1. You want to drive with a Lithium Polymer Cell with 3.2 Ah and weighing 70 g. Which of the following configurations would be allowed by the rules? Hint: Unorm = 3.7 V, Umax = 4.2 V

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. 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)

6. Your BSPD has been triggered although the driver did not touch the driving pedal. What could have gone wrong? (multiple choice)

7. 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.

8. 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.

Assume the run was completed perfectly along the center line of the circles. What was their average speed during this record run? Give answer to two decimal places in mph.

3. 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.

10. The previous season you could recuperate only 25% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 63% of the initially stored energy.  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.
