1. For this Wheatstone Bridge based NTC temperature measurement circuit, which is the lowest voltage measurement (VAB) that is possible to obtain at 60ºC? (NTC B: 3435 +/-1%) Give answer in Volts rounded to two decimal points.
2. Your team is considering two languages, Verilog and VHDL, for programming an FPGA. Which languages could be used?
3. Which of the following statements about the Tractive System Accumulator are wrong? (Multiple choice)
See FSG rules 2023. Correct answers:
4. The previous season you could recuperate only 27% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 69% of the initially stored energy. Knowing that you had 6.3 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
E_new = E_old * (1+0.27)/(1+0.69)
5. 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
6. 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
7. Your BSPD has been triggered although the driver did not touch the driving pedal. What could have gone wrong? (multiple choice)
8. How long will it take to discharge C1 below 60V using the following constant current sink if it is initially charged at 565V? (MOSFET’s VGSth: 4V) Give answer to two decimal places in secs.
Circuit’s current: MOSFET will operate in linear zone, close to the activation voltage. Therefore, as VGSth is 4V, VS can be taken as 8V. From these 8V and the 47R current limiting resistor, the discharge current of the circuit will be 8/47->0,17A As the constant current discharge of a capacitor depends on capacity, as V=i·t/C-> t=V·C/i=(565-60)·0,0012/0,17=3,56s
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. A thin circular, isolated wire made of copper with radius R lies on a table with its ends connected to a Volt meter. Another, straight wire lies exactly along a diameter of the circular wire, connected to an alternate current source i(t) = I0 sin(wt). The experimental setup is shown in the following Figure:
Which effective voltage Ueff does the Volt meter display? R = 10 cm, maximum current I0 = 1 A, f = 50 Hz. Give your answer in Volts with three decimal places
The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.
