Quiz „Electrical“
1. 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)
2. Which of the following statements is false regarding the difference between Lead-based batteries, Nickel-based batteries and Lithium-based batteries?
no solution currently
3. 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

7. You have an electric car with these specifications:
How far can you drive with one load? Give answer to nearest whol number in km.
8. 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

Knowing that you had 9.6 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 to one decimal place.
