Electrical vehicles in india

Electrical vehicles in india
While electric cars were developed in the U.S. more than 100 years ago, on this continent and in Europe the greatest number of EVs are still found off-road, mainly for industrial, recreational, personal mobility and transport purposes. EVs fulfill an important role in these practical applications because of the evident need to eliminate indoor pollution. Only recently have EVs started to gain wider acceptance for on-road transportation.
In comparison, there is an urgent need to introduce EV alternatives to pollution-generating transportation in large metropolitan centers throughout the developing world. Vehicle emissions have created such serious health problems that public health concerns in several countries now dictate that EV technology is actually a necessity. Indeed, many cities around the world are forced to mandate the EVs to mitigate the explosive growth of poisonous two-cycle engine vehicles.
In the Indian subcontinent, there are a number of companies, predominately Indian, working on EV solutions to reduce the vehicle pollution problem. Curtis Instruments, Inc. is one of a few U.S. companies involved in these efforts. For the past 40 years, Curtis has worked with hundreds of companies and on thousands of EV applications in use globally. Five years ago, Curtis began to supply manufacturers in India and Nepal with components, including motor speed controllers, battery indicators, throttles and Curtis/Albright contactors. Today, Curtis is involved in most of the on-road EV development efforts in these regions.
India's pollution problem is one of the most serious in the world, and vehicular emissions accounts for two-thirds of it. The worst polluters on the road are the two-cycle engine vehicles, such as scooters, auto-rickshaws and tempos (a large auto-rickshaw that transports up to ten passengers). Many of these vehicles burn a gasoline and kerosene mixture and spit out up to 40 percent of its fuel as hydrocarbon emission. Already the largest market for two-cycle engine vehicles, India has the population growth and improving economic conditions that point to an explosive demand for more of these vehicles - and the EV alternative.
