SEOUL, South Korea,
Aug. 21, 2024 /PRNewswire/ -- LG
Energy Solution announced today that it is venturing into the
battery safety diagnostics software business. With interest in the
safety of EVs at an all-time high, the company has decided to
explore new business opportunities and provide the best customer
value not only in battery manufacturing but also in BMS (Battery
Management System) solutions, promoting the safe use of
batteries.
- Safety diagnostics software detects
battery defects with an accuracy rate of over 90%
LG Energy Solution boasts unrivaled technological leadership in
the battery safety diagnosis sector with its BMS design
capabilities and empirical battery data gathered over 20 years.
With 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. This reliable software has already been
applied to more than 100,000 EVs, recording an impressive detection
accuracy rate of more than 90%.
Based on its leading technological prowess, LG Energy Solution's
safety diagnostics software analyzes various 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.
Until now, most battery diagnostics software solutions were
based on technologies developed by predicting virtual conditions,
leading to low accuracy when applied in real environments.
- Software preemptively detects abnormal signs that could lead
to potential future issues
The growing interest in the safe use of EVs highlights the
importance of developing a sophisticated battery condition
management, prompting automakers to pay more attention to the BMS'
ability to effectively measure and analyze battery information and
detect various problems in advance.
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.
Based on a safety diagnosis detection accuracy rate of over 90%,
the software can detect and alert abnormal signs indicating
potential future issues, such as thermal incidents, in advance,
ensuring driver safety and peace of mind. In addition, LG Energy
Solution's software is receiving attention for its compatibility
with EVs equipped with batteries from other manufacturers.
LG Energy Solution has decided to expand its safety diagnostics
software business in collaboration with global automakers based on
its proven safety diagnosis accuracy and accumulated technological
prowess.
"Although automakers are starting to shift their attention to
safety diagnosis technology, it takes time and resources to develop
and apply reliable software," said Hyuksung Chung, Vice President
of the Business Development Group at LG Energy Solution. "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. This
move aligns with our commitment to actively collaborate with our
clients to ensure EV batteries are safe to use."
- Precise diagnosis and degradation prediction
with 1% range error rate
In addition to a safety diagnosis function, LG Energy Solution
has developed a technology that precisely 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. Based on LG Energy Solution's
expertise in battery electrochemistry, the software has applied a
battery physics model which includes various and complex
degradation mechanisms such as lithium precipitation and
degradation of cathode and anode.
The software also diagnoses battery conditions more accurately
by continuously upgrading its algorithms via AI computing
technology. By continuously applying and supplementing battery cell
information from various EVs to the algorithm, the error rate of
battery degradation diagnosis has been reduced to the 1% range,
top-level in the industry.
In addition, LG Energy Solution is using cloud technology to
analyze vast amounts of battery data in real time, with data from a
total of 12,000 vehicles analyzed as of last year.
Also, BMS software optimized for SDVs (Software Defined Vehicle)
is being developed to target the future mobility era, where
vehicles will become lifestyle platforms. By utilizing the
vehicle's SoC (System-on-Chip) computing performance, computational
capabilities can be enhanced and more sophisticated battery
algorithms can be implemented. This will also unlock new battery
services for customers by utilizing information obtained directly
from the vehicle.
LG Energy Solution has been working to strengthen its BMS
capabilities in recent years through various collaborative efforts,
including its cooperation with Qualcomm Technologies to develop
advanced BMS diagnostic solutions based on SoC, and an MOU with
Analog Devices, Inc. (ADI), a global semiconductor leader, for the
supply of high-performance battery management integrated circuit
and joint technology development.
"We will continue to provide irreplaceable and differentiated
customer value, not only in battery manufacturing but also in the
field of BMS solutions to ensure the highest levels of safety and
performance," said David Kim, CEO of
LG Energy Solution.
