LG Energy Solution has developed software that is said to assess the condition of used batteries in under 10 minutes. The tool, called Re.Pulse, was named an honoree of the CES Innovation Awards 2027 in the Vehicle Tech & Advanced Mobility category. The South Korean battery manufacturer announced the award on November 9. Based on the results, batteries can be routed to reuse, remanufacturing or recycling.
Current Pulses Instead of Full Cycles
Re.Pulse applies current pulses to a battery and analyzes the voltage response. According to The Elec, an AI model evaluates the data. Conventional state-of-health tests require a full discharge, recharge and second discharge, which LG Energy Solution says takes more than seven hours. The software evaluates each cell individually rather than only the pack as a whole. This is intended to identify degraded cells that can be repaired or replaced.
The tool requires no dedicated hardware and works with standard battery testers and EV chargers. It can also be used on batteries still installed in vehicles. LG Energy Solution has not disclosed the diagnostic accuracy, supported cell chemistries or a launch date. CES honorees are selected based on submitted materials, not independent tests.
Part of Battery-as-a-Service Plans
LG Energy Solution targets EV service centers, fleet operators, used-vehicle platforms and second-life storage projects. The company plans to integrate Re.Pulse into its battery-as-a-service business. It received a CES Innovation Award last year for B.artery, a technology designed to extend battery life.
