Electric rickshaw

Electric rickshaws (also known as electric tuk-tuks or e-rickshaws) have been becoming more popular in some cities since 2008 as an alternative to auto rickshaws and pulled rickshaws because of their low fuel cost, and less human effort compared to pulled rickshaws. They are being widely accepted as an alternative to petrol/diesel/CNG auto rickshaws. They are 3 wheelers pulled by an electric motor ranging from 650-1400  Watts. They are mostly manufactured in India and China, only a few other countries manufacture these vehicles. Battery-run rickshaws could be a low-emitter complementary transport for the low-income people, who suffer most from a lack of transport facility, if introduced in a systematic manner according to experts.

The electric automobile did not easily develop into a viable means of transportation. Research waned from 1920-1960 until environmental issues of pollution and diminishing natural resources reawakened the need of a more environmentally friendly means of transportation. Technologies that support a reliable battery and the weight of the needed number of batteries elevated the price of making an electric vehicle. In 1837, Robert Davidson of Scotland appears to have been the builder of the first electric car, but it wasn't until the 1890s that electric cars were manufactured and sold in Europe and America. During the late 1890s, United States roads were populated by more electric automobiles than those with internal combustion engines.

These rickshaws have a M.S(Mild Steel) tubular Chassis, consist of 3 wheels with a differential mechanism at rear wheels. The motor is brushless DC motor manufactured mostly in India and China. The electrical system used in Indian version is 48V and Bangladesh is 60V. The body design from most popular Chinese version is of very thin iron or aluminum sheets. Vehicles made in fiber are also popular because of their strength and durability, resulting in low maintenance, especially in India. Body design is varied from load carriers, passenger vehicles with no roof, to full body with windshield for drivers comfort It consist of a controller unit.They are sold on the basis of voltage supplied and current output, also the number of mosfet(metal oxide field effect transistor) used. The battery used is mostly lead acid battery with life of 6–12 months. Deep discharge batteries designed for electric vehicles are rarely used. Weight of the electric car has also been a recurring design difficulty in them.
