MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202647067518 A) filed by Lg Energy Solution, Ltd. on May 29, 2026, for Battery System And Method For Diagnosing Condition Of Link Capacitor According To Operation Of Precharge Circuit.
Inventor includes Kim, Sookwon.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The present invention relates to a battery system comprising: two terminals connected to an external device including a link capacitor connected in parallel to a battery pack; a precharge circuit connected between one end of the battery pack and one end of the link capacitor; a main relay connected in parallel to the precharge circuit; and a battery management system which controls a turn-on operation of a precharge relay and a main relay, calculates a reference power amount estimated to be supplied to a precharge resistor during a driving time of the precharge circuit, calculates a target power amount supplied to the precharge resistor during the driving time of the precharge circuit, and diagnoses a condition of the link capacitor as one of a plurality of failure states on the basis of a comparison result between a threshold power amount and the target power amount according to the reference power amount and a comparison result between a pack voltage of the battery pack and a link voltage between the two terminals.
