1. Which of the following statements about LV battery packs with lithium based chemistry other than LiFePo4 is not true?
See FSG rules 2023 T11.7.7
2. Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)
See FSG rules 2023: EV5.3.4, EV5.4.6, EV5.5.12
3. The following processes have to be measured by the AMS. (Multiple choice)
See FSG rules 2023: EV5.8.1, EV5.8.1 & EV5.8.3, EV5.8.10
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
40% SoC -> 3.7V and 1.6 mΩ and 80% SoC -> 3.8V and 1.2 mΩ, total open-circuit voltage
71*3.7 + 71*3.8 = 532.5V
Total impedance = 71 * (1.6m/2) + 71*(1.2m/2) = 99.4mΩ
V*I = I^2*R * 80kW
I = 155 A
5. Three inductors are connected as shown in the following figure:
Given that L1 = 2L2, find L1 and L2 such that the equivalence inductance is L = 0.7 H. Give your answers in Henry, rounded to three decimal places separated by a comma (L1, L2)
6. Which statements about the travel of the driving pedal is correct
FSG Rules 2023: T11.8.1, T11.8.5
7. You want to drive with a Lithium Polymer Cell with 3.2 Ah and weighing 70 g. Which of the following configurations would be allowed by the rules? Hint: Unorm = 3.7 V, Umax = 4.2 V
8. Your BSPD has been triggered although the driver did not touch the driving pedal. What could have gone wrong? (multiple choice)
9. You have an electric car with these specifications:
How far can you drive with one load? Give answer to nearest whol number in km.
10. Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)

1. A 30 lbs model helicopter flying at 51 mph, calculate its kinetic energy. Answer in J to 3 significant figures.
KE=0,5 * m * v^2
2. A ball at a height of 20ft on Earth with a gravitational field strength of 9.81 N/kg, gained 284 J of gravitational potential energy. Calculate the mass of the ball. Give answer to two decimal place in kg.
E = m * g * h
3. For a horizontally positioned, non-insulated steam pipe with a length of l=3 m and a diameter of d_a=0.1 the convective heat loss Q_point is to be calculated. The temperature of the surrounding air is θ_f=30∘C and that of the outer wall surface is θ_w=170∘C.
Input the result in kW and round to two decimal numbers seperated by a point without thr unit (example: 145.35)
4. The given gearbox consists of two gear sets with wheels 1, 2 and 3, 4 respectively. The wheels are fixed to their shafts. Calculate the drive speed (in rpm) of wheel 4?
Given: n1=600 rpm, z1=18, z2=90, z3=24, z4=120
5. The kinetic energy of a 8 lbs 4 oz box as it was dropped reaching ground is 10125J. Determine the speed as it lands. Give answer to one decimal place in m/s.
KE = 0.5 * m * v^2
6. Calculate the force Fc working at point C. Give answer in kN rounded to one decimal place.
Forces at point A: Rax = 3kN, Ray = 9kN, Ma = 10kN/m
Moment Equation around point D:
0 = -Fc x 1m – (60kN x 3m) x 4m + Ray x 5.5m – 10kN/m
Fc = -190 510 N
Fc = -190.5 kN

10. You would like to drink a cup of very hot coffee with milk early in the morning, but you are in a hurry and have only 5 minutes until you have to leave for work. At which time after brewing should you add the cold milk to the coffee and stir in order to decrease the temperature of the mixture as much as possible: a) 0 minutes (immediately), b) 2 minutes, or c) 4 minutes? Suppose that the stirring can be done instantaneously and that you need the last one minute for drinking.
brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature 0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
Please enter only the letter of the corresponding answer
The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait. So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.
