Formula Student Japan
Formula Student Japan
Project Description
The project was Formula Student Japan 2019. I participated in that competition with the Rajshahi University of Engineering and Technology. An electric formula student car was designed and built by ourselves for participating in the competition. We were the first-ever Formula Student Team in our country. Previously we started with the project ‘Formula Student Japan 2017’ with a combustion engine vehicle. To cope with the new technologies and a new era of electric vehicles, we started a new project for Formula Student Japan 2019 with an Electric Vehicle.
Project Objectives
Design and fabrication of a fully electric formula student race car.
Participating in Formula Student Japan 2019.
Introducing Electric Vehicle technology inside Bangladesh.
Design and Engineering Simulation
Vehicle dynamics designing.
Designing chassis and FEA analysis.
Wheel hub, upright and wishbone designing and FEA analysis.
Developing vehicle aerodynamics by CFD analysis.
Integrating Electric powertrain.
Fabrication and Performance testing
Chassis, body and parts fabrication, sourcing and vehicle assembly.
Ensuring driver safety according to FSAE rules.
Vehicle performance testing.
In 2017, the combustion engine vehicle for that event was designed considering similar objectives and design considerations and achieved points for design report submission. But the team couldn't participate with the vehicle in the competition arena.
Developing Electric Powertrain by Vehicle Conversion
Developing Electric Powertrain by Vehicle Conversion
Other objectives
To design and integrate the electric powertrain components, including the PMSM motor, inverter, and battery system, into the existing vehicle.
To optimize the system architecture and control algorithms to ensure the highest level of efficiency and performance.
To test and validate the electric powertrain in real-world conditions to determine its reliability, range, and overall performance.
To monitor and analyze the performance data of the electric powertrain and make necessary adjustments to improve its overall efficiency and performance.
To develop a safe and user-friendly interface for the electric powertrain, making it easy for drivers to operate and monitor the system's performance.

Electric Bus Benchmarking
Electric Bus Benchmarking
Project Description
The Electric Bus Benchmarking project aimed to compare the performance of different electric bus models in terms of energy efficiency, driving range, and overall operating costs. The objective of the project was to provide valuable insights into the current market offerings and identify the best practices and technological advancements in the electric bus industry. The project involved conducting extensive field tests on a variety of electric bus models and collecting data on various parameters such as energy consumption, driving range, charging times, and maintenance costs. The collected data was then analyzed to determine the strengths and weaknesses of each electric bus model and provide recommendations for future improvements.
