“…According to the authors of paper [129], it is important to check whether the battery in a burning EV/HEV is on fire or not. Self-intensifying exothermic processes in the battery can lead to the release of toxic substances in the form of hydrocarbons (HCs), carbon monoxide (CO), and especially hydrogen fluoride (HF).…”

The electrification of road transport is developing dynamically around the world. Many automotive companies are introducing electric vehicles to the market, and their popularity is constantly growing. The increasing popularity of electric vehicles is caused by individual countries’ governments encouraging people to switch to electric vehicles and their lower operating costs. In 2022, the number of electric vehicles in China will exceed 10 million. Europe and the USA rank second and third in global electric car stock, respectively. The number of available electric vehicle models is constantly growing, remaining approximately 2.5 times smaller than the case of vehicles with an internal combustion engine. Among others, a significant limitation to the popularity of electric cars is users’ fear of range and the density of the charging infrastructure network. This paper presents the objectives regarding public areas and charging stations around the European Union’s comprehensive and core transport network. It is worth noting that the vehicle and charging point’s charging connectors vary depending on the geographical region. Therefore, the currently used charging connectors for different regions are presented. Charging time depends significantly on the charging current, the power of the charging point, and the devices installed in the vehicle. The paper analyzes the limitations of charging power resulting from the onboard charger’s power and the charging point’s power. It presents the charging time of selected electric vehicles. The second aspect that is also the subject of user concerns and discussed in this article is issues related to the safety of electric vehicles. General safety indicators of such vehicles based on Euro-NCAP tests are characterized. Attention was also paid to more detailed problems related to active and passive safety and functional safety analyses. The issue of the fire hazard of electric vehicles was discussed together with modern experiences regarding post-accident procedures in the event of fires.

“…These potential dangers could result in a wide variety of incidents, including fires and explosions, as well as mishaps on the road and many more. Because of the inherent dangers of electric vehicles, it is crucial to take a cursory look at each of these aspects to ensure that EVs can function effectively while incorporating any necessary upgrades [148].…”

“…If one of the battery's cells experiences thermal runaway, the high temperature produced by that cell will cause damage to any adjacent cells that it is in contact with. Because it involves an exothermic reaction during the decomposition process, this process, which is brought on because of the thermal runaway in an EV, is difficult to stop [148].…”

“…Accidents can happen when adjusting the level of an electric vehicle (EV) because of the potential for harmful situations, such as when the jack becomes lost and accidentally pushes the high-voltage battery. Because an EV contains so many different electrical components, there is a small but real risk of starting a fire when placed onto a tow truck [148].…”

Electric transportation will assist in lowering emissions of greenhouse gases and mitigating the impact of rising petrol prices. To promote the widespread adoption of electric transportation, a diverse range of charging stations must be established in an atmosphere that is friendly to users. Wireless electric vehicle charging systems are a viable alternative technology that can charge electric vehicles (EVs) without any plug-in issues. Wireless power transfer (WPT), which involves the transmission of electricity via an electromagnetic field despite the presence of an intervening area, holds out the possibility of new prospects for EVs to increase environmentally responsible mobility. This review article examines the WPT technology and how it might be applied to electric vehicles from both a technical and safety standpoint. The prime aim of this review is (1) to illustrate the current state of the art in terms of technological advances as well as research limitations in the field of WPT development and use within the field of transportation; (2) to organise the experimental the deployment of WPT EV systems in the actual world; and (3) to analyse the results over a sustainable period and to identify limitations as well as chances for growth. From a technical point of view, the progress that has been made on the selection of material for designing coils, different types of coils with a specific focus on the overall performance of the system. As a result, this study aims to provide an extensive overview focusing on the magnetic materials and the architectures of the transmitter and receiver pads.

“…However, the safety of spent batteries is often less emphasized compared to the safety of electric vehicle (EV) batteries (Fig. 1A) [3][4][5]. As safety hazards could be generated with only small amount of external force, safety of spent batteries is important.…”

To achieve recycling without safety hazards by explosion of spent batteries, an efficient full discharging procedure is required to stabilize the batteries before recycling. However, typical salt solution discharging technique has environmental pollution, inefficiency, and safety issues due to wastewater emission, slow discharging rate, and severe voltage rebound. Electrical discharging techniques can be applied to overcome these problems, but the typical constant-current and constant-current constant-voltage modes have a tradeoff relationship between discharge time and voltage rebound. In this study, we propose reverse voltage mode as an expeditious and safe electrical discharging protocol that effectively addresses the trade-off between discharging time and voltage rebound. The proposed reverse voltage mode for full discharging method was proven to be effective regardless of the electrode crystal structure or the battery form factor. This result is expected to present new methodology for pre-stabilization of spent batteries for more ecofriendly and stable recycling.
