Study on the Undocumented Electric Vehicles in Bangladesh
The Electric Vehicle (EV) is a much discussed issue in Electrical Engineering. EVs like Tesla has been controversial for their significant expense and polluting effect of their batteries. There are a large number of EVs, likely much more than 100,000, in Bangladesh which are feasible, effective and yet undocumented. Due to their untested nature, the EVs have been prohibited from Dhaka's fundamental homes like Dhanmondi, Bashundhara, Uttara, Gulshan. Instead they are found in the rear alleys of Zigatola, Rayerbazar, Diabari and Sector 18. The fundamental issues about Electric vehicles are related to I) battery ii) charging iii) support (iv) recycling v) supply of electricity and renewable energy & vi) bulk energy storage. The vast majority of EVs in Bangladesh are three wheelers Easy Bikes (Tom-tom, Electric bicycle, Electric Rickshaw). The use of EVs has been discouraged as of now because of its high power consumption. There is no official information on how much power the electric vehicles in Bangladesh expend. Battery Run Three Wheelers exhaust around one gigawatt (GW) of intensity consistently, charged routinely through the private electrical cables without charging stations. Then again, Easy Bikes full charging expense is tk8 (every day), needs 6-8hours to completely charge and the limit of the battery is 48V20Ah. Tom-tom takes charging hour of about 10hours and working time of very nearly 10-12 hours. It needs 5 batteries to work. There are different sort of batteries, for example, 200A costing tk50k, 160A for tk45k and 120A for about tk40-42k. The battery keep going for about 6months to 1 year. The drivers pay 200 taka every day to charge the battery in the charging station. In electric rickshaws, lead acid batteries are utilized and the cost of the battery is about tk 18-20k, it's charging time is 6hours and works for practically 4hours. All of the electrical supply for this vehicles are unbilled.
