Abstract:
The design of a cost effective efficient charge controller for the electric rickshaw in
Bangladesh has been done in this work. Electric Rickshaw are one of the most common
form of electric vehicles in Bangladesh. Due to its several advantages, it has become very
popular in rural areas. As electric rickshaw is run by the battery, charge controller plays
an important role. The charge controllers need to have a high efficiency and different
protection systems. Due to the inefficiency of charge controller, electric rickshaw
consumes a lot of power that creates problems in the power sector. Quality of charge
controller available in Bangladesh has been studied here to evaluate their performance.
Designing is done in such a way that it senses how much charge is stored in the battery
and according to it, charging voltage changes. Various safety features have been
incorporated in the design to protect the battery as well as the charger itself. Simulation
has been done using PROTEUS software. Tap changing transformer has been used for
controlling in collaboration with Micro-Controller. The simulation results show that the
design system is efficient and effective in charging the batteries. The charging system can
be used to minimize the energy losses while charging and lengthen the life of the
batteries in the electric rickshaws of Bangladesh.

Description:
All praises be to Allah, the merciful, the beneficent.
We would like to express our heartiest gratitude and profound respect to our thesis
supervisor Dr. Md. Ziaur Rahman khan, Professor, Department of Electrical and
Electronic Engineering (EEE), Bangladesh University of Engineering and Technology
(BUET) for his continuous guidance, generous help, suggestions, inspirations and
wholehearted supervision throughout the process of this work. We feel grateful to him for
giving me some sufficient freedom and having faith in our capabilities, which made the
thesis work much effective for us. His passion and dedication to academic research has
motivated us to push our boundaries harder and excel at our research work, which we
believe, will inspire us to be a better researcher in future.
We would like to thank our parents and dedicate our thesis to them. They have been the
encouragement behind our every successful endeavor. This thesis work is not an
exception and this would not have been completed without their constant support and
inspiration.
Finally, we put forward our humble gratitude to all our colleagues, friends and wellwishers
for their help, supports and words of encouragements during our thesis work.
