LG Energy Solution said it will offer Battery Management System (BMS) solutions to its electric vehicle (EV) clients.
LG Energy Solution’s safety diagnostics software analyzes battery defects including voltage drop during charging, battery tab failure, micro internal short circuit, abnormal degradation, abnormal discharge, deviation in specific cell capacity, and excessive lithium precipitation.
Safety diagnostics software detects battery defects with an accuracy rate of over 90 percent, says LG Energy Solution.
LG Energy Solution has over 8,000 BMS-related patents. The company has developed a safety diagnostics software based on empirical data obtained by disassembling and analyzing more than 130,000 battery cells and 1,000 battery modules.
LG Energy Solution has already applied software to more than 100,000 EVs, recording a detection accuracy rate of more than 90 percent.
LG Energy Solution’s safety diagnostics software, which will be mounted on the automotive BMS, will provide functions that preemptively diagnose various battery abnormalities. In fact, it is already being applied to vehicles from nine global automakers.
“LG Energy Solution has already developed diagnostics software with capabilities that overwhelm the competition. Backed by various battery patents and vast amounts of empirical data, this leading vehicle software can be applied to an automotive BMS today,” said Hyuksung Chung, Vice President of the Business Development Group at LG Energy Solution.
In addition to a safety diagnosis function, LG Energy Solution has developed a technology that diagnoses and predicts battery degradation. Through this technology, the software can predict a battery’s future capacity and degradation based on data gathered on various information such as driving patterns.
In addition, LG Energy Solution is using cloud technology to analyze battery data in real time, with data from a total of 12,000 vehicles analyzed as of last year.
LG Energy Solution has been working to strengthen its BMS capabilities through collaborative efforts, including its cooperation with Qualcomm Technologies to develop advanced BMS diagnostic solutions based on SoC, and an MOU with Analog Devices (ADI), a global semiconductor leader, for the supply of battery management integrated circuit and joint technology development.
LG Energy Solution has posted KRW 6.1619 trillion in consolidated revenue and KRW 195.3 billion in operating profit in April-June 2024.
