Analysis of the gap between China's power battery and the international

Compared with the international market, the battery level gap is too big. Nearly 90% of China's battery companies are still assembled by hand. Compared with foreign countries, technology is too backward. It is understood that at present, there are no more than five people in China who have mastered the core technology of vehicle battery research and development.

Regardless of the type of battery, at present, China's technology is still relatively backward. Compared with lithium batteries, the production technology of lead-acid batteries is relatively mature, and the waste recycling technology generated during the production process is also easier to control. Therefore, the question of who is more environmentally friendly should not be compared, but depends on the degree of perfection of technology.

The ternary lithium battery produced by Panasonic has a significant advantage in charge and discharge performance and endurance, but it is less stable than lithium iron phosphate battery. Tesla used Panasonic's ternary lithium battery because Panasonic owns Tesla's shares, which means they are not supplier relations. It is inaccurate to define which battery is more suitable for electric vehicles. The key is to see whether the vehicle is pursuing endurance or safety.

At present, China's current standards for car battery production are very small. Most of the batteries produced by enterprises do not meet the standards . If they do not meet the standards , they will not be recognized by the manufacturers, and they cannot be calculated in the car battery capacity. Because the entry barriers for lithium battery companies are very low, and many companies have taken a fancy to the government's support for electric vehicles, everyone is staring at this "Dang Tang meat", but the technical requirements of the car battery in the battery field are the most stringent . Not anyone who wants to do it can do it.

Analysis of the gap between China's power battery and the international

Wang Zidong, director of the National 863 Electric Vehicle Major Special Power Battery Test Center, believes that in the early stage of the development of electric vehicles, we should treat everything rationally and not blindly follow suit.

An electric car made by 100,000 US dollars, the technology is good, and Tesla has nothing unusual. I think some media are somewhat biased about Tesla's propaganda. International car batteries have relevant testing standards for safety performance, but Tesla does not. At present, many people are saying that Tesla's car has not had any security incidents. This does not mean that there are no security risks. The media should not judge prematurely and speak according to standards.

In the field of new energy, the government can only grasp the policy of the big policy, do not intervene in everything, and must not engage in "flowering everywhere", must adhere to the "four haves", that is, there are restrictions, encouragement, standards, and penalties, and truly make China's electric The automotive industry is getting bigger and better.

Why we recommend iPhone 8 Battery Replacement with TI IC?

1. TI IC is original method for iPhone battery.

2. Charging more faster, less fever heat to save battery life.

3. Accurate battery power monitoring.

4. Keep stable performance and controlable temperture.

5. The battery with TI IC more safe, charge more faster, lasts longer life.
