Xbattery makes the circuit board that decides whether a battery pack works or burns

Xbattery Energy, an Indian startup founded in August 2024, has developed a battery management system (BMS) that plays a crucial role in determining the safety and longevity of battery packs. The company, which operates from T-Hub, Hyderabad's innovation hub, aims to produce these systems domestically, reducing dependence on foreign suppliers.

The BMS, known as BharatBMS, is a universal high-voltage system designed to cater to a wide range of applications. It is available in three versions - 51.2V, 72V, and 110V - with configurations suitable for home installations and industrial storage systems ranging from 5 kWh to megawatt-scale storage. The system manages heat, monitors cells in real time, balances charge distribution among cells, and enforces safety cut-offs to prevent overheating or fire hazards.

Xbattery's approach addresses the limitations faced by Indian battery pack assemblers who rely on foreign BMS manufacturers for their products. By producing the BMS in-house, Xbattery Energy eliminates the need for foreign suppliers, allowing for firmware customization and faster response times to issues. The company claims that its BMS can extend battery life by up to 15%, making it an essential component in ensuring the reliability and efficiency of battery-powered systems.

The BharatBMS is priced between ₹2,000 and ₹25,000 depending on the configuration, with lower prices for smaller applications like scooters and higher prices for applications in trucks and larger vehicles. The company emphasizes that all aspects of the BMS development, including design, firmware, thermal analysis, testing, programming, and assembly, take place at its Hyderabad facility, requiring specialized equipment such as thermal chambers, battery welders, electronic loads, and programmable chargers.
