MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541134719 A) filed by Indian Institute Of Technology, Hyderabad, Telangana, on Dec. 31, 2025, for 'fault-responsive isolation and failover operation in a dual-battery electric vehicle.'
Inventor(s) include Ganta Bhanu Ganesh; and Pradeep Kumar Yemula.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a dual battery electric vehicle architecture including a permanently installed main battery and a removable add-on battery, and a control method for safely managing power delivery therefrom. A vehicle control unit selectively couples either the main battery or the add-on battery to a high-voltage power bus using independently controlled contactors. The system continuously monitors voltage, current, and temperature parameters to detect abnormal conditions including under-voltage, over-current, and internal short-circuit faults. Upon detection of a fault, the vehicle control unit executes a prioritized protection strategy including load reduction, electrical isolation of a faulted battery, controlled failover to a healthy battery, or safe vehicle shutdown. A mechanical presence detection element is used to distinguish physical removal of the add-on battery from electrical fault conditions and to enforce a removal interlock when required."
