LGES, Qualcomm to jointly develop battery management system

By Baek Byung-yeul, The Korea Times - LG Energy Solution joined hands with the U.S. chip company Qualcomm to develop software for an advanced battery management system (BMS) to optimally manage the performance and life span of batteries for electric vehicles (EVs), the battery arm of LG Group said Sunday.

The battery company said it will combine its BMS diagnostic software with some features of Qualcomm's Snapdragon Digital Chassis — a set of hardware and software solutions for connected vehicles — to develop an advanced BMS solution.

BMS is an essential system in EV batteries that utilizes battery data such as current, voltage and temperature to help the product perform optimally and detect and respond to problems in advance. The system is becoming increasingly important as more EVs hit the road.

The Snapdragon Digital Chassis is an integrated hardware and software platform that brings together smart features that can be applied across multiple vehicles.

The companies said the product made through their collaboration will provide more than 80 times the computing power to run more sophisticated battery diagnostic algorithms than traditional BMS software and will function without communicating with servers.

"This collaboration will enable the development of various solutions that are directly linked to the vehicle's driving information as well as real-time battery status diagnosis, creating a differentiated customer experience," an LG Energy Solution spokesperson said.

LG Energy Solution said the cooperation is based on its BMS data analysis technology.

Given most existing battery diagnostic algorithms were developed by predicting hypothetical conditions rather than data extracted from actual batteries, the battery company secured its own battery analysis algorithm technology based on the performance of more than 10,000 batteries.

"As the electric vehicle market grows, the importance of safe and healthy battery management is also growing," Chung Hyuk-sung, vice president of LG Energy Solution, said. "Through cooperation with Qualcomm, we expect to deliver differentiated customer value to our customers."
