Battery Testing System (BTS)
NEWARE CE-6001n-100V400A


This system is used for cell modules. This means that a defined cycling program is written via the according BTS-software and via those configurations the test cell is treated under certain conditions. For example a specific charge- and discharge-program is used to generate a certain state of charge (SOC) for experiments.

Gas analysis



Two different methods are used in parallel to quantify the gas composition:


• The gas-chromatograph (GC) quantifies H2, N2, O2, CO2, CO, CH4, C2H4, C2H6 and C3H6


• The Fourier Transform Infrared Spectroscopy (FTIR) detects all ventgas-components except H2.


For each measurement the results of these two complementary methods are combined into one report.

Laboratory
Fume Hood


This area contains an area for preparing the test cells and to cover general chemical and technical work, measurements and the Foil-testbed. We can tear down discharged cells.


The Foil-testbed is a test bed created at ViF which was originally used for measuring the effective thermal conductivity of spacer materials, nowadays it is used in a wide variety of tests e.g. compression tests of cells, measuring the electric resistivity of Thermal Runaway dust and more. The updated test bed can measure forces up to 10 kN, reach temperatures up to 900 °C and measure distances with an accuracy of ~0.01 mm over 15 cm range. It can also be modified for measuring currents and voltages used for measuring the electrical conductivity at different pressures and temperatures.

RD350B
Reactor (diameter: 30,5 cm)


First we prepare a sample holder with the tested cell and the thermocouples. The sample holder is placed in this pressure vessel. Then the thermocouples, cell-terminals, voltage sensing and the electric heaters are connected to the connector block. On the other side the connector block is wired to the measurement system, to the cell-cycler and to the power supplies. After connecting the sample holder we close the reactor making it pressure tight. If necessary we can flush the reactor with a defined atmosphere (N2 or air) at and set the gas pressure to a defined value.


Then we start the experiment and track the connected sensor values and the gas pressure in the reactor. After the experiment we analyze the gas composition, flush the reactor and remove the sample holder.


Typical experiments


• Heat ramp
• Hot spot (heating cardridge attached to the cell)
• Overcharge
• Nail-penetration
• Eletrical cycling beyond cell specification

RD600A
Reactor (diameter: 60,0 cm)



This pressure vessel generally is used for tests which are to dangerous for climate-chambers but where we do not expect cell venting and thermal runaway to happen. It can be used to cycle prototype cells and for aging of prototype modules.


RD600A has the same dimensions as RD600B.

RD600B
Reactor (diameter: 60,0 cm)



This pressure vessel is larger than the RD350B. Same experiments as in the smaller RD350 can be done here, but it is also suitable for larger experiment setups which need more space, for example for cell stacks. This reactor allows to use liquid cooling (e.g. water-glycol based or dielectric coolant) during TR and TR-propagation tests.

for manual work


Here we prepare the safety experiments and assemble the sample holders. We can also build prototype modules or cell- stacks.


When it comes to experiment preparations those benches provide enough space. A feature is the tool wall and the defined order of tools on it. This simplifies work processes and saves time.
