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


BTC Series

The Espec BTC Series are dedicated chambers for safe battery charge-discharge testing. BTC chambers are equipped with safety devices proven in battery explosion tests to provide optimal protection against hazards. Designed with safety as a top priority, the BTC is equipped with a large, reusable pressure relief vent that safely relieves pressure in the event of a battery explosion. Other safety devices can also be selected and added as needed. This safe and environmentally friendly tester will strongly support your testing.

The BTC chamber allows the user to select the direction of the air flow, thus suppressing the wind blockage caused by the cell shape and realizing a test with minimal temperature difference.

Platinous 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

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.
