicles is harmful to the battery. During daily use, we try to keep the battery in a relatively mild state, receive normal current and voltage, and have a stable temperature, so as to extend its service life and reduce unnecessary Loss.
