You have an electric car with these specifications:

  • ten 12V batteries
  • constant velocity of 80 km/h
  • flat road (friction 1.2kN -> aerodynamic load included)
  • load for battery 160 Ah

4 / 10

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

5 / 10

How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.

In a cylinder, air is compressed isothermally at ambient temperature (θ_U=20∘C) to .
Calculate the change in the specific entropy of the air in the cylinder.
Round to two decimal numbers sperated by a point. Input in J/(kgK). (Example -365.26)

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

5 / 10

During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.

CL=3.8     CD=1.2     A=1 m²     rho=1.1 kg/m³     L1=50 mm     L2= 100 mm     H1= 125 mm     H2= 165mm

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
