IITRMS Newsletter March 2013
Citation preview
We are extremely delight-ed to mention that our team has successfully re-served the place in the competition. A Business Logic Plan was submitted mentioning basic design concept and a market strategy. Our plan was accepted and we got con-firmation along with the news that there are total 149 teams from 32 coun-tries registered in the com-petition and only IIT Roor-kee team is entering with a Hybrid Electric car. This is certainly a matter of pride for our team, IIT Roorkee and all the stakeholders.
Such huge project cannot see smooth operations without help and support of its well-wishers. We are highly thankful to Unitech Machines Ltd. and Rock-man Industries Ltd. for their continued their sup-port to our team. Again, they have sponsored the CNC machining for our complex aluminium hubs, uprights and other parts.
Special thanks to :
Mr. C. M. Hatwal (Plant Manager, Unitech Ma-chines Ltd.)
Mr. Sandeep Kamboj (Deputy Manager, Unitech Machines Ltd.)
Mr. Satish Banarasi (Plant Head - Haridwar, Rock-man Industries Ltd.)
Mr. P. Mishra (Assistant Manager (Engg. & Design) Rockman Industries Ltd.)
Again we can’t think of moving ahead without the support of our beloved alumni. We heartily thank our alumni whose timely
contribution in project funding during the past month lead to purchase of crucial components within time. Thanks a lot to
Mr. Ashok Soota (1963, Electrical Engineering) Chairman, Happi-estminds Technologies Ltd.
Mr. Sunil Pahilajani (1984, Mechanical) Man-aging Director, Greaves Cotton Ltd.
Mr. Om Prakash Goyal (1967, Chemical)
Mr. Sachin Rajpal (1997, Computer Science)

We are highly thankful to SAAR and Prama Jyoti Founda-tion for facilitating the contribution of Mr. Sunil Pahila-jani for our project. Since its inception, SAAR has been supporting the lIT Roorkee students by enabling them to showcase their projects to alumni and encouraging the alumni to contribute in the project funding. Not only have this but various other student projects in the cam-pus benefitted from SAAR.

IIT Roorkee Motorsports
International Conference 'Advances in Chemical Engineering- 2013' and the Alumni meet was organized by Chemical Engineering Department from 22nd to 25thMarch as a part of its Golden Jubilee Celebration. This turned out to be a great platform for our team to let the alumni know about our project. The event was marked by presence of around 100 alumni from India and abroad.
Mr. Pramod Saxena, 1975 Chemical (Chairman, Oxigen Services Ltd.), who is also one of the sponsors, visited the workshop along with three other friends of 1975 batch and had a closer look to our efforts. We explained the project, car design as well our vision for the team. They appreciated our hardwork and wished good luck for the competition.

Motor and Controller
Electric motor is the prime mover of the power-train and has to be selected such that it could cater to torque and power requirements for the vehicle at all the times given the maximum acceleration and velocity of the car.
Its selection includes consideration of efficiency, ease of control, availability, cost, the ratings of continuous power, peak power and peak torque required for the vehicle.
The process of motor selection requires a number of iterations based on the differences between the available options and the requirements.
The motor controller should regulate the power from the battery and engine generator to feed power to the motor such that motor runs as per the command from the driver.
Battery with Battery Management System
The battery is selected for higher energy density and better cycle life. These factors suggest the use of Lithium Ion battery.
The design of the battery requires calculation of battery capacity. Important points for consideration would be maximum discharge current during acceleration and maximum charging current during regenerative braking and normal charging from generator.
The battery would be connected to a Battery Management System (BMS) which is responsible for balancing of voltage among each of the individual cells. It also prevents overcharging and undercharging of cells which is critical in case of Li-ion battery. Further the BMS continuously monitors the Battery State of Charge (SOC).
The BMS connects battery to contactors which are connected to motor controller. The contactors are turned on by the command from the motor controller and turned off through a matrix of protective switches applied at different points in the car.

For a team to achieve its goal, it is very important that all of its members perform to the best of their potential. Making a hybrid car from scratch and then taking it at the international level is not an easy task and an enormous input is required in terms of money, mind and matter. We students have been giving our best to fulfill the need of mind but to arrange the matter, we do not have sufficient money.
This is an effort to create a history in IIT Roorkee. At this stage, we invite you to become an active part of this grand project by including your name among those who supported and nurtured the project during the real times of needs. All your contributions will go a long way in enabling the team to participate in the competition. It would be an honor for us to recognize you as our team members as below:
B E C O M E A S P O N S O R ! ! ! IIT Roorkee Motorsports is a group of enthusiastic engineering students from IIT Roorkee who are involved in design and devel-opment of a prototype Plug-in Hybrid Electric Vehicle for the international competition Formula Student 2013. We have raised sufficient funds to build the car and take it to UK and now we need to raise funds for team travelling.
We request you to associate with our team and project as a sponsor. In return of your monetary or in-kind support, we offer attractive sponsorship benefits. Following slots are available for association:
