JH5V400A-16CH Square Cell Capacity Grading and Testing Cabinet
This equipment is primarily used in the charge–discharge formation and capacity‑grading processes for square‑shaped batteries. It simultaneously acquires voltage, current, and other parameters during charging, locally stores this data, and uploads it for further processing, enabling traceability of cell‑capacity‑grading information. The device features low heat generation, energy efficiency, modularity, and compactness. It comprises key modules such as a power‑supply cabinet, a pressing‑station module, and backend monitoring software.
