Amara Raja Advanced Cell Technologies (ARACT), a subsidiary of Amara Raja Energy & Mobility Ltd, has signed a memorandum of understanding (MoU) with US-based Nuvation Energy to explore the localisation and large-scale manufacturing of high-voltage battery management systems (BMS) in India. The agreement was signed during the 12th India Energy Storage Week 2026 in New Delhi.
The collaboration will initially focus on battery management systems for grid-scale energy storage, commercial and industrial (C&I) applications, and renewable energy integration. The companies aim to combine Nuvation Energy's high-voltage BMS technology with Amara Raja's manufacturing capabilities to develop products suited to the Indian market.
Battery management systems play a critical role in monitoring and protecting lithium-ion battery packs, ensuring safe operation, improving performance and extending battery life in large-scale energy storage installations. The companies said the partnership is intended to strengthen domestic capabilities in this segment as demand for energy storage rises alongside renewable energy deployment.
The announcement comes as India targets 500 GW of non-fossil fuel power capacity by 2030, a goal expected to require significant deployment of grid-scale battery storage to support renewable energy integration.
Amara Raja is expanding its lithium-ion manufacturing footprint through its ₹9,500 crore, 16 GWh gigafactory in Telangana, supported by research and development activities at ePositive Energy Labs. The company is also developing a 10 GWh battery energy storage system (BESS) manufacturing facility, which is expected to become operational later this year, according to the company.
Focus on Localising High-Voltage BMS
Nuvation Energy develops battery management systems for applications including grid-scale energy storage, commercial and industrial systems, aerospace, marine and defence. Its portfolio includes BMS platforms capable of supporting systems operating at up to 1,500V DC. Under the partnership, the companies will evaluate opportunities to manufacture these systems locally for the Indian market.
"The partnership gives us access to proven, globally validated technology that we aim to localise and scale for Indian conditions, supporting the country's clean energy transition," said Dr Vikash Venkataramana, Chief Product Officer, Amara Raja Advanced Cell Technologies.
