A Research Work to Develop an E-Axle Generic DVP for the Indian Market Complying with Indian and International Standards 2024-26-0118

The electric vehicle market in India has tremendous growth potential in the upcoming years and decades, attracting numerous automotive manufacturers, including Tier-1 suppliers, seeking to participate in this growth phase. Electric powertrains used in e-cars on Indian roads comply with BIS and AIS standards. However, these standards alone do not provide sufficient clarity on the complete list of tests required for developing an e-Axle through all stages of development. Developing the e-Axle in-house for the Indian market poses a significant challenge for OEMs and Tier-1 suppliers, as it will play a crucial role in overall profitability at high volumes in the long term. Adhering solely to the BIS and AIS standards may prove insufficient in fulfilling the developmental prerequisites of an electric axle (e-Axle) system. A comprehensive list of Specific, Measurable, Achievable, Relevant, and Traceable requirements for any e-Axle must be fulfilled through Performance, Functional, Durability, and Robustness categories of tests. This paper examines various International and Indian standards related to e-Axle development and testing. Additionally, it proposes a solution in the form of essential tests for each test category (a generic e-Axle DVP). This approach incorporates the applicable tests listed in BIS and AIS standards, along with some other relevant tests taken from international standards. In the end, it serves as a guide for developing an e-axle that not only meets Indian test standards but also aligns with the well-established testing methodology of e-axles based on international test standards.
