Amara Raja partners with Nuvation Energy to localize high-voltage battery management system technology in India

Amara Raja Advanced Cell Technologies (ARACT), an arm of Amara Raja Energy & Mobility Ltd (ARE&M), has partnered with Nuvation Energy, a global provider of advanced battery management systems (BMS), to jointly explore the localization and large-scale manufacturing of high-voltage BMS platforms in India.

The companies signed a memorandum of understanding (MoU) at the 12th India Energy Storage Week (IESW) 2026 in New Delhi. The collaboration will initially focus on grid-scale storage, commercial and industrial (C&I) systems, and renewable energy integration.

Amara Raja, India’s largest lead-acid battery manufacturer, is expanding lithium-ion battery capabilities through its INR 9,500 crore, 16 GWh Gigafactory in Telangana, backed by in-house R&D at ePositive Energy Labs, and a Customer Qualification Plant that is ready for cell production very soon. Meanwhile, work is advancing on a 10 GWh BESS facility that is expected to be operational later this year.

“Battery management systems are among the most technologically demanding components in the energy storage value chain, especially as grid-scale storage systems are growing in size and complexity,” said Vikash Venkataramana, Chief Product Officer, ARACT. “Our partnership with Nuvation Energy gives us access to proven, globally validated technology that we aim to localize and scale for Indian conditions, supporting the country’s clean energy transition.”

“India is at the center of one of the world’s most important energy storage stories, and getting the foundations right, starting with the battery management system, is essential to building a safe, reliable storage ecosystem at scale,” said Vikash Venkataramana, Chief Product Officer, ARACT. “Partnering with Amara Raja allows us to bring 15 years of high-voltage BMS engineering directly into India, alongside a manufacturing partner with the scale and quality discipline to help the country build a truly indigenous storage supply chain.”
