Quiz „Electrical“
1. 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
2. Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)
See FSG rules 2023: T6.3
3. 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
4. You have an electric car with these specifications:
How far can you drive with one load? Give answer to nearest whol number in km.

9. 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. Calculate the force Fc working at point C.
Rax = 4kN, Ray = 10 kN
Rbx =5 kN, Rby = 8 kN
Moment equation around point D:
0 = -Fc x 1m + Rby x 2.5 m – 60 kN x 4 m + Ray x 5.5 m
Fc = -165 000 N
Fc = – 165 kN
