Battery Testing Solutions in Manufacturing and Production

Battery testing can be a broad term ranging from the characterization of tiny cells in portable devices to large vehicle batteries. The testing is done to track battery health, prevent unexpected failure, ensure adequate backup and predict cycle life.

Battery Testing Solutions

Battery technology is constantly improving to support even higher performance required for commercial and consumer applications, as well as mobility solutions like car electrification. With rapid progress in the production and development of batteries, the rapid growth of battery testing solutions is required to ensure enhanced safety, longer service life, and higher output. 

Types of Tests 

Generally, performance tests of battery cell/pack/module, management tests, and safety tests are conducted under battery testing.

A) Performance Tests:

• Cycle test ensures the battery performance in the line and end product. 
• Load test is performed to verify the specified power delivery of the battery.
• Additionally, performance monitoring is done using tests such as state of charge, state of health, impedance testing, and open circuit voltage testing.

B) Management Tests:

• Calorimetry test is done to ensure the battery management of the pack.
• Thermal imaging is done to detect hot spots.

C) Safety Tests: 

Some of the battery tests done to ensure the safety of batteries in manufacturing and production lines are as below:

• Mold stress.
• Insulation test.
• Leakage test for the casing.
• Short circuit test.
• Over-discharge or overcharge test to check tolerance  
• Mechanical test.
• Environment test.
