ESPEC environmental chambers ideal for battery cell evaluation

Battery technology is now a critical component in how we use and generate electricity.

The rise of eco-friendly vehicles such as hybrids and electric vehicles is seeing growing demand for testing of battery cells and packs under precisely controlled testing environments.

Evaluation tests of new chemistries for solar batteries exposed to demanding environments and other devices used for power generation, storage and control also need a safe environment to undertake rapid temperature and humidity cycling during charge/discharge and safety testing.

ESPEC produce a range of Test chambers that are ideally suited to meet the most demanding needs of battery testing and are manufactured to meet UL, IEC, SAE and EUCAR 1- 6 standards

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

The Platinous series test chambers come in a variety of sizes, ranges, and options to meet your specific battery testing requirements both for temperature and humidity cycling. The ESPEC Platinous series includes many standard features enabling a safe environment for efficient and effective battery testing, and safety options are available to bring the Chambers up to the EUCAR 6 standard.

Class leading volumes from 120 litres to 800 litres

AR Series

The AR fast rate environmental test chamber chambers have an increased tolerance to support heat loads from specimens and provide superior levels of temperature change performance and a wide 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. 

SH/SU Series

In charge-discharge tests, speciments are repeatedly charged and discharged while undergoing prolonged exposure to a uniform temperature envronment.
SH/SU chambers are capable of maintaining a stable temperature and environment for long periods of time.

SPH Series – High-Temperature Chamber with Pressure Relief Vent

The SPH series sets the industry standard for high-temperature chambers for product testing, including applications like battery testing that carry the risk of explosions. These chambers come equipped with essential safety features in the form of pressure relief vents, which serve to mitigate explosion pressure. In the event of an explosion, the pressure relief vent, efficiently releases pressure from the top of the chamber.

These temperature chambers provide exceptional ease of use and temperature uniformity. Additional safety features, including an automated fire extinguishing mechanism, can be added upon request.
