U-BTC

Battery test chamber

Designed for thermal battery testing.
Engeneered for safety in applications up to hazard level 4.

The Memmert U-BTC battery test chamber was specifically developed for thermal battery testing up to Hazard Level 4, combining precise temperature control with integrated safety features for reliable test conditions.

Designed for safe battery testing

Why it matters

Battery testing requires more than precise temperature control. Heat generated by the battery, the test procedure and potential failure scenarios all need to be considered when creating a reliable test environment.

Designed specifically for thermal battery testing up to Hazard Level 4, the U-BTC provides reliable conditions for testing at elevated temperatures.

Its temperature range from +20 to +120 °C covers a wide range of thermal battery testing requirements.

Its integrated safety concept combines pressure relief, mechanical door locking and process-dependent electronic locking.

For your battery testing

The U-BTC is designed for thermal battery testing from individual cells to complete battery systems. It supports a wide range of applications in development, validation and quality assurance, including test tasks related to standards such as IEC 62660, IEC 62619 and ISO 12405-4.

Typical users

  • Battery cell manufacturers
  • Automotive OEMs and suppliers
  • Energy storage providers
  • Test laboratories
  • Research institutions
Safety Features Come Standard

Key battery-specific safety features are built in from the start and require no separate configuration or ordering.

  • Pressure relief
  • Mechanical door locking
  • Process-dependent electronic locking
  • Door-open recognition
  • Interior nearly gastight
  • Signal lights for device status
  • Temperature restriction to +120 °C
Standards in Focus

The U-BTC supports typical thermal test tasks in the context of relevant battery standards. Which test procedures can be supported in a specific application depends on the battery under test, the required test conditions and the selected U-BTC model.

The Eucar Hazard Levels

Hazard Levels indicate how a battery may react during testing. The Memmert U-BTC is designed for applications up to Hazard Level 4 and must not be used for applications at Hazard Level 5 or higher.
