Why is the battery quality of electric vehicles generally not as good as before?

The truth! Why is the battery quality of electric vehicles generally not as good as before? In the occupation of electric vehicles, you can often hear the complaints of many electric vehicle occupation companies and users: The current batteries are not good. Once the batteries can run for about three years, now there is only one The life span of years is even shorter. They even summed up several reasons, such as the acquisition of small-brand factories by surrounding large factories, which led to unstable quality; some people said that battery manufacturers cut corners in order to save money. Some people say that the factory is very poor. Are these reasons the quality of the batteries really down? Why are electric vehicles improving in all aspects, but the batteries are not? Fact 1: The high configuration of electric vehicles has led to the increase in the pressure on batteries of today's electric vehicles We are better equipped than ever before, pursuing higher power, faster speed, more power, and then more energy. In addition, the tires of electric vehicles are thicker than before. For example, vacuum tires are used for motors. All these factors lead to more power consumption. In addition, electric vehicles have also added a large number of electrical equipment, such as anti-theft devices, remote start, driving lights, music players, bucket lights, etc., which increase the load of the battery and affect the function of the battery. Fact 2: The cadmium-free process of the battery significantly reduces the battery function. What are the benefits of cadmium to the battery? Adding cadmium can eliminate grid cracks; cadmium-containing alloys have a long service life, dense crystals, and corrosion resistance. Cadmium has a high hydrogen potential and is difficult to separate. Simply put, the addition of cadmium can increase the conductivity of the battery, reduce the internal resistance of the battery, increase the discharge voltage of the battery, resist high and low temperatures, have good charge and discharge performance, and have a long service life. The Ministry of Industry and Information Technology (Ministry of Industry and Information Technology), the Ministry of Environmental Protection (mep) and the professional association of my country have clearly stipulated that the processing capacity of lead batteries must have lead and cadmium content higher than 0.002% or some arsenic content higher than 0.1%. It should be cancelled on the 31st. Various battery companies strictly abide by national regulations. After 2014, batteries that meet the national standards of products are under strict control of the content of cadmium and arsenic. Even in some companies, there is no cadmium battery at all. Objectively speaking, the battery without cadmium will lead to life. Loss and certain stability, but in the long-term development: it is not that the battery is not good, but the battery is more environmentally friendly! The third stage: the speed of electric vehicles is getting faster and faster, and the motor power is also increasing. It is well known that in the past few years , The electric motor power on the market is relatively small, with a primary power of 250W and a primary power of 500W. In recent years, in pursuit of faster speeds, the motor power of electric vehicles has continued to increase. The minimum power is basically 500W. 800W motors and 1200W motors are also common. It is true that the higher the motor power, the higher the motor speed, which will speed up the battery life. Fact 4: Electric cars are getting heavier and more power-consuming. Before 2014, the simplicity of the first electric cars on the market demanded more and more comfort in terms of comfort. Now, the market share of luxury electric vehicles is getting bigger and bigger. The weight of luxury electric vehicles has increased significantly, and the power consumption has increased. Reality 5: Bad charging habits affect battery function. As long as there are the following bad charging habits, for example, the battery is out of power for a long time, using a fast charging station, charging for a long time or using a bad charger, etc., the battery function will be affected , In severe cases, the battery leaks or the drum is deformed. The temperature drops in winter and the temperature in summer reduces the battery function. Therefore, the demand for a 25°C environment is preferably the remaining 30% of the electricity bill in the electric vehicle battery! Fact 6: Bad riding habits will affect the battery function and daily cycling Habits also have a certain impact on the battery life of electric vehicles. Even when driving and braking less, it is the best protection for the battery. When the electric vehicle is started with a foot pedal, it should be started with a foot pedal to avoid damage to the battery due to excessive discharge current. Slow down on rough roads and recharge the battery when it runs out. Don't run out of electricity. Fact 7: The market is full of unwritten rules of innovative batteries. There are many fake batteries on the market, especially in the third and fourth-tier areas. Unscrupulous vendors recycle waste batteries with newer appearances at low prices, recharge, repair, and innovate the outer casing, then pack them from scratch and sneak into chain stores. This is one of the most important reasons why many people change their batteries once a year. In addition to some unqualified batteries processed by irresponsible manufacturers, the function of the batteries is also affected. Most batteries are not worse than before. When the battery is in use, we must take good care of it. At the same time, we must pay attention to charging and discharging, pay attention to the use of conventional chargers, so as to effectively protect the battery. Although the battery life is not as long as before, it can be maintained in two to three years. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
