LG Energy Solution said Monday (local time) that its used-battery diagnostic solution Re.Pulse has won a CES 2027 Innovation Award. The Consumer Technology Association, which administers the awards, recognized Re.Pulse in the advanced mobility category.

Re.Pulse is a software-based solution that quickly and precisely assesses a battery's state of health and remaining performance. It applies specific current pulses to a battery, measures the resulting voltage changes, and analyzes the data using a proprietary AI model to evaluate the battery's condition. Based on the diagnostic results, the solution determines whether a used battery is best suited for reuse, remanufacturing or recycling, helping maximize its residual value.

The most significant improvement is speed. Conventional methods require removing the battery pack and running a full discharge, charge and re-discharge cycle, a process that takes more than seven hours. Re.Pulse diagnoses battery condition in under 10 minutes without any of those steps.

Diagnostic precision has also improved. Previous approaches could only assess the average condition of an entire battery pack. Re.Pulse diagnoses at the individual cell level within the pack, identifying specific cell groups with degraded performance so that only the affected components need to be repaired or replaced. The company said this reduces premature disposal of entire battery packs, improves resource efficiency and cuts carbon emissions associated with producing replacement batteries.

The solution is also straightforward to deploy. It requires no dedicated diagnostic hardware and can be integrated with existing battery charge-discharge testers or EV chargers, and batteries do not need to be removed from the vehicle for diagnosis. Potential applications include used-battery ESS operations, EV maintenance and inspection centers, and fleet operators. LG Energy Solution plans to expand the service so that diagnostic results can also be accessed through web and mobile apps.

The award marks the second consecutive year LG Energy Solution has won a CES Innovation Award for a purely software-based technology, following last year's recognition of Better.Re, a battery-life enhancement solution. The company said the win reaffirms its software capabilities as it works to expand into an energy platform business.

"This CES Innovation Award reflects recognition of the distinctiveness of our battery diagnostic technology and our software competitiveness," said Lee Sang-hoon, head of Pack/BMS development and service solutions at LG Energy Solution. "We will continue to advance our diagnostic and management technologies to enhance the value of used batteries and build a sustainable battery circular ecosystem."

Meanwhile, LG Energy Solution is advancing lifecycle management technologies that span battery diagnostics, management and second-life applications. The company is also strengthening its Battery-as-a-Service capabilities as it moves beyond conventional battery manufacturing to broaden its presence as an energy platform company.
