The future of energy storage

Energiespeicher der Zukunft

 

Batteries are an integral part of mobile systems like smartphones and laptops – but they can also be found storing large quantities of energy in stationary storage systems. These days, electromobility is one of the most significant fields in which they are used, with lithium-ion batteries being integrated into hybrid and electric vehicles with increasing frequency.

Batteries are truly the future of energy storage – and to ensure they are able to perform safely and reliably, they need to be put through their paces in tests. To conduct tests on lithium-ion batteries, BINDER offers temperature and climate chambers equipped with a range of safety packages that are aligned with EUCAR Hazard Standards, environmental requirements, or test types.

Battery test chambers are used in research and development, quality assurance, and battery production alike. The packages can be adapted to a variety of BINDER models in order to meet test requirements relating to temperature range, climate range, and test area size.

What tests can be performed with BINDER safety packages?

Anwendungen Battery Testing

Aging tests:
These involve testing at a certain temperature without the battery load cycle. They are performed within a safe temperature range for the battery.
BINDER solution: Package A

Performance test:
Various battery-specific parameters, such as the load state, are tested with overlapping temperature ranges. These tests are performed within a safe temperature range for the battery.
BINDER solution: Package P

Stress tests:
Various battery-specific parameters, such as the load state, are tested with overlapping temperature ranges. These tests are performed at the limit of the safe temperature range for the battery. This category also includes tests with higher charging and discharging currents overlapping with constant or dynamic temperatures.
BINDER solution: Package S

What classifications apply to handling energy storage devices?

The EUCAR Hazard Standards are used to assess the level of danger associated with handling batteries. They have been defined by EUCAR (the European Council for Automotive R&D) by classifying the hazards presented to batteries and describing the consequences of them. BINDER offers three packages with additional safety measures based on these effects on batteries.

No effect, no loss of functionality

No defect; no leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway.
Cell reversibly damaged. Repair of protection device needed.

Same as hazard classification 1; however, the cell is damaged irreversibly and must be replaced.

No venting, fire, or flame; no rupture; no explosion. Weight loss < 50% of electrolyte weight (electrolyte = solvent + conducting salt)

No venting, fire, or flame; no rupture; no explosion. Weight loss > 50% of electrolyte weight (electrolyte = solvent + conducting salt)

No rupture; no explosion (e.g., no flying parts)

No explosion, but flying parts of the active mass.

Explosion (e.g., disintegration of the cell)
