Maccor 5300 Formation System

Maccor S5300

Automatic Cell Formation & Grading System

The Model 5300 Grading System is a quality control tool that provides an efficient and economic method of grading cells by Capacity. The need to grade cells has become increasingly important in the manufacture of battery packs. In particular, battery packs that are used in the more demanding applications that typically incorporate Lithium or NI-MH cell technology.

The basic system can accommodate up to 256 cells. Multiple systems can be supplied, operating from a single PC computer. The Model 5300 is supplied in a cabinet intended for bench top mounting, which contains cell contact plates, power supplies, and measuring and control electronics.
In operation, cells are placed into cell trays, and the trays inserted into the test cabinet. Cell trays are available for a range of different diameter cells. Under the control of a single board computer in the test cabinet, cells are subjected to a pre-programmed sequence of charge, discharge, and rest steps. As the test proceeds, measurements are made of current and voltage at a rate of approximately one data point per second for each and every cell. At the end of the test, a print out is obtained indicating the grade classification of each cell, based on operator programmed criteria.

Both the programming of the test, and the calculations necessary to provide grading information, are performed through the system PC computer. The Maccor Windows based software allows the operator to enter one or any number of test programs through a fill-in-the-blanks menu screen.

At the appropriate charge, discharge or rest step, the operator also enters the information required for grading purposes, typically a band of capacity measurements. From the PC computer, the operator can start and stop tests, monitor system status, and view real time test data on each cell.
The design of the Model 5300 is based on the same concepts and principles of our other proven laboratory and production battery test systems. It therefore provides a system with high accuracy, flexibility, ease of operation, and reliability.
