1) The team decides to implement the TSAL circuit and the Discharge Circuit in the same PCB. Given that the maximum voltage of the team is 357V, what is the maximum permitted distance between the circuits when there is a cut in the board.

3.2mm

6.4mm

9.5mm

None of the above

2) What is NOT true about the TSMPs.

TS+ and TS- must be directly connected to the positive and negative pole of the accumulator container

TS+ and TS- wires must be orange

Next to the master switches an LV+ and an LV Ground measurement point must be installed

If the Maximum Voltage of the team is 357V the current limiting resistor must be between 5kOhm to 15kOhm

3) What is NOT true about the TSAL (Tractive System Active Light)

The TSAL must be lower than 150mm from the highest point of the main hoop

Software control of the TSAL is not permitted

If the accumulator isolation relays (AIRs) are open the TSAL must be green in color and continuously illuminated

The TSAL must not be able to contact the drivers helmet in any circumstances

What is true about the steering wheel of Iris’ car which is made from carbon fiber (semiconductive material):

It must have a resistance below 5 Ohm to LVS Ground

It must have a resistance below 0.3 Ohm (measured with a current of 1 A) to LVS ground

It does not need to be grounded

5) If the segment of the accumulator container has a configuration of 16s2p (16 series and 2 parallel) lithium based cells, how many temperature sensors must be installed in every segment (the parallel cells are considered as one cell)

6) Which ONE of the following Relays is Normally Closed in the de-energized/disconnected state.

IMD Relay

AMS Relay

Discharge Relay

Precharge Relay

What is true about the charger

The charger must be orange

The emergency stop button must have a minimum diameter of 40mm

The TSMPs of the charger must be connected to the charger’s output

When charging the IMD must be live and must be incorporated inside the charger

What is NOT true about the maintenance plugs

It must not be physically possible to electrically connect the maintenance plugs in any way other than the design intent configuration.

Maintenance plugs must not require tools to separate the TS accumulator segments.

Maintenance plugs must be orange

Maintenance plugs must be non-conductive on surfaces that do not provide any electrical connection

What is NOT true about the accumulator indicator light

Software control of the indicator is permitted

The indicator must be clearly marked with “Voltage Indicator”

Instead of a LED Indicator a Voltmeter can be used

If a team has maximum high voltage 100V, the indicator must be non-illuminated when the voltage of the accumulator container is 55V

Which sentences are NOT true about the accumulator container

The TS accumulator container must consist of electrically insulating internal vertical walls with a minimum of 70 % of the height of the external vertical walls

All TS accumulator container materials must be fire retardant

The AIRs and the Main Fuse must be separated with an electrically insulated and fire retardant material

Each TS accumulator segment must not exceed a maximum static voltage of 100 VDC, a maximum energy of 6 MJ and a maximum mass of 12 kg

What is true about the accumulator container

The accumulator container must be designed to withstand 40g acceleration in the longitudinal direction (forward/aft), 20g in the lateral direction(left/right) and 20g in the vertical direction(up/down)

Tabs of pouch cells must not carry mechanical loads

Every wire used in an TS accumulator container, regardless of whether it is part of the LVS or TS, must be rated to the maximum TS voltage.

The accumulator container of Aristurtle weights 66.5kg

What is TRUE about the HVD

An untrained person must be able to remove the HVD within 10 s when the vehicle is in ready-to-race condition.

The HVD does not need to be inside the Rollover Protection Envelope

A dummy HVD connector must be always attached to the pushbar

The HVD must be clearly marked with “High Voltage Disconnect”

What is TRUE about the Data Logger

The data logger must be supplied directly from the TSMS

The data logger can be inside or outside the accumulator container

The data logger must be in an easily accessible location so that it is possible to insert, remove or replace it within 15 seconds in ready to race condition

The TS voltage sense connection of the data logger must be directly connected to the most positive AIR(s) on vehicle side

What is TRUE about the tractive system wiring

Every TS connector outside of a housing must include a pilot contact/interlock line which is part of the shutdown circuit

The Inverter’s wires of Aristurtle’s car must have an interlock line which is part of the shutdown circuit

Any shielded cable must have the shield grounded

All TS wiring that runs outside of TS enclosures must be orange and be securely anchored at least at each end so that it can withstand a force of 200 N without straining the cable end crimp
