Testing that Reaches the World

Clark Testing performs isolation testing on batteries to assess their electrical isolation and ensure they are free from unwanted electrical connections that could lead to short circuits or other hazards. This testing is particularly important for batteries used in high-voltage applications, such as electric vehicles, renewable energy systems, and industrial equipment.

Isolation testing verifies that the battery's electrical components are properly isolated from each other and from the battery casing, reducing the risk of electrical shock or fire.  The test will also identify any unintended paths for current flow that could compromise the battery's safety and performance.

When conducting the isolation test, the Clark Test team will ensure the battery is fully charged and brought to a stable state before testing to ensure accurate results.

We then apply a high voltage between the battery terminals and its casing or between individual cells to measure any leakage current that flows.

During the test, the following parameters are observed:

1. • Leakage current levels
   • Voltage applied
   • Physical changes in the battery, if any

The isolation test enables our customers to understand the effectiveness of the battery’s electrical isolation and identifying any potential safety risks.  This test also detects any leakage paths that could compromise battery safety and performance.
