LG Energy Solution announced on the 10th that its post-use battery condition diagnostic solution, "Re.Pulse," has won an Innovation Award at CES 2027, the world's largest consumer electronics and information technology (IT) exhibition.
Re.Pulse was selected as a winner in the Advanced Mobility category of the CES 2027 Innovation Awards, which are chosen by the U.S.-based Consumer Technology Association (CTA). It is a software-based solution that rapidly and precisely analyzes a battery's state of health and residual performance.
Its most notable feature is the reduction in diagnostic time. Previously, after removing the battery pack, it had to undergo full discharge, charging, and re-discharge cycles, taking more than seven hours for diagnosis. Re.Pulse shortens this to within 10 minutes by applying a specific current to the battery and analyzing voltage changes using an artificial intelligence (AI) model.
Diagnostic precision has also been improved. While conventional methods could only check the average condition of the entire battery pack, Re.Pulse can analyze the status down to individual cells within the pack. This allows for the identification of degraded cells so that only the necessary parts can be repaired or replaced. The company stated that this reduces the early disposal of entire batteries and improves resource utilization.
Another advantage is that no separate dedicated diagnostic equipment is required. It can be used in conjunction with existing battery charge/discharge testers or electric vehicle chargers. Since the condition can be checked without removing the battery from the vehicle, it can be utilized at EV maintenance and inspection centers as well as by vehicle operators.
Based on diagnostic results, it is also possible to determine whether post-use batteries should be reused, remanufactured, or recycled. Batteries in good condition can be reused in energy storage systems (ESS), while those with degraded performance can be repaired or recycled to enhance their residual value. LG Energy Solution plans to expand the service so that diagnostic results can be accessed via web and mobile apps in the future.
As the spread of electric vehicles is expected to increase the volume of post-use batteries, the importance of technology for rapidly and accurately assessing battery residual value is growing. In fact, following its battery life enhancement technology "Better.Re" last year, LG Energy Solution has won a CES Innovation Award for software technology for two consecutive years.
Lee Sang-hoon, head of pack and battery management system (BMS) development and service solutions at LG Energy Solution, said, "We will continue to advance our diagnostic and management technologies to enhance the utilization value of post-use batteries and work toward building a sustainable battery circular ecosystem."
