Your team has calculated from your vehicle model simulations that the minimum required battery pack energy to finish the Endurance is 6,5 kWh. Unfortunately, this year regenerative braking from electric motors will not be used during Endurance. Which of the following battery packages provides enough energy to finish the Endurance and also fulfils all requirements set in rule EV 5.3.2? Note 1: when calculating the total energy of the battery package use the nominal battery cell voltage. Note 2: when calculating the energy of the battery segment to verify rule EV 5.3.2 use the indicated battery cell voltage specified in the rules. Note 3: when calculating the segment mass, assume all mass is caused by the battery cells.

Battery Cell Supplier A. 5 segments connected in series. Each segment contains 21 cells connected in series and 3 connected in parallel (21s3p).

Battery Cell Supplier A. 8 segments connected in series. Each segment contains 15 cells connected in series and 2 connected in parallel (15s2p).

Battery Cell Supplier B. 5 segments connected in series. Each segment contains 30 cells connected in series and 4 cells in parallel (30s4p).

Battery Cell Supplier B. 8 segments connected in series. Each segment contains 10 cells connected in series and 6 cells connected in parallel (10s6p).

Does the race car have to be part of the BPP?

Yes, the BPP has to cover the actual race car entering the competition.

No, the business case doesn't have to be related to the race car entering the competition.

No, the business idea has to be comprehensive and a rewarding opportunity to the potential investors.

Yes, the BPP has to cover a race car for a weekend racing driver.

Time keeping has registered an uncorrected elapsed driving time of t=24,30 min for the fastest endurance vehicle and it knocked 7 cones (DOO). The lowest corrected used energy of all teams who are able to score points in efficiency is E=5,32 kWh. Our team has an endurance uncorrected elapsed driving time of t=28,20 min and we made 1 off-course (OC). Our corrected used energy is E=6,08 kWh. The best efficiency team has an efficiency factor of E=0,85 and the worst efficiency team has an efficiency factor of E=0,48. Which is our Efficiency Score?

What is true about the Engineering Design Event?

Drawings in the EDR may also be renderings

A maximum of 5 points are awarded for the Design Spec Sheet (DSS)

Any EDR that exceeds 8 pages will not be reviewed at all

Judges may be selected on the basis of the quality of the EDR
