Abstract: Transportation methods are changing, and electric vehicles (EVs) may replace to some extent combustion ones in the short-term. Nevertheless, new EVs technology does not transmit so much reliance due to its safety issues and limited range. Hence, in this paper, an introduction is made to outline EV's current state and safety problems, and it aims to give an overall view of the different available solutions to design a battery pack (BP) and their limitations. Due to the extension of the criteria to design a BP, this paper is focused on the cells (types, integration in the BP, and joining methods) and the thermal safety of the system [how to detect a thermal runaway (TR), battery thermal management systems (BTMSs) and cooling strategies] from the point of view of the implementation to the BP. Finally, some features that limit BP designs in which more research is needed have been identified.
