Electric vehicles signify the introduction of advanced technologies along with electric power components in vehicles. There are several risks associated with these technologies, such as thermal runaway of battery banks and fire, which need to be cautiously assessed. Numerous safety aspects need to be considered regarding vehicle electrification, including electric system safety, functional system safety, battery charging safety, and vehicle maintenance, operation, and training. The current challenges that hinder the popularity of electric vehicles are high battery cost, overheating, the total energy storage capacity of the battery, and the development of batteries for vehicles. Additionally, it is essential to examine the vehicle behaviour as these systems often fail, making them inefficient when compared to ICE vehicles. Thus, automobile manufacturers need to ensure that customers use systems that operate efficiently in varied conditions to effectively promote the use of these electrical systems and their components.

The electric two-wheeler set-up appears a lot more promising, in the form of research, financial acquisitions & investments, that makes the electric vehicle segment thrilling. Electric two-wheelers, by its swiftness and dexterity, easy operability and maintainability, affordability and low pollution, are most welcome among different categories of users. Mostly the customer segment that wants this change in pace includes city dwellers, short distance commuters, frequent road drivers and users of special needs. Besides personal use, electric two-wheelers also increasingly find their place in public service, such as urban sanitation, domestic and short distance patrolling, in delivery service, etc.
