LG Energy Solution launches five-minute EV battery health tool

LG Energy Solution (LGES) has launched B.once, a new diagnostic tool designed to assess the health of electric vehicle (EV) batteries quickly and accurately. The service offers two diagnostic modes: Quick Scan, which delivers battery health results in five minutes by analyzing capacity, voltage, and temperature through an onboard device, and Power Scan, which provides a more detailed report within 30 minutes by examining charging data between 50% and 80% state of charge. B.once aims to increase transparency in the used EV market by enabling dealerships and resale platforms to issue reliable battery assessment reports, helping buyers better understand vehicle conditions. The tool is supported by LGES’s extensive battery management expertise and over 10,000 global patents, with early adoption by used EV platform Revolt. This launch is part of LGES’s broader strategy to expand its Battery as a Service (BaaS) offerings, complementing existing services like B.Lifecare, which provides regular battery diagnostics for EV owners.
