Fire safety exercise
In November and December 2019, the company AccuPower conducted fire tests with lithium-ion cells in cooperation with the Fire Protection Forum Austria. In particular, the fire behaviour of the batteries due to external temperature and flame effects was investigated in the specifically for the storage of lithium-ions designed Lithium Safe.
As preventive fire protection is becoming increasingly important in the storage and transport of lithium batteries, AccuPower tested the special Lithium Safe as part of in-depth fire protection exercises in order to gain knowledge for the further development of the Lithium Safe.
On 02 December, another lithium fire safety test was successfully carried out in a prototype of the safe under the supervision of renowned experts from the Fire and Civil School in Lebring .
For this purpose, various battery packs with a total capacity of 7250 Wh were set on fire simultaneously inside it.
The knowledge gained will now be incorporated into the further development of the lithium safe to ensure the highest possible safety standard.
The test showed that the lithium-ion cells can burst at temperatures as low as 250°C, releasing a large amount of decomposition gases. At temperatures of 600°C and above, the cells burn in a chain.
The Lithium Safe, which was specially designed for the storage of lithium cells, has a pipe feed with nozzles through which cooling water can be introduced. By flooding the burning battery cells, the fire was quickly brought under control.
