Suppose that the refrigeration of our Packacan handle 1kW of heat dissipation. If, approximately, 9% of the energy that comes out of the Accumulator is lost in form of heat, what is the nominal regenerative current (constant value) we can allow to flow into the Accumulator when braking? Assume that, when accelerating, the car is working at aconstant current of 25 Amps, andthat it is accelerating 63% of the time, braking a 30% and the remain percent accounts for going with its own inertia (so regeneration is not active). For a low estimate, assume that the total voltage of the Accumulator is 550 V RMS.

How many people are allowed to disconnect the hvd of a car?

The ESO’s

People designated for that function prior to the competition

Any person, be trained or not for that should be able to do it.

All answers are false

Your team has a steel suspension support welded to the Front Bulkhead Support Structure. With a lower e/D ratio than 1,5. Does this support pass the rules?

Yes, because it is a suspension support.

No, any bolted joint in the primary structure using either tabs or brackets must have a ratio e/D of 1,5 or greater.

Yes, only if the support is a tab.

Yes, is not important because the support is welded to the primary structure and no bolted.

The bearing D has 0,3 [kg] of mass, α = 40 [º] and de bar ABC rotates with a constant angular speed of 5 [rad/s]. Supposing that there aren’t friction forces, calculate the radius r that makes that the bearing D doesn’t slide for the bar

R = 936 [mm].

R= 468 [mm].

R = 234 [mm].

R = 117 [mm].

What is a SCS signal?

It is any sensor signal.

It is any accumulator signal.

There is not any definition of SCS signal.

None of the above.

If the TSAL light is blinking in red but there is no relay closed, no voltage outside the accumulator or no voltage on the inverters capacitors, what may be happening?

Your design is wrong.

It is not OK, something is not working properly.

A signal that may influence in the TSAL light is disconnected.

There is no GLVS supply.

What is a bypass capacitor?

It is used to eliminated the DC component, normally it is used in series with a voltage source to get an AC voltage source.

It is any capacitor used in any RC filter.

It is any capacitor used in power electronics.

It is used to reduce the noise of voltage signal/source.
