A battery-driven revolution is currently transforming the world. From electric vehicles (EVs) and renewable energy storage systems to portable electronics and aerospace technology, the demand for powerful, reliable batteries has never been higher. Test requirements are increasing in parallel with the growth of complex and large battery systems. The current requirements extend beyond testing individual cells to ensure battery performance and safety. Analyzing battery modules and packs at various levels has become essential for studying real-world behaviors and potential risks. 

The Shift from Cell Testing to Module and Pack Testing 

Research and development of batteries has concentrated exclusively on individual cells. A significant transformation occurs in cells after they merge into modules and packs. The introduction of thermal management, issues of electrical balancing, and mechanical stresses leads to unknown operational challenges that cell-only testing cannot adequately address. 

Testing both modules and packs is the only method of ensuring accurate simulation and evaluation of battery performance under real-world conditions. 

Key Factors Assessed During Battery Module and Pack Testing 

Performance testing 

The energy delivery by battery modules and packs needs to be tested for performance to determine their energy output under different operational scenarios. The evaluation of battery capacity, efficiency measurements and power output data should be conducted at various temperature points and with varying current rates and cycling conditions. A complete performance assessment enables batteries to fulfill their intended operational demands, regardless of whether they serve in EV acceleration systems or long-duration grid storage applications. 

Aging and degradation testing 

This test assesses how battery modules and packs deteriorate over usage duration. The evaluation focuses on long-term charge-discharge cycling and various environmental conditions, which reveal development patterns that include capacity reduction, rising resistance, and multiple electrochemical deterioration mechanisms. Studying how materials degrade makes predicting equipment lifespan and determining maintenance requirements possible. 

Safety evaluation 

Safety evaluation is an essential step in mitigating the occurrence of thermal runaway, short circuits and mechanical failures. Experimental tests analyze modules and packs by subjecting them to conditions of overcharging, various thermal stimuli, vibration stress, and mechanical distress simulations. Tests reveal product weaknesses that can endanger battery safety before they are used by consumers or in any industry. 

Risks of Skipping or Underestimating Module/Pack Testing 

Failing to test battery modules adequately and packs can lead to costly and dangerous consequences. There have been real-world cases of: 

Without thorough module and pack testing, manufacturers risk damaging their reputation, facing legal liabilities, and putting users at risk.
