Lithium-Ion Battery Aspects on Fires in Electrified Vehicles on the Basis of Experimental Abuse Tests
Artikel i vetenskaplig tidskrift, 2016
Safety issues concerning the use of large lithium-ion (Li-ion) batteries in electrified vehicles
are discussed based on the abuse test results of Li-ion cells together with safety devices for cells.
The presented abuse tests are: overcharge, short circuit, propane fire test and external heating test
(oven). It was found that in a fire, cells with higher state of charge (SOC) gave a higher heat release
rate (HRR), while the total heat release (THR) had a lower correlation with SOC. One fire test resulted
in a hazardous projectile from a cylindrical cell. In the fire tests, toxic gas emissions of hydrogen
fluoride (HF) were measured for 100%, 50% and 0% SOC.
