SEMCO HYNN OCV tester can automatically test for the open circuit voltage, AC internal resistance, and shell cover insulation (the voltage between the positive electrode and shell) of the single cell in the battery tray. OCV testing is the essential process of battery manufacturing. Combining battery testing with battery tray for batch testing or single testing, it can reach fast and reliable testing results. The production management and control system automatically calculates the K value according to the test data, and automatically completes the binding of the production data information, automatic saving, and binding information. Data can be exported through the internet connection.

  • Test of the battery open circuit voltage (OCV)

  • Test of the battery AC internal resistance (ACR)

  • Battery shell and cover insulation test (voltage between positive electrode and shell)
