Acquisition of an automated battery cell test station (Battery Test Bench)
Sketch of the battery test installation
Scope of investment project
Li-ion batteries are rechargeable energy storage systems, which can be found nowadays in different
applications, from portable electronics to automotive. Due to their high energy density, Li-ion systems are
gaining ground in applications such as electro-mobility or as buffers for power system networks.
Li-ion batteries have attractive characteristics with respect to other secondary batteries as the lack of memory
effect, a high open-circuit voltage and a low self-discharge. However, they also present some disadvantages
such as a high price, loss of capacity, increase of internal resistance and safety issues (overheating,
explosion, ignition). These limitations are the current challenges for the scientific and industrial communities.
Degradation, reliability and lifetime (power, capacity and durability) are of high relevance, and different for
each battery technology and application. The Empa Laboratory for Electronics/Metrology/Reliability is well
established to perform battery degradation and lifetime modelling and therefore is planning to buy an
automated battery cell test station. The planned equipment has a capacity up to 500V or 1000A
including safety boxes of hazard level-3. The acquisition of this new equipment will allow performing work
of specific CCEM projects and will be available to all laboratories in the ETH domain and other research institutes.
