Abstract
The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric
Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of
an ongoing fire and what preventing measures can be made by Kalmar Globals customers to
create a safe environment and reduce the probability of a fire breaking out. This thesis builds on
information gathered during a literature study and a complementary interview study.
Fires in lithium-ion batteries generate a high heat release rate and a smoke production
consisting of a mix of toxic and flammable gases. This thesis finds that the bigger the battery the
larger the scale of the consequences will be. Compared to a conventional electric... (More)

Fires in lithium-ion batteries generate a high heat release rate and a smoke production
consisting of a mix of toxic and flammable gases. This thesis finds that the bigger the battery the
larger the scale of the consequences will be. Compared to a conventional electric vehicle such as
a car, Kalmar Globals working machines are larger in size and mass due to the ability of lifting
heavy objects. Despite a larger size the heat release rate of Kalmar Globals machines is not
proportionally higher than that of an electric car. Compared to a diesel driven version of the
same model of forklift or reachstacker, the heat release rate of the electric version is marginally
higher with the smallest battery size available for the Heavy Electric Forklift producing the
equivalent heat release rate.
When it comes to actions that can be taken during a fire in a lithium-ion battery an important
aspect is that of making sure there is good ventilation to reduce the concentration of toxic gases
as well as limit the spread to nearby objects. Measures that can be taken as a preventing action
include creating a safe place for the charging of the battery. (Less)
