  • add any penalties to these times
  • decide on the best time of Team A and Team B
  • slowest time between these two best times is T_team
  • fastest time between these two best times gets multipled by 1.25 and is T_max
  • use formula from FSG Rules 2023 D4.4.3

4. Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number

The previous season you could recuperate only 25% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 63% of the initially stored energy.  Knowing that you had 9.6 kWh of energy in your accumulator during the last season, how much energy must your new accumulator have, if you assume, that it’s the same length and speed? Give answer in kWh to one decimal place.
