FIRE SAFETY OF LITIHIUM-ION BATTERIES IN ELECTRIC VEHICLES

The safety of lithium-ion batteries in vehicles is a priority of the automotive industry. The focus of the
development activities are the reduction of the risks and the improvement of the safety concepts and systems. A brief summary of the current state of lithium-ion battery technology at the cell and battery levels will be provided, with emphasis on safety features, dangers, statistical relevance, and recent occurrences or accidents. There will be a summary of hazardous incidents involving lithium-ion
batteries for automobiles this summary will only include information that is openly available. On the basis of this information, a statistical significance that takes into account both the present situation and the anticipated future will be displayed. As a result, there arent as many electric and hybrid vehicles available on the market, which reduces the overall number of safety-relevant events. Also
low is the risk in its entirety. Each electric or hybrid vehicle carries a substantially higher risk of
safety-related mishaps. In the end, it depends on the trigger employed. An excellent overview can be
obtained by employing a bottom-up safety assessment method that identifies the hazards and risks
associated with the usage of each cell, module, and battery in vehicles and describes the estimated
risks associated with each of these components. Additionally, a review of these other pertinent safety
measures will be provided. The fundamental conclusion of this research is that a lithium-ion batterys
safety level mostly depends on the cell chemistry and its capacity. Although the introduction of
chemicals may increase safety, it will also reduce capacity and performance and increase costs. Other
extra features wont affect battery safety in any way. This makes it possible to establish specifications
for the package, collision behaviour, and functional safety of cars. We will demonstrate and talk about
the principles and qualities that make up the present level of electric and hybrid car safety. Finally,
information regarding new developments in lithium battery technology will be provided, along with
details about pertinent safety features.
