Project Background
With the rapid development of new energy vehicles and energy storage systems, the market demand for large‑capacity prismatic batteries continues to grow steadily. 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：Series‑type regenerative power supplies for formation; PCS‑based parallel regenerative power supplies for capacity grading.
✅ Highly Integrated Design：High‑temperature series‑type 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：The entire line is compatible with 618Ah, 588Ah, and 314Ah cells.
2.Negative Pressure System：Each storage position is equipped with an independent negative pressure system, featuring proportional valve‑type stepless negative pressure regulation.
3.Rapid Model Changeover：A diversified probe structure accommodates various cell terminal configurations and enables fast changeover between different battery chemistries and form factors.
4.System Architecture：Integrated all‑in‑one structural design, incorporating PCS‑based high‑voltage DC bus and digital regenerative power supply technology. The equipment supports both high‑temperature operation and water‑cooling configurations.
Second、Specifications and Parameters
1.Dimensions and Layout：Temperature uniformity within each storage position can reach ±2°C.
2.Power Efficiency：Current/voltage accuracy: ±(0.05% FS + 0.05% RD).
3.Power Precision：Discharge efficiency ≥ 75%; charge efficiency ≥ 80%.
4.Temperature Uniformity：The equipment can be stacked in multiple layers to adapt to workshop ceiling heights.
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.
