LG Energy Solution Collaborates with US ADI to Develop Real-Time Battery Internal Temperature Measurement Technology

LG Energy Solution Battery and BMS Technology Combined with ADI Impedance Measurement Technology
Individual Cell Temperature Estimation...Enhanced Safety and Improved Fast Charging Speed Possible

LG Energy Solution announced on the 5th that it is partnering with American semiconductor company Analog Devices (ADI) to strengthen electric vehicle battery management system (BMS) technology.

On the same day, the two companies signed a memorandum of understanding (MOU) at ADI's headquarters in Boston, Massachusetts, to jointly develop technology for measuring the internal temperature of electric vehicle battery cells. Over the next two years, they will supply high-performance battery management chips (BMIC) and collaborate on developing fast-charging technology through the establishment of precise battery temperature measurement algorithms. ADI has a diverse portfolio of BMICs.

One of the key technologies in this collaboration is the impedance measurement method, which measures resistance that obstructs the flow of current and voltage. This allows for precise analysis and diagnosis of the battery's internal condition. Previously, BMS attached temperature measurement devices to the outside of battery cells.

The two companies plan to develop technology that can measure the internal temperature of battery cells more accurately and in real time. This is expected to improve battery performance and lifespan by enhancing charging speed and fast-charging safety.

Until now, this technology has mainly been applied to analyze defects in used batteries. Many research institutions are studying the application of this technology to electric vehicle batteries in use, but it has not yet been commercialized.

Lee Dal-hoon, head of LG Energy Solution's BMS Development Center, said, "Through this collaboration, we will further enhance BMTS capabilities to strengthen LG Energy Solution's technological prowess and customer value." Roger Quinn, head of ADI's BMS division, stated, "We will work with LG Energy Solution to launch cutting-edge batteries to the market and advance a clean energy ecosystem."

Earlier, in March, LG Energy Solution began developing an advanced BMS diagnostic solution based on system-on-chip (SoC) technology in collaboration with Qualcomm. The partnership with ADI is part of LG Energy Solution's ongoing efforts to strengthen its battery management total solution (BMTS) capabilities.
