SUN Mobility Secures Industry-First AIS-038 Certification for Heavy Vehicle Swappable Batteries
On March 26, 2026, SUN Mobility announced a major milestone by receiving the industry’s first AIS-038 certification for an indigenously designed and developed swappable high-voltage battery platform. This platform is specifically tailored for heavy commercial vehicles, including trucks and buses.
The certification was granted by the Automotive Research Association of India (ARAI) in Chakan. This rigorous testing process successfully validated the platform’s reliability, safety, and performance for commercial use.
Key Features of the Swappable Battery Platform
- The platform features a modular, scalable, and OEM-agnostic architecture.
- It operates in the 660V high-voltage category.
- It is available in 50 kWh and 100 kWh variants, along with combinations of these capacities.
- The design supports both new vehicle integration and retrofit applications, allowing operators to optimize energy capacity.
- It is compatible with small, medium, and heavy commercial vehicles.
Impact on the Commercial EV Ecosystem
The timing of this certification serves as a critical inflection point, aligning with the government’s PM e-DRIVE scheme, which accelerates the procurement of electric trucks and buses. By offering a verified and scalable solution, SUN Mobility aims to meet the growing demand for cost-effective and reliable EV options to decarbonize hard-to-abate sectors.
SUN Mobility’s journey began in 2019 with the introduction of India’s first swappable battery system for buses. Since then, the company’s heavy electric vehicle (HEV) business has filed over 160 intellectual properties, with more than 40 already granted. This indigenous development underscores India’s capability to manufacture EV technology that meets global safety standards, directly supporting the vision of an Aatmanirbhar Bharat.
