Rechargeable lithium batteries have been the choice for portable electronic devices. As they now become important for electric vehicles, reliability and safety become paramount. The batteries must perform well in hot and cold conditions, while not posing a hazard due to leaking or exploding.
Through temperature testing with ESPEC chambers, the batteries’ ability to withstand environmental extremes and stress can be identified safely.
For more information on Battery test standards, see Battery Test Methods and Specifications.
Because battery failure is a real risk (and sometimes its a desired outcome), environmental chambers need safety systems to protect from harmful explosions and ensure operator safety.
Of greatest risk is the release of gases from a battery, which may ignite on their own, or by the test chamber’s heaters. Special low-temperature heaters are recommended, but additional precautions may be necessary. By monitoring the battery for thermal runaway, the chamber may be shut off and an alarm made prior to an explosion.
Based on your testing needs and safety requirements, ESPEC can help with the following options to create a complete testing system.
