Cylindrical Battery Formation and Grading Machine for 18650 21700 26650 32650


1. Equipment Function Introduction

This testing systemis used for pre-charging activation of lithium battery and capacity sorting of finished battery. It is mainly composed of computer system and control software, communication interface and battery testing cabinet.

Operation procedure: the battery clamps symmetrically placed onequipment, before loading, adjust the width of the clamps, manually insert the battery cells into the clamps. The formation or capacitygrading processsent by computer or control panel, then start the equipment, then testing is completed, the data can be sent to EXCEL, ACCESS, WORD files, and exported to the database system.
