507090-3S Hot-swappable Battery

Hot-swappable Battery3S Structure Overview

The 507090 Hot-swappable Battery (3S configuration) is designed by engineers through a modular pouch-cell assembly process. To create a stable voltage structure, they first connect three LiPo cells in a series connection design. Then, technicians match each pouch cell with regulated spacing to minimize mechanical stress in the course of operation. In the meantime, insulation sheets are placed between cells to avoid internal abrasion and electrical interference. Once aligned, the pack moves into the welding, integration, and enclosure preparation phases. The general framework is created by a regulated process of stacking and fixing.

Cell Material System and Electrochemical Design

Each pouch cell is built by manufacturers with lithium metal oxide cathodes on aluminum foil and graphite-based anodes on copper foil. Moreover, a microporous polymer separator is inserted between electrodes to enable the movement of lithium ions but not direct contact. Moreover, the electrolyte is composed of lithium salts dissolved in organic carbonate solvents, and moisture is strictly regulated during filling. In the meantime, the aluminum-plastic laminated film serves as the outer shell, which substitutes the rigid casing with a flexible sealing structure.

Pack Assembly and Electrical Integration

Technicians start by matching cell capacity, internal resistance, and voltage consistency, and then assemble. They then proceed to weld the cells in a 3S series arrangement with nickel tabs by controlled spot welding. A protection circuit module (PCM/BMS) is then added to control overcharge, over-discharge, and short-circuit. In the meantime, wiring harnesses are insulated by using insulation sleeves to ensure electrical safety and minimize resistance loss. Continuity testing is also done to ensure consistent current pathways throughout the pack.

Formation Testing and Compliance Standards

Initial charge-discharge cycling is performed by the engineers to initiate electrochemical balance in all the cells. Subsequently, aging tests are done to assess voltage stability and internal resistance drift. Lastly, insulation testing, weld inspection, and electrical performance verification are done. During the manufacturing process, the lithium polymer battery pack is based on IEC 62133 and UN38.3 standards, which guarantee structural stability, electrical safety, and transportation.

Product Features

• Medical-grade safety: It will use a polymer soft-pack design with no metal casing, which will only swell instead of exploding even in extreme circumstances, which offers the utmost safety to medical equipment.
• Constant and predictable power output: Intelligent protection circuitry is built in to monitor the charging and discharging process in real time and maintain a constant and predictable voltage output, ensuring proper and reliable diagnostic and treatment information.
• Flexible adaptation and space flexibility: The soft-pack design can be customized in various shapes and sizes, easily embedding into various compact medical devices, providing greater freedom in product design.
• High energy density: It has a greater capacity and lower weight than traditional liquid batteries of the same size, and is useful in increasing the life of devices and decreasing their carrying weight.
• Strict testing and thorough certifications: It is certified by various international authoritative certifications such as KC, CB, UN38.3, TUV, CQC, MSDS, CE, and IEC62133, and its quality can stand the test of the global market.
• Extended cycle life and constant reliability: A cycle life of more than 500 cycles and no memory effect means that it will greatly reduce the frequency of replacement and the cost of ownership in the overall lifespan of the product.
• Ready to use: Right out of the box: Factory voltage is 12.0V, so no pre-charge is required, and more efficient equipment can be deployed.
