Quiz „Electrical“

1 / 10

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.

2 / 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

3 / 10

Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)

4 / 10

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

5 / 10

Which of the following statements about LV battery packs with lithium based chemistry other than LiFePo4 is not true?
