What are the culprits that damage the batteries of electric vehicles?

As electric vehicles are the most common means of transportation around the people, the use and maintenance of batteries has also become a major topic. So, what is it that damages electric vehicle batteries? Let's take a look at the culprits that damage electric vehicle batteries! 　　 One-yuan fast charge It is understood that standard electric vehicle batteries generally use three-stage chargers with a maximum charging voltage. It should be 56V and the current is about 2.5A. The so-called fast charging is to increase the voltage to about 60V while increasing the current to 7 to 13A. Therefore, fast charging is a charging method that is realized at the cost of damaging the battery.　　 One-yuan fast charge, no barriers to entry, no related technologies, or even 'three noes' products, there are serious security risks, and it is difficult to defend rights when problems occur. Here, the author sincerely reminds consumers to use one-yuan fast charging with caution and try to bring their own standard chargers to charge electric vehicles. In addition, for fast charging stations for electric vehicles, it was originally for the convenience of the public, but it is not easy to achieve real convenience. Do not think about making a quick money and leave. Improving quality and standardizing behavior is the right way. So, in addition to the common 'one-yuan fast charge' on the roadside, what other charging components or charging behaviors are also not conducive to the maintenance and use of electric vehicle batteries? 　　 different brand chargers electric vehicle batteries need to be used for a long time, the quality of the charger It plays a vital role. Now the normal life of the battery is three years. The main reason for the early end of the life is the poor quality of the charger. It turns out that inferior chargers can cause undercharge or overcharge, which will kill the battery. Insufficient charging will cause the lead sulfate of the positive and negative plates to not be completely converted into spongy lead and lead dioxide, which will make the battery discharge capacity insufficient. If the battery is insufficiently charged for a long time, it will cause the lead sulfate crystals to become larger, vulcanize the lead plates and shorten the battery life. Overcharging of the charger causes the internal resistance of the battery to increase, the battery swells, and even causes the electric vehicle to charge spontaneously and cause a fire. Electric Vehicle Mileage Increaser In the past two years, an artifact called the Electric Vehicle Mileage Increaser turned out. Its working principle is to use the controller to sense the line voltage to trick the controller and make it continue to discharge the remaining power of the battery. Increase mileage. It turns out that electric vehicles are generally equipped with under-voltage protection devices to protect the battery from over-discharge. When the battery power is under-voltage, the electric vehicle can no longer drive, and the 'mileage increaser' is to reduce the 10% of the electricity. Give it to use. Long-term discharge like this will cause fatal damage to the battery! Previous: How to judge whether the electric vehicle controller is short-circuited or the motor has entered water?
