Testing to ensure battery integrity
31 July 2020
Lithium-ion (Li-ion) batteries are a reliable and cost-effective power source, helping to revolutionise technology development.
Consumer and IoT (Internet of Things) electronic devices are becoming more compact with many power-hungry features – resulting in the battery pack also becoming smaller, but at the same time, requiring greater capacity.
Such devices are often carried in people’s pockets, increasing the potential safety hazard and risk of personal injury. Batteries must, therefore, be tested at all levels, with tests, including electrical, chemical, corrosive, mechanical, and abuse. These include:
• Life cycle testing – verifies how long a battery lasts and demonstrates the quality of the battery. These tests include life cycle testing, environmental cycle testing and calendar life testing.
• Abuse testing – simulates extreme environmental conditions and scenarios to test batteries beyond limits.
• Performance testing – demonstrates the efficiency of batteries, such as performance testing under various climatic conditions.
• Environmental and durability testing – shows the quality and reliability of a battery through testing vibration, shock, EMC, thermal cycling, corrosion, dust, salt and humidity.
