2. 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.

3. 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

4. Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)

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

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

7. 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
