Asia’s Biggest Solar-Electric Car Rally

(A chain event of International Solar Car Federation)

India’s First Solar Car Rally, where the participating solar cars runs on public transport roads such as express way covering around 150 KM distance for a day. It is the only solar car rally competition in India, which offers a platform to the engineering students to design the reliable, light weight, ergonomically sound electric cars that can run on public transport roads. The vehicles have the option of charging their battery pack using solar panel or via regenerative braking. This is to make these vehicles as sustainable as possible.

The aim of the competition is to provide platform to students for gaining the hands-on practical experience, while applying engineering theories studied in the classroom. In addition, students learn the art of management and teamwork, which are essential skills required in the ‘real-world’. These student teams are required to build a new vehicle from scratch year-after-year and seek sponsorship and donations by their own means to fund the project.

The challenge to the student team is to design and fabricate a prototype vehicle that best meets the goals and intents as stated per the Rules Book. Over the course of a seven day competition, a jury of experts from the motorsport, automotive and supplier industries judge the design, cost and business planning of all the teams to determine the best team and vehicle; in addition the team’s on-track performance demonstrate how well they hold up under real life conditions on roads.

Pre Virtual Round

Mentorship Program – Teams are required to attend workshop in which the technical committee members of the event demonstrate the importance of rules, about the vehicle design and dynamics and overall vehicle concept followed by the rulebook test. The workshop also gives overview on all the event rounds evaluations, reports, Technical Inspections, enhancement of track time and college level TI, etc.

Rulebook Test – The purpose of the rulebook test is to give overall understanding of all the rules and apply best engineering skills to design the vehicle as per the rules.

Static Round

Engineering Design: The concept of the design event is to evaluate the student’s engineering process and effort that went into the design of a vehicle, meeting the intent of the competition. Prior to the event, teams are required to submit an engineering design report and a design specifications sheet for evaluation. At the competition, vehicles must be presented for design judging in finished condition, fully assembled, complete and ready-to-race. The judges will not evaluate any vehicle that is presented at the design event in what they consider being an unfinished state and will award zero points for the entire design event.

Cost and Manufacturing: The objective of the cost and manufacturing event is to evaluate the team’s understanding of the manufacturing processes and costs associated with the construction of a prototype car. This includes trade off decisions between content and cost, make or buy decisions and understanding the differences between prototype and mass production. Prior to the event, teams are required to submit a Cost Report with a detailed Bill of Materials and supporting documentation. At the competition, vehicles must be presented for cost and manufacturing judging in finished condition, fully assembled, complete, ready-to-travel on road. The judges will not evaluate any vehicle that is presented at the cost and manufacturing event, in what they consider being an unfinished state and will award zero points for the entire event.

Business Plan: The objective of the BPP is to evaluate the team’s ability to develop and deliver a comprehensive business model which demonstrates their product – a prototype race car – could become a rewarding business opportunity. The judges should be treated as if they were potential investors or partners for the presented business model. The business plan must relate to the specific prototype race car entered in the competition. The quality of the actual prototype will not be considered as part of the BPP judging. To convince the potential investors or partners that the team’s presentation is worthy of their time, it is required that an executive summary is submitted before the competition. The executive summary should contain a brief description of the team’s business plan.

Qualification Round

Technical Inspection: Technical Inspection Standard & Driver Safety – Each vehicle would be inspected for compliance according to rules and regulation mentioned in ESVC 2024 rulebook. Vehicle must be presented for technical inspection in finished condition i.e. ready-to-run condition. Technical inspection will not be done if the vehicle is brought in an unfinished condition.

Weight Test: The weight of the vehicle is checked to ensure it is designed and manufactured as per the weight criteria given in the rulebook.

Rain Test: Rain test is conducted to ensure the electrical safety of the vehicle. During the rain test, the tractive system must be active, and the drive wheels must be a minimum of 10cm off the ground or removed from the vehicle. It is not allowed to have a driver seated in the car during the rain test.

Brake Test: The brake test is one of the mandatory Scrutineering/Inspection requirements which must be passed before the car will be allowed on track. During the brake test, All wheels should lock simultaneously and Car should not yaw more than 30 degrees in braking distance of 7 and track of 100 m.

Dynamic Rounds – Qualification

Acceleration Test: The acceleration event evaluates the vehicle’s acceleration in a straight line on a flat track patch. The cars need to accelerate from a standing start over a distance of 50 m on a flat surface.  This distance of 50 m must be covered within 10 second of the vehicle starting from the starting line. If a vehicle fails to cover this distance then the team will receive 0 points in the acceleration round and will be disqualified.

Hill Climb Test: This round is to judge the vehicle’s gradient climbing ability. The round involves vehicle climbing at slope steadily. Teams are required to complete track in 10 seconds.

Cross Pad Test: This round intent to checks the maneuverability of vehicle, measure the Vehicle’s cornering ability along with its suspension dynamics on a flat surface. Team vehicle will start from starting line and it should travel along the track overcoming all the obstacles in-between the track. Team is required to complete track in 30 seconds.

Solar Performance Test : This is to check the solar performance of used solar panels on the vehicle in static and dynamic conditions. Teams have to keep their batteries potential at nominal operating voltage. Then teams will be given a time period of 2 hour to charge their batteries using solar panels. Then teams will have to run their vehicle for 45 minutes. Both static and dynamic performance of the vehicle will be checked during the round.

Durability Test: Durability Test is designed to evaluate the overall performance of the car and to test the car’s durability and reliability of the car. The vehicle has to endure for 45 minutes continuously; the cars with prolong 45 minutes run without mechanical/electrical breakdown will be qualified for the rally.

Dynamic Rounds – Rally

ESVC Solar Car Rally: All the qualified teams as per the above mentioned qualified rounds will participate in the Rally. It will be 150 KM rally per day from Gr. Noida to Agra. There will be 2 Patrol Cars at each checkpoint. These patrol cars will make round to and fro between check points in order to ensure the safety of teams and act as rapid response team in case of accident or emergency. This vehicle will consist personnel’s from organizing committee with first aid. All team vehicles will accompany one team vehicle and escort vehicle with them. The escort vehicle will consist of safety equipment’s and kits. It will act as an emergency rescue vehicle in case of an accident. This vehicle will also act as navigator for the team. Also one person from organizing team will be present in the vehicle as – Observer and a team vehicle will consist of team members trailing the car and basic equipment’s which can be used to repair the car in case of emergency or breakdown. In between the overnight stays, checkpoint will be established at every 50 km of the course for the day. These check points will be there for the teams to take a maximum of 30 minutes break, and get their vehicle inspection.
