“…Among these issues, thermal issues are considered to be the most critical. Thermal issues can significantly affect the operation as well as the life cycle of batteries [23,[49][50][51]. For example, high temperatures can cause combustion and explosion.…”

“…From a scientific perspective, thermal issues significantly influence the internal electro-chemical of batteries. In [44,50], authors showed the effect of overcharging and over-current on the viability of batteries. The over-charging and over-current also lead to thermal issues because of the increase in the Joule heat [43,44].…”

In recent decades, the trend of using zero-emission vehicles has been constantly evolving. This trend brings about not only the pressure to develop electric vehicles (EVs) or hybrid electric vehicles (HEVs) but also the demand for further developments in battery technologies and safe use of battery systems. Concerning the safe usage of battery systems, Battery Management Systems (BMS) play one of the most important roles. A BMS is used to monitor operating temperature and State of Charge (SoC), as well as protect the battery system against cell imbalance. The paper aims to present hardware and software designs of a BMS for unmanned EVs, which use Lithium multi-cell battery packs. For higher modularity, the designed BMS uses a distributed topology and contains a master module with more slave modules. Each slave module is in charge of monitoring and protecting a multi-cell battery pack. All information about the state of each battery pack is sent to the master module which saves and sends all data to the control station if required. Controlled Area Network (CAN) bus and Internet of Things technologies are designed for requirements from different applications for communications between slave modules and the master module, and between the master module and control station.

“…These protections are an inherent part of BMS systems [11,12] The purpose of BMS is to control the amount of energy reaching the cells during charging (from an external charger or recuperation), and the distribution of energy between battery modules. On the other hand, BMS limits the amount of power expended by batteries to the values allowed when charging.…”

“…The available instructions in the event of an electric vehicle fire were also analyzed [4]. Moreover, by analyzing the available information on the design of vehicle electrical systems, including BMS [11,12] they identified potential modernization of cells and power systems for electric vehicles increasing safety in the event of damage and reducing the chances of a fire. It should therefore be emphasized that in the analyzed literature, no method has been found to actively reduce the fire risk of batteries by lowering the state of charge.…”

For this work, the specific heat value of a Li-ion cell was determined experimentally as if it were a homogeneous body. The heat absorbed in the cell was compared with the amount of energy contained in the charged cell. It was found that a fully charged cell poses a risk of spontaneous combustion in the event of the release of electrical energy. On the basis of literature research, the combustion process of a lithium cell has been described. The formula was derived for the value of the state of charge that does not pose a risk of self-ignition. In view of the existing threats, the currently used protection against cell damage and tests to demonstrate the safety of cells were analyzed. It has been indicated that currently used battery management systems do not guarantee the safety in a state of developing thermal runaway process. A new active way of protecting cells in a battery has been proposed, consisting in sectoral discharge of cells. The use of this solution would be important for the improvement of fire safety in the automotive industry as well as in mining and in the construction of energy storage.

Probabilistic networks can be a useful tool for reliability modelling and risk analysis in the operation of technical facilities. In the article, the authors present the method of using probabilistic networks in the analysis of threats to the elements of the electric bus power supply system with a hydrogen fuel cell. Both the use of probabilistic networks as a tool supporting decision-making processes and the use of the latest achievements in the field of non-emission propulsion indicate a new area of research. The article presents the construction of a hydrogen bus with particular emphasis on the hydrogen storage and transmission installation. Next one specific case is considered where there is a leak in the hydrogen system with the simultaneous appearance of an ignition initiator in the form of a short circuit in the electrical system. Authors considered Fault Tree-Event Tree method in context of Bayesian networks technology. The conducted research has shown that there is a real risk of hydrogen explosion in a hydrogen fuel cell-powered bus and that it can be accurately calculated.
