V. Aging Test Specification

Equipment Introduction: The BTS100-100-8CH system is a high-precision charging and discharging equipment designed and developed specifically for testing medium and low power battery packs. It is mainly used for battery pack capacity testing, shipment inspection, endurance testing, and product design verification. The system adopts a design architecture with recyclable energy, and the discharge energy of the battery pack is recycled and reused, achieving the effects of energy conservation, environmental protection, and low thermal energy output.

VI. Packaging Line Specification

Equipment introduction: This equipment includes a sealing machine, a strapping machine, a weighing machine, etc; After manual loading, labeling and nameplate pasting, LQC full inspection is completed, and the packaging box automatically folds and seals with transparent tape; The product flows into the strapping machine, the sensor senses a signal, and the equipment starts automatic strapping; The product flows into the weighing station, and the sensor senses a signal to automatically scan and weigh the product, and then upload the information to the MES system.

The MES system used throughout the entire line includes the MES basic platform (planning management module, production data collection, traceability management) and electronic signage. The system mainly includes servers, switches, electronic signage displays, SOP display terminals, barcode scanners, and upper computer software. The MES system reports station data for collection as needed. Require each workstation to automatically identify, record, release, and save data when passing through, and meet production needs.
