Project Backgroud
With the continued growth in market demand for lithium batteries in new energy vehicles, unmanned aerial vehicles (UAVs), and robotics, formation and capacity grading – as one of the core processes in lithium battery manufacturing – directly impact battery capacity, lifespan, and safety performance.
✅ High Energy‑Recovery Efficiency: Digital parallel regenerative power supplies.
✅ Highly Integrated Design：Hot‑press fixture formation all‑in‑one machines; water‑cooled capacity grading all‑in‑one machines.
✅ Comprehensive Fire Safety System：Integrated CO, smoke, and temperature three‑in‑one detection; water‑and‑gas combined fire suppression system.
✅ Data Communication and Traceability: Equipment supports data communication, local data storage, and automatic data upload. The entire line can be integrated into a unified system, enabling full traceability of product and equipment information throughout the entire process. The system can also interface with the factory MES system for digitalised data management, meeting the production requirements of the complete process chain.
Guanjia's lithium battery formation and capacity grading equipment, along with its battery back‑end production line solutions, have achieved the successful transfer of leading burn‑in testing technologies, inheriting the brand's superior product genes and reputation in key areas such as temperature uniformity, power feedback efficiency, and software system architecture.
First、Equipment Overview and Core Capabilities
1.Product Specifications：he entire line is compatible with cells featuring single‑side or double‑side tabs.
2.Pressure System：Controlled by a servo motor and gearbox, capable of maintaining pressure from 500 kg to 10,000 kg.
3.Rapid Model Changeover：One‑touch motor‑driven adjustment enables fast changeover between different cell thicknesses and single‑side/double‑side tab configurations.
4.System Architecture：Integrated all‑in‑one structural design, equipped with an automated overhead crane for loading/unloading. The equipment shelves support both high‑temperature operation and water‑cooling configurations.
Second、Specifications and Parameters
1.Dimensions and Layout：The equipment can be stacked in multiple layers to adapt to workshop ceiling heights.
2.Power Efficiency：Discharge efficiency ≥ 75%; charge efficiency ≥ 80%.
3.Power Precision：Current/voltage accuracy: ±(0.05% FS + 0.05% RD).
4.Temperature Uniformity：Temperature uniformity within each storage position can reach ±2°C.
5.Pressure Accuracy：≤ ±10 kg for pressures below 1,000 kgf; ≤ ±2% of reading for pressures above 1,000 kgf.
This equipment is applicable to enterprises engaged in high‑volume battery production, enabling battery charge/discharge characteristic testing, overcharge/over‑discharge tolerance testing, cycle life testing, capacity testing, and dynamic response testing.
