Battery cell evaluation & stress testing

ESPEC environmental chambers ideal for battery cell evaluation 

Battery technology is now a critical component in how we use and generate electricity.  Evaluation tests of solar batteries exposed to demanding environments and all devices for power generation, storage and control is one requirement for the wide spread adoption of these new chemistries.

The rise of eco-friendly vehicles such as hybrids and electric vehicles is also seeing growing demand for environmental tests and safety tests of devices such as secondary batteries to ensure the high safety and stable performance required.

Premium features for the ultimate in testing flexibility and safety:

  • Manufactured to UL, IEC, SAE and EUCAR 1- 6 standards
  • Accommodate small battery cells & modules to large battery packs & battery cells
  • Risk-free testing to investigate safety, performance & reliability
  • Ideal for testing NIMH, lead acid & lithium ion batteries
  • Built-in safety features reduce the chance of explosions


Platinous Series environmental test chambersPlatinous Series

The Platinous series delivers a variety of sizes, ranges, and options to meet your specific battery testing requirements. The ESPEC Platinous series includes many standard features enabling a safe environment for efficient and effective battery testing.

Class leading volumes from 120 litres to 800 litres



AR-series-environmental stress chambersAR Series

The AR chambers have an increased tolerance to support heat loads from specimens and provide superior levels of temperature change performance and wide temperature & humidity control range. The line-up consists of twenty chambers that can be selected in accordance with temperature & humidity range, internal capacity and temperature change rate. Temperature change rate is between 4K/minute and 18K/minute, which conforms to IEC standards and test standards for automotive parts.


Unitemp & Espec are playing a critical role in supporting battery research at the University of Warwick.  The Energy Innovation Centre at WMG on Warwick University’s campus is aiming to establish new battery chemistries and manufacturing techniques working with many global automotive partners. In the video Mark Amor-Segan, principal research engineer, and Dr. Yue Guo, Deputy Head of the Energy Innovation Centre, explains how the unique facilities enable them to move from experimental chemistries right through to cell manufacture and battery deployment.
