Frequently Asked Questions

1. What Is a Battery Test Chamber?

A battery test chamber is a testing device specifically designed to simulate various environmental conditions for testing various electrochemical energy storage devices such as lithium-ion batteries and nickel-metal hydride batteries.

2. What Temperature and Humidity Ranges Are Required for Battery Testing?

The required temperature and humidity ranges for battery testing depend on the specific standards and application scenarios. Most power batteries and energy storage batteries require a test chamber with a temperature range of -40℃ to +150℃ and an adjustable humidity range of 10% to 98%RH.

3. Do I Need an Explosion-Proof Battery Test Chamber?

Whether an explosion-proof battery test chamber is needed depends primarily on the test object and the test items. For lithium-ion batteries, power batteries, or energy storage batteries, and for tests that may cause thermal runaway, such as overcharge, over-discharge, and short circuits, an explosion-proof battery test chamber is generally recommended.

4. What Is a Walk-In Battery Test Chamber and When Do I Need One?

A walk-in battery test chamber is a device specifically designed for testing large batteries, suitable for power batteries, energy storage batteries, and large battery modules. When the battery size is too large or multiple battery samples need to be tested simultaneously, a walk-in solution is usually required.

5. What Safety Features Should a Battery Test Chamber Have?

A battery test chamber should be equipped with appropriate safety protection functions according to the battery's risk level. For lithium-ion batteries, power batteries, and energy storage batteries, common safety functions include over-temperature protection, smoke detection, emergency power cut-off, explosion-proof pressure relief, ventilation, and automatic fire suppression.
