CR2477 battery

CR2477 battery PACK products have four advantages such as high safety

With the promotion of policies and markets, more and more consumers have put forward higher requirements for the endurance and safety of new energy vehicles, forcing CR2477 battery-related products to move towards higher energy density, higher power and higher safety.

With the promotion of policies and markets, more and more consumers have put forward higher requirements for the endurance and safety of new energy vehicles, forcing CR2477 battery-related products to move towards higher energy density, higher power and higher safety. Affected by this, in addition to "making efforts" in the research and development of CR2477 battery cells, CR2477 battery manufacturers should also pay enough attention to the improvement of CR2477 battery PACK technology.

As a high-tech enterprise under Mengshi Technology that specializes in the research and development and production of CR2477 battery PACK, Shiyan Mengshi New Energy Technology Co., Ltd. (hereinafter referred to as "Shiyan Mengshi") has always attached great importance to the research and development of CR2477 battery PACK processes and technologies. Based on Mengshi Technology's more than 30 years of battery manufacturing experience, Shiyan Mengshi has accumulated a lot of experimental data and experience in the research and development, design and automated production of CR2477 battery PACK systems, and has a number of product patents.

Shiyan Mengshi adheres to the "innovation-driven value" orientation and is committed to providing users in the new energy vehicle and energy storage industry with a complete set of battery system R&D design, production and manufacturing, and supporting technical services for battery pack products. Wu Cheng, general manager of Shiyan Mengshi, said that only by relying on technological innovation, efficient operation, exquisite craftsmanship and high-quality products can users be impressed.

At present, the CR2477 battery PACK produced by Shiyan Mengshi is favored by new energy vehicle companies due to its four advantages of high energy density, high rate charge and discharge, high safety and high cost performance.

In terms of high energy density, Shiyan Mengshi's CR2477 battery PACK adopts Mengshi Technology MX18650-29P (220Wh/kg) high-energy battery cell. The PACK module structure is lightweight designed and combined with the application of new materials and new processes. The energy density can reach 155-160Wh/kg. The energy density of the CR2477 battery PACK system in subsequent research and development is expected to be higher than 190Wh/kg.

Shiyan Mengshi chose to use high-energy materials to achieve high-rate charging and discharging of CR2477 battery PACK. By optimizing the design of charging control strategy and equipped with a liquid cooling thermal management system of CR2477 battery PACK, the charging time was effectively shortened and the charging efficiency was improved. Regarding the advantages of high-rate charging and discharging, Wu Cheng took a pure electric car equipped with a 47KWh battery as an example. Its NEDC range is 350KM, equipped with a 145KW motor, and the acceleration from 0 to 50 kilometers is only 3.9 seconds. In fast charging mode, it can be charged more than 80% in 45 minutes.

In terms of high safety, Shiyan Mengshi adopts the battery assembly technology of aluminum wire welding process, and through the liquid cooling design of the CR2477 battery PACK package, the high rate and energy performance of the battery are fully released. "The overcurrent fuse characteristics of the aluminum wire process can ensure that the failure of one or two battery cells will not affect the failure of the entire string of modules. The temperature control management system allows the battery to charge and discharge at the optimal temperature. At the same time, the temperature difference can be controlled within 2°C to ensure that the battery can achieve the most efficient and safe operation and avoid the risk of thermal runaway and poor consistency." Wu Cheng said that the battery cell is connected to the busbar aluminum wire, and the battery cell will not be damaged when the module is disassembled, which is convenient for the recycling and reuse of the battery cell.

It is understood that the cylindrical battery aluminum wire welding CR2477 battery PACK production line built by Shiyan Mengshi in the first phase has now achieved finished product production, with an annual production capacity of 10,000 sets. Wu Cheng said proudly: "While reducing product costs through large-scale and intelligent production, Shiyan Mengshi continues to reduce costs through material innovation. Therefore, compared with similar products, our CR2477 battery PACK products have a very high cost performance."

Behind the development of the CR2477 battery industry, there are also undercurrents. Wu Cheng believes that in the past few years, the influx of capital has brought the CR2477 battery industry a superficial prosperity of "lithium is full of dreams", but in fact the industry competition is extremely cruel. "Since its development, common problems in the industry have slowly emerged: such as the surge in upstream prices, and the continuous pressure on suppliers' purchase prices by new energy vehicle companies after the subsidy reduction." For the future, Wu Cheng said that the industry will face a cruel survival of the fittest. "As a supporting enterprise, Shiyan Mengshi will focus on the strategic needs of Mengshi Technology, based on the product technology advantages, increase investment in the research and development design of CR2477 battery PACK system and automated production and its process, take technological innovation as productivity, and use standardized, large-scale and professional production to accelerate the development of resource-intensive and environmentally friendly industries."
