How do you calculate the efficiency of an electric car?
We know that 1 Wh = 3600 J, so 90 Wh = 324,000 J. And the power plant efficiency, conversion and transmission losses in electricity in India are 70\% or more. So an Indian electric car @ 90 Wh/km has an efficiency of 1/(3600 divided by (100\% minus 70\%)) x 10^6 x (1/90) km/Wh = 0.93 km/MJ.
What is an energy efficient vehicle?
Energy efficient. EVs convert over 77\% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12\%–30\% of the energy stored in gasoline to power at the wheels.
How does the economic viability of electric vehicle affect how customers?
The economic viability of electric vehicle affects how customers accept the vehicle. Initial cost (especially due to the battery) of an electric vehicle is more than that of conventional vehicles. EVs get accepted widely if they become cost competitive.
How feasible is it to get an electric vehicle?
A large number of questions arise when one plans to get an electric vehicle. Answers for the economic feasibility of electric vehicles would be as follows. Electric vehicles are becoming a close competitor with conventional Internal Combustion Engine vehicles in terms of performance, cost, etc.
What are consumers’ preferences on electric vehicles?
Consumer preferences on electric vehicles . Consumers’ EV preferences are shifting. The share of global consumers that would consider purchasing an EV is on the rise. In the United States, between 10 and 30 percent of consumers indicated their preference to consider an EV as their next purchase on national surveys. 1
Do OEMs make profits from the sale of electric vehicles?
However, there is a problem: today, most OEMs do not make a profit from the sale of EVs. In fact, these vehicles often cost $12,000 more to produce than comparable vehicles powered by internal-combustion engines (ICEs) in the small- to midsize-car segment and the small-utility-vehicle segment (Exhibit 1).
