LG Energy Solution's AI cuts battery testing time to 10 minutes

LG Energy Solution said Monday its AI-powered battery diagnostic software, Re.Pulse, has won a CES 2027 Innovation Award for cutting the time needed to assess used batteries from more than seven hours to less than 10 minutes.

The technology, recognized in the Vehicle Tech & Advanced Mobility category, uses artificial intelligence to analyze changes in battery voltage in response to controlled electrical pulses, which can be used to assess battery health and remaining capacity.

The results help determine whether used batteries can be reused, remanufactured or recycled.

Conventional testing involves removing battery packs and repeatedly charging and discharging them, a process that takes more than seven hours. Re.Pulse can complete the assessment in under 10 minutes without those steps, according to the company.

Unlike conventional methods that measure the overall condition of an entire battery pack, the software can detect deterioration in individual cells. This allows operators to identify components that need repair or replacement rather than discarding the entire pack.

Re.Pulse also works with existing battery testing equipment and EV chargers, eliminating the need for dedicated hardware. It can assess batteries without removing them from vehicles, making it suitable for EV maintenance centers, fleet operators and energy storage facilities.

LG Energy Solution plans to make diagnostic results accessible through web and mobile platforms.

The award marks the company's second consecutive CES Innovation Award for software technology, following recognition of its Better.Re battery life extension solution last year.

"This award recognizes the competitiveness of our battery diagnostic technology and software capabilities," said Lee Sang-hoon, head of pack and battery management system development and service solutions at LG Energy Solution.

The company is expanding its Battery-as-a-Service business, which covers battery diagnostics, lifecycle management and services for batteries at the end of their useful life.
