LG Energy Solution has developed a diagnostic system capable of assessing an electric vehicle battery’s condition in under 10 minutes, potentially making battery health checks more practical for used-EV buyers, workshops and fleet operators.
Called Re.Pulse, the software uses brief electrical current pulses to examine how a battery responds, rather than relying on a lengthy charging and discharging procedure.
The South Korean battery manufacturer claims its system can estimate battery state of health (SoH) in less than 10 minutes, against more than seven hours for a conventional full discharge-recharge-discharge capacity test.
SoH indicates how much of a battery’s original capacity remains as it ages, providing useful information about deterioration and potential remaining service life.
Re.Pulse also examines degradation at cell-bank level instead of relying solely on an assessment of the entire battery pack.
According to LG, this could help identify deteriorated sections while distinguishing them from cells that remain usable, potentially reducing unnecessary replacement or disposal of complete battery packs.
The software is designed to work with compatible conventional battery capacity testers and EV chargers without requiring dedicated diagnostic hardware.
That could allow battery assessments to be carried out at maintenance centres, fleet facilities and used-vehicle evaluation sites, subject to equipment compatibility.
Beyond vehicle inspections, LG intends to use the diagnostic information to determine whether ageing batteries are suitable for reuse, remanufacturing or recycling.
Re.Pulse was named a 2027 CES Innovation Awards honoree in the Vehicle Tech & Advanced Mobility category, recognising its approach to battery lifecycle management.
However, the award does not constitute independent verification of LG’s performance claims.
The company has not published independent accuracy or repeatability results in its announcement, leaving the diagnostic system’s performance across different battery chemistries and ageing conditions unestablished.
