41) Given is a battery cell with an end-of-charge voltage of 4.2V, an average internal dis-charge resistance of 0.5mR and an average internal charge resistance of 0.7mR. 360 of these cells are used to build an accumulator in 120s3p configuration. This accumulator is used to drive an Endurance that takes 1440s. The car re-generated energy during 18% of the lap time with an average total accumulator charging current of 3A. 9% of the lap time the accumulator was not charged or discharged. Energy was sourced to the motors for the rest of the lap time with an average discharge current of 30A. How much energy is wasted during Endurance due to the internal resistance of the cells? NOTE: No other losses have to be taken into account. Wherever possible, average values may be used and simplifications may be applied. For example the influence of the internal cell resistance on the accumulator voltage should be neglected.
