Temperature and humidity chambers designed for testing batteries

There are three standard test procedures that can be undertaken:

1. Checking the performance of the battery when it is charged and discharged repeatedly in a specific environment.
2. The temperature characteristic test that checks the characteristics when the secondary battery is charged and discharged at various temperatures within the range -30 to +30degC.
3. The storage test that checks the stability and any gas leakage when storing the batteries between a temperature range of -10 and 70degC.

ESPEC's Platinous range of environmental test chambers, now available through Unitemp, comprises four models with a temperature range of -40 to +150degC, while two of the models also have a humidity range of 20 to 98 per cent.

Safety features

Because the testing of batteries can produce unpredictable results, safety features are included to help protect operators. These include a gas detection system with a wide temperature range, a rapid air exchange function, a pressure relief vent, a reinforced chamber door, a safety door lock, a control signal for external systems, a fire extinguisher system and an additional overheat protector.

The Platinous chambers are constructed inside and out from stainless steel and have internal measurements of between 500 x 600 x 750mm and 1000 x 900 x 1000mm.

An optional viewing window has pane heaters to help keep them clear of condensation and frost, and a chamber light is built into the window for viewing the battery under test. Other features include an easy-to-use control panel, hinged service panels for easy access, and castors.

These new test chambers complement Unitemp's already extensive range of test and monitoring chambers and ovens. Furthermore, Unitemp has the expertise to customise chambers if required.
