CHAPTER 7 COMPETITOR VEHICLES AND VEHICLE SAFETY EQUIPMENT Appendix 11- Electrified Vehicles
1. Technical
1.1. The term Electrified Vehicle(‘ EV’) is used in these regulations to cover all forms of Electrified Vehicles( including those defined in FIA Appendix J – Article 251): mild Hybrid Electric Vehicle(‘ mHEV’), Hybrid Electric Vehicle(‘ HEV’) / Full Hybrid Electric Vehicle( FHEV), Plug-in Hybrid Electric Vehicle( PHEV) and Electric Road Vehicle(‘ ERV’) / Battery Electric Vehicle(‘ BEV’).
1.2. High Voltage( HV) shall be as defined in FIA Appendix J Art 251 3.1.10( from ISO 6469-1:2009): > 30V AC and ≤ 1000V AC or > 60V DC and ≤ 1500V DC.
1.3. An EV may contain a High Voltage( HV) or Low Voltage( LV) propulsion system.
1.4. As a general principle in all Technical Regulations it is prohibited to carry out any tuning or modification that is not specifically permitted. The fact that some modifications are mentioned as prohibited does not imply that others are allowed.
1.5. Changes to these Technical Regulations made on grounds of safety may be enforced immediately without notice.
1.6. These General Technical Regulations are for individual Vehicle builds. Championships for specific Vehicles not in accordance with these regulations may apply for approval which will be considered at the discretion of the ASN.
1.7. Permitted Electrified Vehicle Types( App. 13 Chart 3)
1.8. These regulations apply to any modified National Type Approved or Bespoke / prototype EVs intended for Competition use. Standard and unmodified production EVs are subject to the existing requirements of the ASN and the FIA where applicable.
1.9. A Standard Vehicle is defined as built by the manufacturer in accordance with its homologation / type approval with no modifications or alteration of the Vehicle structure, powertrain, or electrified propulsion system. E. g., Competition seats using the original mounting points and fasteners are permitted. A ROPS requiring fastening to the Vehicle structure is prohibited.
1.10. A Modified Vehicle is a Standard Vehicle with non-powertrain modifications only( including fitment of safety equipment including ROPS which alters the Vehicle structure). No modifications to the internal combustion engine( ICE) and / or electrified propulsion system are permitted other than non-Powertrain HV systems( such as HVAC etc.) which may be removed. The exposed HV connectors must be capped with suitable blanking plugs that maintain HVIL functionality. Driver displays, and powertrain cooling systems may be replaced with alternative commercially available parts.
1.11. A Bespoke Vehicle is one designed and constructed from scratch including prototypes. Only Bespoke BEVs are permitted. Bespoke includes prototype or otherwise unique competition Vehicles.
1.12. A production Vehicle with the ICE powertrain replaced by an electric one is classified as Bespoke. 1.13. Hydrogen powered fuel-cell hybrid and electric Vehicles are prohibited.
1.14. These Technical Regulations cover all EVs, but not all regulations apply to all Vehicles. For example, the HV safety related requirements do not apply to an mHEV, as these operate at a nominal DC voltage of 48V which is lower than the 60V DC limit( Table 1).
1.15. The discipline-specific Sporting Regulations will determine which category of EVs are allowed to compete in which discipline.
1.16. Except for Standard EVs in non-Speed Events all EVs must be in possession of a valid Vehicle Passport to compete. Modified and Bespoke EVs must undergo and pass a Vehicle Passport inspection irrespective of discipline or Category.
1.17. Electric Vehicle Passports will be issued by the ASN.
