19311 Series

The Chroma 19311 series Battery Cell Surge Tester, is designed for testing the insulation quality between the positive and negative plates of the lead-acid battery cell. This is done by applying a high voltage surge/ impulse before the electrolyte injection. Its output voltage can reach up to 6kV. It also has four terminal measurement and 200MHz sampling rate. The Chroma 19311 series has single channel (19311) and multi-channel (19311-10) tester.

The 19311's surge test applies a non-destructive low energy impulse voltage to the lead-acid battery cell. During the surge test, the lead-acid battery cell resonates with the internal inductor in the 19311. The tester then determines if the insulation is defective or not by analyzing the resonant waveform or comparing the test waveform with a golden sample waveform. Testing the lead-acid battery cell with a high voltage surge before the electrolyte injection checks the insulation distance and the insulation quality between the positive and negative plates, determines the integrity of the separator between the positive and negative plates, and identifies if the positive and negative plates are shorted.

Chroma's 19311 series analyzes the differences of the insulation quality from the resonant waveform using 8 types of judgements for analysis: Area, Diff-Area, Flutter, Laplacian, V1, V3, Peak Ratio and Delta Peak percentage.

19311-10 Tester

The 19311-10 has 10 channels, which can test up to 9 battery cells via scanning test, with a single unit. It can support up to 25 channels for testing up to 24 cells in a sequence by connecting with an external scanner (A190362). The test speed of the multicell scanning test by 19311-10 is extremely efficient, saving test time, and decreasing labor costs. It also increases the production capacity of the production line.
