Four advantages of lithium battery PACK products
Text label: Lithium battery PACK
With the promotion of policies and the market, more and more consumers have put forward higher requirements for the durability and safety of new energy vehicles. Lithium battery related products are developing in the direction of higher energy density, higher power and higher safety. Therefore, in addition to the research and development of lithium battery cells in lithium battery systems, the improvement of lithium battery pack technology should also attract more attention.
As a high-tech enterprise specializing in the research and development and production of lithium battery PACK, Guanlida Electronics Co., Ltd. (hereinafter referred to as "GLIDA") has always attached great importance to the research and development of lithium battery PACK technology and technology. . Based on more than 30 years of industry battery manufacturing experience, Crown Power has accumulated a large amount of experimental data and experience in the research, design and automated production of lithium battery pack packaging systems, and has a number of product patents.
Under the guidance of "innovation-driven value", Crown Power is committed to providing a complete set of battery system R&D, design, production, manufacturing and battery packaging products for users in the new energy vehicle and energy storage industry. The general manager of Guanlida Technology Group said that only technological innovation based on efficient operation, with exquisite craftsmanship and high-quality products, will leave a deep impression on users.
At present, the lithium battery pack produced by Crown Lida Battery is favored by new energy automobile companies for its four major advantages: high energy density, fast charge and discharge speed, high safety, and high cost performance.
In terms of high energy density, Crown Power`s lithium battery PACK uses MX18650-29P (220Wh/kg) high-energy battery. The PACK module structure design is light and handy, and combines new materials and new process applications. 155-160Wh/kg. In subsequent research and development, the energy density of the lithium battery pack packaging system is expected to be higher than 190Wh/kg.
Crown Lida battery chooses to use high-energy materials to achieve high-rate charging and discharging of lithium battery packs. Through the optimized design of the charging control strategy, and equipped with the liquid cooling thermal management system of the lithium battery pack, the charging time is effectively shortened and the charging efficiency is improved. Because of the advantages of high-rate charging and discharging, take a pure electric vehicle with a 47KWh battery as an example. Its northeast DC range is 350 kilometers, equipped with a 145KW motor, 0≤50 km acceleration in only 3.9 seconds, and it can charge more than 80% in 45 minutes in the fast charging mode.
In terms of high safety, the corona battery adopts the battery composition technology of aluminum wire welding, and the package of the lithium battery is designed with liquid cooling to ensure the full release of the battery's high power and high energy performance. "The over-current melting characteristics of the aluminum wire process ensure one or two cores of the aluminum wire. Failure will not affect the failure of the entire module. The temperature management system allows the battery to be charged and discharged at the optimal temperature. At the same time, the temperature difference can be controlled within Within 2°C to ensure the most effective and safe operation of the battery and avoid the risk of thermal runaway and consistency.
The results show that the core is connected with the confluence aluminum wire, and the core is not damaged when the module is disassembled, which is convenient for the recovery and reuse of the core. It is understood that the cylindrical battery aluminum wire welding lithium battery pack production line built in the first phase of Guanlida Battery has now achieved offline production of finished products, with an annual production capacity of up to 10,000 units. He proudly said: "While reducing product costs through large-scale intelligent production, Crown Lida batteries are still being adopted.
Reduce costs through material innovation, so compared with similar products, our lithium battery products have a very high cost performance. "Behind the development of the lithium battery industry, undercurrents are also increasing sharply. In recent years, the influx of capital has brought a kind of superficial prosperity to the lithium battery industry that "Li wants to be very full," but in fact, industry competition is extremely cruel. "So far, common problems in the industry are slowly emerging. If upstream prices soar and subsidies fall, new energy vehicle companies will continue to depress suppliers' purchase prices."
For the future, this industry will face the cruel challenge of survival of the fittest. "As a supporting enterprise, Guanlida Technology Group will increase the research and development, design and automation of lithium battery pack packaging systems based on the strategic needs of new technologies and the technological advantages of products.
Technological investment with technological innovation as productivity will accelerate the development of resource-intensive, environment-friendly, standardized, large-scale, and specialized industries.
