The Tata Group announces that AESC Group Ltd., a Yokohama-based battery manufacturer owned by Chinese energy technology giant Envision, has acquired a 12% stake in its EV battery subsidiary, Agratas Energy Storage Solutions Pvt. Ltd. The transaction, completed in March 2025, is valued at approximately ₹66 crore. This strategic investment marks a significant step in advancing Agratas’s capabilities in electric vehicle battery manufacturing.
This is the first official confirmation of the foreign or rather the China-related investment in one of the Tata Group rising ventures. Agratas, the group, originated in 2023 and is the main battery manufacturing asset of EV in India itself as well.
In the course of investment, Gordon Louis Chin, General Counsel of AESC Group has become an Agratas board of directors member, indicating that an enhanced strategic and operation partnership is established between the two companies.
Prior to the transaction, Tata Sons held 88 percent of Agratas with having invested 484 crore rupees since the time when it was started. The capital injection by AESC should help in fast-tracking consolidation of Agratas plans to set up a battery manufacturer to supply both local and overseas customers such as BMW, Mercedes-Benz, Renault-Nissan, and Honda.
Industry watchers view the investment as a strategic move that will benefit Agratas in terms of access to the latest battery technologies and strengthened links with world automakers in the electric mobility space. The joint venture underlines the growing relevance of the cross border cooperation in establishing India as an EV supply chain.
