l It is designed for use in the formation and grading of lithium ion rechargeable cells.
l Each channel owns constant current-constant voltage circuit, smooth transition from constant current to constant voltage, so channels will not influence to each other.
l Modular design ensures reliability and easy maintenance.
l Automatic adjust charge current, discharge current and constant voltage for easy operation.
l Each cabinet has 16 groups, as it is bilateral structure, with 8 groups on each side and 32 test channels each group, so the whole cabinet with 512 test channels.
l Five grading modes: capacity grading, time grading, capacity plus curve grading, time plus curve grading, capacity plus voltage grading.
l It provides two kinds of software to test data (you can only choose one): 1. Testing process allows 16 steps parameters and store 16 curves of cell charge and discharge. 2. Testing process allows 64 steps parameters, 256 circles. Every channel saves the whole data and curves of experiments process.
l Every channel has a LED indicator which shows the test state of cell.
l Communication: RS-485, baud rate: 57.6Kbit
l Every computer can control 1~10 set(s) of equipment at the same time.
l It can protect data when power failure and continue to run when power is restored.
l The equipment can work off-line.
