MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202617086249 A) filed by Avl List Gmbh on July 14, 2026, for On-Board System For A Vehicle And Method For Evaluating The Soh Of A High-Voltage Battery.
Inventors include Pallewar, Pankaj Ganeshrao; Kaneko, Kazumi; Sivaraman, Thyagesh; and Charkhgard, Mohammad.
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: The invention relates to an on-board system (100) and a method for evaluating the state of health (SOH) of a high-voltage battery (30) having a plurality of battery cells (31). Functional modules of the on-board system and method steps relate to the processes of: setting (11, S11) a discharge pulse via a measuring resistor (22) and a semiconductor switch (21); measuring (12, S12) cell voltages of individual battery cells (31) at a specified frequency; determining (13, S13) voltage differences between minimum cell voltages and maximum cell voltages; determining (14, S14) the internal resistance of the high-voltage battery (30); and determining (15, S15) the SoH on the basis of a characteristic diagram.
