We are extremely delighted to mention that our team has successfully reserved 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 confirmation along with the news that there are total 149 teams from 32 countries registered in the competition and only IIT Roorkee 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 Rockman Industries Ltd. for their continued their support to our team. Again, they have sponsored the CNC machining for our complex aluminium hubs, uprights and other parts.

TEAM INTERACTION WITH ALUMNI IN CHEMICAL ALUMNI MEET 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.
Mr. Pramod Saxena and friends with the team members in our workshop.
VEHICLE DESIGN METHODOLOGY 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.
ARE YOU AN IIT ALUMNUS ? BECOME OUR ALUMNI TEAM MEMBER... 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:
