SUN Mobility has achieved a major milestone in India’s electric mobility sector by becoming the first company to receive AIS 038 certification for an indigenously developed swappable high-voltage battery platform designed for trucks and buses.
The certification was granted by Automotive Research Association of India after rigorous testing validated the platform’s safety, performance and reliability for commercial vehicle applications. The development marks a significant step forward in accelerating electrification in India’s heavy commercial vehicle segment.
SUN Mobility’s journey in battery swapping began in 2019 with the introduction of India’s first swappable battery system for buses. Since then, the company has built a comprehensive high-voltage ecosystem tailored for heavy electric vehicles (HEVs), including both buses and trucks. The solution is aimed at reducing downtime, eliminating range anxiety and improving operational efficiency and financing flexibility for fleet operators.
The newly certified platform is available in 50 kWh and 100 kWh variants, operating in the 660V category. Its modular and OEM-agnostic design allows integration into new vehicles as well as retrofit applications, enabling operators to customize energy capacity based on specific operational needs.
The announcement comes at a time when India’s commercial EV ecosystem is gaining momentum, supported by government initiatives such as the PM e-DRIVE scheme, which is accelerating the adoption of electric buses and trucks. SUN Mobility’s certified platform is expected to play a crucial role in meeting the rising demand for scalable and cost-effective EV solutions.
Speaking on the achievement, Ashok Agarwal, CEO of SUN Mobility’s HEV Business, said that swap-enabled heavy electric vehicles will be key to driving EV adoption at scale. He added that the certification reinforces the company’s mission to democratize electric mobility through Made-in-India solutions.
Naveen Chopra, Chief Technology Officer and Chief Operating Officer (Manufacturing Operations), highlighted that the platform addresses the complex performance and reliability requirements of heavy commercial vehicles while demonstrating the robustness of indigenous engineering capabilities.
With over 160 intellectual property filings and more than 40 patents already granted, SUN Mobility continues to strengthen its position as a technology leader in EV infrastructure. The certification also underscores India’s growing ability to develop globally competitive clean mobility solutions, supporting the broader vision of self-reliance in advanced automotive technologies.
