LG Energy Solution's new advanced BMS software is available on Qualcomm's Snapdragon® Digital Chassis™. It is also planned to be integrated into the Snapdragon® Car-to-Cloud Connected Services Platform, allowing automotive manufacturers to utilize the diagnostic solution for human-machine interfaces (HMI) and cloud services.

Earlier this year, LG Energy Solution announced a collaboration plan with Qualcomm for the development of a next-generation BMS diagnostic solution to be installed in electric vehicles and has been conducting relevant research through a technical committee. An official from LG Energy Solution noted, "The excellence of our BMS technology and the synergy from our collaboration with Qualcomm have been proven through the technology sharing and verification processes, and we have decided to proceed with formal commercialization this time."

The BMS jointly developed by the two companies utilizes high-performance SoC computing capabilities, unlike the existing BMS that operated on low-spec hardware. This is a first in the industry. By using this method, it is possible to collect more data compared to the existing BMS, allowing for faster and more accurate diagnostics of abnormal signs, such as the possibility of fire.

The degradation diagnostic function is expected to become more sophisticated with over 80 times enhanced computing capabilities. This is due to the application of algorithms that could not be implemented in the existing BMS, which was only capable of simple computation. New functions will include the ability to predict remaining battery capacity after a certain period and to check the degradation performance indicators of the battery's detailed components, including anodes and cathodes.

This advanced BMS diagnostic software can operate in real-time without a separate server connection, allowing for the analysis and diagnostics of vehicle data, such as driving information, to be conducted autonomously within the vehicle.

Kim Dong-myung, president of LG Energy Solution, said, "It is significant to have opened the market for the industry's first SoC-based BMS in collaboration with semiconductor leader Qualcomm for the key future electric vehicle era, and soon many electric vehicles will provide differentiated customer value."
