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.
