Batterie échangeable à chaud 507090-3S

Hot-swappable Battery3S Structure Overview

Engineers design the 507090 Hot-swappable Battery (3S configuration) using a modular pouch-cell assembly process. First, they arrange three LiPo cells in a series connection layout to form a stable voltage structure. Then, technicians align each pouch cell with controlled spacing to reduce mechanical stress during operation. Meanwhile, insulation sheets are inserted between cells to prevent internal abrasion and electrical interference. After alignment, the pack proceeds into welding, integration, and enclosure preparation stages. The overall structure is formed through a controlled stacking and fixing process.

Cell Material System and Electrochemical Design

Manufacturers construct each pouch cell using lithium metal oxide cathodes coated on aluminum foil, while graphite-based anodes are applied on copper foil. In addition, a microporous polymer separator is placed between electrodes to allow lithium-ion transport while preventing direct contact. Furthermore, the electrolyte consists of lithium salts dissolved in organic carbonate solvents, and moisture is tightly controlled during filling. Meanwhile, the aluminum-plastic laminated film acts as the outer shell, replacing rigid casing with a flexible sealing structure.

Pack Assembly and Electrical Integration

Technicians begin by matching cell capacity, internal resistance, and voltage consistency before assembly. Next, they connect the cells in a 3S series configuration using nickel tabs through controlled spot welding. After that, a protection circuit module (PCM/BMS) is integrated to manage overcharge, over-discharge, and short-circuit conditions. Meanwhile, wiring harnesses are routed with insulation sleeves to maintain electrical safety and reduce resistance loss. In addition, continuity testing is performed to confirm stable current pathways across the entire pack.

Formation Testing and Compliance Standards

Engineers perform initial charge-discharge cycling to activate electrochemical balance across all cells. Afterwards, aging tests are conducted to evaluate voltage stability and internal resistance drift. Finally, insulation testing, weld inspection, and electrical performance verification are completed. Throughout manufacturing, the lithium polymer battery pack follows IEC 62133 and UN38.3 standards, ensuring structural reliability, electrical safety, and transportation compliance.
