What is a 402030 polymer battery? Power 402030 polymer battery technology

　　What is a 402030 polymer battery? Power 402030 polymer battery technology. 402030 polymer battery generally refers to combined batteries. 402030 polymer battery is realized in two ways. One is through laser welding or ultrasonic welding or pulse welding. This is a commonly used welding method. It has the advantage of better reliability but is not easy to replace. The second is contact through elastic metal sheets. As the division of labor in production becomes more and more obvious, the power 402030 polymer battery industry has gradually taken off and achieved rapid development.

　　What is a 402030 polymer battery?

　　402030 polymer battery generally refers to packaging, encapsulation and assembly. For example, if two batteries are connected in series and formed into a specific shape according to customer requirements, we call it a pack. In the Pack industry, batteries that are not assembled and can be used directly are often called batteries, while finished batteries that are connected to a PCM board and have charging and discharging functions are called batteries.

　　The PACK grouping process is a key step in the production of power 402030 polymer batterys, and its importance has become increasingly obvious as the electric vehicle market continues to expand. At present, automotive power batteries basically consist of the following systems: battery modules, battery management systems, thermal management systems, electrical and mechanical systems.

　　402030 polymer battery is now mainly concentrated in lithium 402030 polymer battery factories. They all have their own PACK structural design, PACK electronic design and PACK production workshops. They can carry out independent development and design according to customer needs, through battery plans, battery specifications, and battery samples. After the customer's PACK lithium battery customization needs are confirmed, the PACK production line in the PACK workshop will be produced and processed, and the products will be shipped after passing the quality inspection.

　　Introduction to power 402030 polymer battery process

　　1. Assembly process

　　The assembly process of PACK is actually somewhat similar to the engine assembly process of traditional fuel vehicles. The five major systems are connected together through bolts, nuts, cable ties, clamps, wire harness nails and other connecting parts to form an assembly.

　　2. Air tightness testing process

　　The power 402030 polymer battery is generally installed under the seat or trunk of a new energy vehicle and is in direct contact with the outside world. When high-voltage electricity comes into contact with water, you can imagine the consequences with common sense. Therefore, when new energy vehicles wade into water, the 402030 polymer battery needs to have good sealing properties.

　　3. Software flashing process

　　The software flashing process is to flash the BMS control strategy into the CMU and BMU in the BMS in the form of code, so that the battery status information data collected during battery testing and use can be processed and analyzed by the electronic control unit. Then based on the analysis results, control instructions are issued to relevant functional modules in the system, and finally the information is transmitted to the outside world.

　　4. Electrical performance testing process

　　The electrical performance testing process is a testing process that must be done after the above three processes are completed, that is, before the product comes off the production line. Including insulation testing, charging status testing, fast and slow charging tests, etc.

　　402030 polymer battery development prospects

　　The global power 402030 polymer battery market is mainly monopolized by Japan, South Korea and China, whose power battery production capacity accounts for more than 95% of the world. Calculated according to the goals of battery energy density of 300Wh/kg and Pack energy density of 260Wh/kg, the integration efficiency of the Pack system must reach 85%, while the current integration efficiency of the Passenger Car Pack is generally around 65%, which means that the integration efficiency of the Pack system must be 85%. Efficiency needs to be greatly improved to achieve the goal.

　　To improve the integration efficiency of the Pack, there are two feasible ways. One is to optimize the internal structural design of the Pack, greatly reduce the number of components inside the Pack, and integrate more components and functions into the modules and cabinets, thus reducing the Weight; the other is to use lightweight materials, such as using aluminum profiles or composite materials instead of high-strength steel, using plastic parts instead of metal parts, etc., which can also reduce weight.

　　As the main battery used in new energy vehicles, power batteries will usher in a period of golden development opportunities driven by policies. The power 402030 polymer battery industry will also get more development opportunities under the good situation of power batteries. Moreover, with the continuous updating and breakthrough of technology and the continuous innovation and exploration of business models, the power 402030 polymer battery industry will also usher in faster growth driven by new technologies and new models.

　　Power 402030 polymer battery is a relatively technology-intensive industry. In the next five years, the growth rate of the power 402030 polymer battery industry will remain at around 30%. By 2023, the global power 402030 polymer battery market will reach US$186.3 billion.
