Product Description
ACEY-BCT503-512H lithium ion cell grading machine is designed for lithium battery formation, capacity grading, and comprehensive performance parameter testing. It adopts an advanced master–slave integrated testing system composed of an industrial computer and MCU-based control units. Featuring a robust structure, reliable performance, user-friendly operation, and high efficiency, this system delivers exceptional cost-effectiveness. It is an essential production and testing solution for lithium battery manufacturers, battery grading facilities, and research institutions.
Equipment Structure and Appearance
- One CPU board, providing unified control for the entire cabinet.
- Sixty-four 8-channel constant current boards, evenly distributed across four doors.
- Sixteen charging switching power supplies with four output groups each, with each power supply serving four constant current boards.
- Two keyboard panels for dual-sided operation (front and back).
- Thirty-two sets of quick-release clamps, each with 16 channels, equipped with 32 battery plastic trays. One type of battery tray is compatible with 18650, 26650, and 32650 batteries of different sizes.
Working Principle
- The equipment is controlled by a computer connection, which sends commands and collects data.
- The keyboard allows for manual operation of the equipment and displays parameters and status.
- The constant current board is controlled by the CPU and provides constant current and constant voltage functions.
