Product overview:
The prismatic cell battery grading machine grades the prismatic cell capacity by performing several charge-discharge cycle tests on prismatic cells to obtain accurate battery capacity.
For battery cell manufacturers, the battery grading machine is one of the necessary machines in the cell manufacturing process.
For battery pack assemblers, battery capacity testing and grading must be carried out before assembling the battery pack, cells with high capacity consistency are grouped, and then the prismatic cell sorting machine is used for OCV/IR testing and sorting, thereby improving the consistency of the cells in the same battery pack, so as to assemble the battery pack with the best performance.
1. Basic composition of equipment
The equipment is mainly composed of computer, communication interface and battery detection cabinet. The battery detection cabinet is composed of a fixture and a board for placing the fixture, a constant current and constant voltage source, a storage control circuit, a sampling circuit, a single-chip microcomputer and a control panel.
