Fault Indicator/Strobe Light 

Description: The strobelight contains 4, 3 watt LED’s and is powered by a 12V line. It has 4 wires for setup although we only need to use 3. Outside of power and ground, the other 2 wires are for sync and pattern.
Usage: The sync wire is if we are using multiple strobelights that must strobe at the same time. The pattern wire must be shorted with power if the pattern is to be changed. Once it is set to a pattern, it remembers the pattern with on board flash memory.
Reason: The strobelight is used to alert other vehicles on the road that the car is dangerous and to avoid it. It is also required under the ASC regulations(9.4.G).

Description: This fuse is meant to protect the battery in the event of a short circuit in case the BPS cannot react fast enough. This fuse is rated for 60A and 150VDC and is what is used in the BPS.
Usage: It is placed on the high voltage line between the contactor and battery pack.
Reason: According to the ASC regulations(8.5.A), the fuse must be rated for less than 200% of the maximum expected current draw(which for this system is around 60A). The rating must also be for more than 75% of the maximum current capacity of the wire(tbd).

Description: Turn car on and off.
Usage: Control power delivered to load (HV+), power delivered to battery (ARR+), GNDPWR(HV-) connections by powering contactors. They are normally open and have a turn on current around 4A (when tested). They have a sense pin that returns whether the contactors are on or off. If the kill switch is pressed, the Contactors power is removed and the sense line is pulled low. The sense line must be read to turn on the strobe light of the car.
