FSAE Rules


The 2015 Rules are posted below. *2nd Revision, September 17, 2014

*Student teams be advised this is a newer revision of the rules dated September 17, 2014 as the following rules (T3.5.5 and T3.20.2.a) have been revised due to recent clarification from rules inquiries; it was not the intent of the committee to exclude some of the design options with the wording therefore it has been revised. Also it has been recognized that rule T3.34.4 was accidentally deleted during the revision process. These changes can be found highlighted in yellow and are the only additional changes since original rules publication.

**Additional EV rules may be revised/clarified in future rules release but should not affect design of team vehicles. Committee is reviewing additional changes based on 2014 FSG/FSE competition.

2015 Rules Clarifications

Published 11/19/14

IC4.4.4 Battery packs based on Lithium Chemistry
LiFePO4 batteries will be accepted without over voltage, under voltage and over temperature protection, however all other aspects of IC4.4.4 must be met. Short circuit protection must be provided internal or external to the battery.

Commercially manufactured LiFePO4 batteries will be accepted without over voltage, under voltage and over temperature protection, however all other aspects of EV3.7.4 must be met.

IC4.6 Voltage limit for IC vehicles
It was not the intention of the rules committee to introduce more restrictive voltage limits within the IC category which prevents the use of OEM 12V charging systems. If the charging system is OEM and designed for a DC battery voltage less than 60V then the 25VAC limit of rule IC4.6 does not apply, however the system must either use the stock wiring between the generator and the rectifier, or this wiring must be rated to at least the maximum output voltage of the rectifier.
If student teams are electing to build a charging system then rules must be followed.

IC1.7.3 Clarification
Pop-off (aka blow-off) valves located between the compressor discharge and throttle body that vent directly to atmosphere are permitted for turbochargers and superchargers.

Note that these valves will be carefully inspected in Tech for compliance to the intent of rule IC1.7.3 which is only to relieve surge when the throttle is closed and not to allow flow to bypass the restrictor under non-boosted conditions. All flow for the engines must pass through a single intake restrictor per rule IC1.1.3.

EV9.2 Failure Modes and Effects Analysis (FMEA) Clarification
The following supersedes the 2015 Formula SAE rules for the 2015 Formula SAE Electric competition (in Lincoln, NE) only.
• Teams may use their frame constructed for the 2014 Formula SAE Electric event if the frame meets or is modified to meet the applicable FSAE 2015 frame rules (Section T3 or Section AF). Rule A6.6.2 will not apply.
• The Failure Modes and Effects Analysis (FMEA) per EV9.2 does not need to be submitted. References to the FMEA in rules A5.3.6, EV2.3.11, EV2.4.6, T7.1.10, and S2.4 may be ignored.

Please note that the deadline for the required Electric Safety Form remains January 12, 2015.
