Maintenance, Safety & Battery life in Electric vehicle (In short)

Safety -

EVs must undergo the same rigorous safety testing and meet the same safety standards required for conventional vehicles sold in the United States as well as EV-specific standards for limiting chemical spillage from batteries, securing batteries during a crash, and isolating the chassis from the high-voltage system to prevent electric shock. In addition, EVs tend to have a lower center of gravity than conventional vehicles, making them less likely to roll over and often improving ride quality.

One safety concern specific to EVs is their silent operation; pedestrians may be less likely to hear an EV than a conventional vehicle. The National Highway Traffic Safety Administration is studying ways to address this issue, such as requiring EVs to emit audible sounds at low speeds. This option is already available on many EVs, including the Chevrolet Volt and Nissan Leaf. In any case, you should use extra caution when driving your EV in pedestrian areas.

Maintenance -

Because of their differing technologies, all-electric vehicles (AEVs) and plug-in hybrid electric vehicles (PHEVs) have different types of required maintenance. Both will require minimal scheduled maintenance to their electrical systems, which can include the battery, electrical motor, and associated electronics. However, because of regenerative braking, brake systems on EVs typically last longer than on conventional vehicles.

In general, AEVs require less maintenance than conventional vehicles because there are usually fewer fluids (like oil and transmission fluid) to change and far fewer moving parts. In contrast, because PHEVs have gasoline engines, maintenance requirements for this system are similar to those in conventional vehicles.

Battery Life -

Like the engines in conventional vehicles, the advanced batteries in EVs are designed for extended life, but will wear out eventually. Currently, most manufacturers are offering 8-year/100,000-mile warranties for their batteries. Nissan is providing additional battery capacity loss coverage for 5 years or 60,000 miles. Manufacturers have also extended their coverage in states that have adopted the California emissions warranty coverage periods, which require at least 10-year coverage for batteries on partial zero-emissions vehicles (which include EVs). Check with your dealer for specific information about battery life and warranties.

Introduction to the Design Process

Accreditation Board for Engineering and Technology (ABET) Definition of Design - • Engineering design is the process of devising a system, component, or process to meet desired needs. • It is a decision-making process (often iterative), in which the engineering sciences and mathematics are applied to convert resources optimally to meet a stated objective. • Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation. • Mechanical design means the design of components and systems of a mechanical nature—machines, products, structures, devices and instruments. • For the most part mechanical design uses mathematics, materials, and the engineering-mechanics sciences. • Additionally, it uses engineering graphics and the ability to communicate verbally to clearly express your ideas. • Mechanical engineering design includes all mechanical...

Initiatives launched by the Indian Government for Electric Vehicle or Promoting the Electric vehicle

Vehicular pollution is a major contributor to the rising levels of pollution in India. Electric vehicles have zero on-road emission and can minimise the production of greenhouse gasses. To promote the adoption of electric vehicles, the Department of Heavy Industry formulated the FAME India Scheme (Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles in India) in 2015 for the initial period of two years, with the first phase starting in April. According to an official press release , the Phase-I of the Scheme was extended to March 2019. In this phase, about 280,000 hybrid and electric vehicles were supported by way of a demand incentive amounting to about IN 359 crores (about US $50.5 million). This resulted in saving around 50 million litres of fuel and the reduction of around 124 million kilograms of CO2. Phase-I saw the development of about 500 charging stations across the country. Also, Energy Efficiency Services Limited (EESL...
