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.

Hazard level	Description	Effect on the battery cell	Visual / acoustic alarm	Temperature limiter Tmax	Electrical door lock	Mechanical door securing	Reversible pressure relief flap	Fire detection CO₂ measurement	CO₂ / N₂ purging system	Continuous N₂ inerting / O₂ measurement	Overpressure relief / rupture disc
0	No effect	No effect. No impairment of functionality.	☒
1	Protection system activates	No defect. Cell recoverable; protection system repair required.	☒	☒
2	Defect, damage	Cell damaged. Repair required.	☒	☒	☒
3	Leak, mass loss < 50%	Electrolyte loss, no venting, no flame or fire.	☒	☒	☒	☒
4	Gas release, mass loss > 50%	Electrolyte loss, cell venting, no flame or fire.	☒	☒	☒	☒	☒
