The model of positive and negative electrode insulation fault is established by equivalent the electrode insulation fault of the battery pack.
How to test battery cell insulation resistance?
Battery cell insulation resistance testing is generally carried out as follows (*1): DC voltage is applied between each cell’s anode and cathode, and the insulation resistance is measured. DC voltage is applied between each cell’s electrodes and enclosure, and the insulation resistance is measured.
What is the insulation resistance of a battery pack?
The voltage of the battery pack remains constant, and the insulation resistance jumps periodically to simulate a sudden insulation fault. The insulation resistance test results are plotted in Fig. 6. In this case, the positive side insulation resistance gradually increases from 210KΩ to 280KΩ, and the increased amplitude is 10KΩ.
How does a battery insulation tester work?
Insulation testers use either the resistance method or the constant-current method to provide discharge functionality. When testing battery cells, the constant-current method offers faster discharging, which translates into shorter test times.
What voltage is used in battery insulation resistance testing?
The test voltage is the voltage that the insulation tester applies to the cell under test. The appropriate test voltage varies from battery to battery. DC voltage of 100 V to 200 V is generally applied in battery cell insulation resistance testing. Recently, it has become more common to use a low voltage such as 5 V or 50 V.
Can a balanced bridge detect a battery insulation fault?
