Quiz „Electrical“

1 / 10

1. 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
  • efficiency of 80% (Motor)

How far can you drive with one load? Give answer to nearest whol number in km.

2 / 10

2. 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

3. Which of the following statements about the Tractive System Accumulator are wrong? (Multiple choice)

4 / 10

4. 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)

An air stream dot{M}_L = 5.5  kg/s, cp_L=1 kJ/(kgK) is to be heated in a plate heat exchanger from θ_L′=20∘C ′ to θ_L′′=150∘C. For this purpose, a flue gas stream dot{M}_R = 7.22, cp_R=1.1 kJ/(kgK) with a temperature of θ_R′=300∘C is available. The overall heat transfer coefficient is k=15 W/(m^2*K).
