You have an electric car with these specifications:
How far can you drive with one load? Give answer to nearest whol number in km.
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.
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)
How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.
Q = I * t

no solution currently
Which of the following statements about the Tractive System Accumulator are wrong? (Multiple choice)
See FSG rules 2023. Correct answers:
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
Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)

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

A racing car rolls to a stop on a horizontal course with an initial speed of v. It decelerates only by friction with a rolling resistance of μF, which is supposed to be independent of the current velocity. What is the distance s the car needs to stop? v = 230mph, μF = 0.17, g = 9.81 m/s2. Give your answer in meters, rounded to four significant places.

density (rho) = m / V
A vehicle with the mass 190kg, wheelbase 1,56m and tyre static radius 222mm is weighed. Scales measure 83kg (front) and 107kg (rear) when the car measured on the perfectly flat ground and the same values when the front axle is elevated by 0,85m. What is the car’s COG height? Give answer to the nearest whole number in mm
Fb‘ = m*g (at rear axle while front tyres are lifted)
Fb = m*g (at rear axle while car standing on ground)
Fg = m*g (at COG)
L = wheel base
sin(θ) = H/L
r= radius of tyre
A spring in a car’s suspension has elastic potential energy store 226 J. If the spring constant is 8.1N/mm, find the extension. Give answer in meters to three significant figures.
E = 0.5 * k * e^2
Calculate the force Fc working at point C.
Rax = 4kN, Ray = 10 kN
Rbx =5 kN, Rby = 8 kN

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
