Ownership
...
need non conductive material on the inside
strength
access cover
Battery Box Cover
possibility of adding ceramic fibre / ceramic blanket / ceramic paper on the inside to contain heat
able to service the battery modules
entire area above modules must be open (able to see it ) when cover is open
modules will be installed by lowering them vertically into their slots
Rear Electronics cover
during egress, this part will be climbed over by someone
must be strong to hold people’s weight
current goal: separating high voltage and low voltage sections inside rear electronics enclosure
there will be two supports inside the cover, running along the length of the catamaran
(will later update on this when CAD/structural is decided)
current proposal for CAD – Rear Electronics Enclosure Proposed Layout
...
access cover needs
power supply input
AUX battery input
USB ports for phone charging
Recap of ASC Battery Enclosure Regulations
Isolation
resistance measured between battery terminals and any portion of the solar car chassis shall be greater than the 1MΩ, for applied potential up to 500V
...
required to provide impound box that fully contains the battery enclosure
box must have provision such that an Officer can secure with a maximum of two locks / seals
must be constructed that it does not contain external hardware that can be removed to access the battery box without breaking the seal
Egress Regulation
Performance Requirement
shall define primary and secondary direction for egress
must be separated by at least 90 degrees and cannot be on the same side of the car
able to exit the car unassisted
should take no more than 10 sec for occupant’s primary direction and 15 sec for occupant’s secondary direction
...
making sure it is safe for occupants
conductive
make sure it does not over heated
making sure that HV and LV is separated inside the cover
making sure that it is able to support weight of the occupants
no harm to the occupants (ex. smooth surface)
and strong enough so that it does not effect the electronics inside
Prompts for areas of investigation include regulation risks (i.e. headlight brightness doesn’t meet regs), mechanical risks (i.e headlight melting from hight temperature), manufacturing/assembly risks (i.e how does headlight mount to aero body?)
