Applicability
Applies to Construction Equipment Vehicles fitted with electric power trains and manufactured for the Indian market from the stated implementation date.
Key requirements
- Meet AIS-174 safety requirements for the electric power train.
- Apply the requirement to applicable vehicles from 1 January 2025.
- Continue using AIS-174 until corresponding BIS specifications are notified.
- Maintain technical evidence supporting the vehicle type-approval application.
OEM impact
- Integrate high-voltage safety requirements into construction-equipment architecture and release gates.
- Update type-approval plans, technical specifications, manuals and variant matrices.
- Control changes to battery, power electronics, wiring and protection systems after approval.
Supplier impact
- Battery, connector, cable, inverter and protection-device suppliers need complete compliance evidence.
- Supplier design changes require early notification and vehicle-level impact assessment.
- Production controls should retain traceability of safety-critical high-voltage components.
Testing / homologation impact
- Testing and inspection should follow the applicable AIS-174 requirements and approved vehicle configuration.
- The test agency may require component reports, drawings, calculations and vehicle-level evidence.
- Approval extensions should address high-voltage component and software changes.
Action points
- Confirm every electric construction-equipment model has AIS-174 coverage.
- Close gaps in high-voltage technical files and production traceability.
- Align supplier change control with the type-approval extension process.
- Monitor BIS adoption that may replace the interim AIS reference.
Open questions
- When will the corresponding BIS specification be notified?
- Which component substitutions require approval extension?
- How should imported base machines and locally integrated electric systems divide compliance responsibility?
