BINDER climate chambers verify the safety of energy storage devices

March 2020 BINDER and safety

New safety standard for battery tests


The growing popularity of electromobility solutions is being accompanied by increased demand for wireless electrical appliances – leading to consumers requiring an ever-larger supply of lithium-ion batteries. But the demands being placed on the batteries themselves are also changing, as consumers look for improved performance and guaranteed safety. These aspects are assessed on the basis of defined standards and generally evidenced through a seal attached to the product.


Munich-based service provider TÜV SÜD uses a number of BINDER chambers – specifically, dynamic climate chambers and cooling incubators – to test numerous energy storage devices from a range of manufacturers. One attribute that it tests is whether batteries are able to withstand thermal changes. Whether they are faced with hot, cold, or humid conditions, batteries have to keep performing as they are expected to, which means no malfunctions or worst-case scenarios: an explosion in the unit with potentially fatal consequences. TÜV SÜD also subjects the batteries to mechanical testing, exposing them to shock, vibrations, and reduced pressure.


The IEC 62133:2012 standard was replaced with IEC 62133 on March 14, with the new version now governing all energy storage devices produced from this date onward. It represents the latest and most important battery safety standard that is currently in practice.


Batteries produced before this date can continue to be used without restrictions.


The University of Warwick in the UK is one example of a location that is using BINDER chambers for battery testing. Another is MEET, the battery research center at the University of Münster in Germany.
