- Surge protection.
Labeling and Documentation
- AC Chargers must include clear labeling with:
- Manufacturer details.
- Input and output specifications.
- Safety warnings.
- QR codes for scanning warranty and support details (optional).
- User manuals in English and local languages must be provided.
Incentives and Subsidy Eligibility
To qualify for government incentives under schemes like FAME II, the chargers must:
- Meet the technical specifications outlined by the Department of Heavy Industries (DHI).
- Be manufactured or assembled in India, adhering to local content requirements.
Import and Customs Compliance (if applicable)
For imported components or EV chargers:
- Compliance with Indian customs regulations.
- Certification of origin and adherence to import duties.
By fulfilling these requirements, EV AC charger can ensure safe, efficient, and compliant operation in the Indian market. Always consult authorized testing agencies or certification bodies for detailed testing protocols and updates to standards. The EV AC charger plays a vital role in ensuring interoperability and adherence to these national standards.
For manufacturers, prioritizing the design and compliance of the EV AC charger is essential to meet these regulations while maintaining safety and efficiency. Advanced testing for the EV AC charger further strengthens its reliability across diverse climatic conditions in India. The integration of electric vehicle homologation ensures that these chargers meet international and domestic standards, reinforcing their role in the EV ecosystem. Electric vehicle homologation also addresses key aspects of safety and compatibility, ensuring seamless adoption of EV infrastructure in India. Whether for residential or commercial use, the EV AC charger ensures compatibility with various EV models and integration with India’s grid infrastructure.
By focusing on these rigorous guidelines, the EV AC charger supports India’s transition to electric mobility, providing safe and sustainable charging solutions nationwide. Electric vehicle homologation will continue to play a pivotal role in enhancing the reliability and global acceptance of India’s EV charging solutions.
