Product description:

The battery cycler is used for lithium-ion battery pre-charge activation and capacity sorting of finished battery cells. It is mainly composed of computer system, control software, communication interface and battery testing cabinet, which is composed of a panel with fixture, charging constant current and voltage source, discharging constant current source, host control circuit, current sampling circuit, voltage sampling circuit, main control CPU, data storage system, microcontroller program and control panel, and ventilation system.

Brief operation procedure: The battery life cycle testing equipment is arranged symmetrically for the battery fixture, adjust the width between the fixture before loading, put the battery into the fixture by hand, send the formation or capacity sorting command through the computer or panel, start the formation and capacity sorting equipment, formation or capacity sorting according to the set conditions, after that the data can be sent to EXCEL, ACCESS, WORD file and exported to the database system.

Scope of application:

The battery cycler is primarily used for battery cell cycle life testing, but can also be used for battery cell pre-charge activation and capacity grading sorting. It is suitable for various types of cylindrical lithium battery cells, such as 18650, 21700, 26650, etc. For the battery pack assembly factory, the capacity of the battery cells can be further tested and sorted to ensure the quality of the battery pack.

The Battery Cycler Characteristic:

1. Energy efficient power supply systems.

2. Energy recovery circuit design.

3. Modular design for easy maintenance.

4. Auto-clip design simplifies operation.

5. Low miscarriage of justice for patented thimble designs.

6. Compact and space efficient.

7. Supports offline mode of operation.
