B.once is a service that allows users to clearly assess the condition of a vehicle-installed battery-including remaining capacity, voltage, and temperature-with a single diagnosis in just five minutes.

Notably, B.once was developed based on LG Energy Solution's battery management system (BMS) design capabilities, which are backed by the world's largest portfolio of over 10,000 battery management and diagnostic patents, as well as the company's long-proven technological expertise through years of battery supply. Since 2009, LG Energy Solution has supplied more than 8 billion battery cells to approximately 15 million electric vehicles.

Vehicle dealerships can diagnose batteries using the diagnostic device and the dedicated B.once application provided by LG Energy Solution, thereby increasing transaction reliability with the issued battery evaluation report. Consumers can now purchase electric vehicles with greater safety and confidence.

B.once offers two diagnostic methods: 'Quick Scan' and 'Power Scan', depending on the approach to battery condition assessment. Quick Scan allows users to connect an onboard diagnostic device to the electric vehicle and assess the battery condition within five minutes after starting the engine. Power Scan is a more advanced service designed for areas requiring precise diagnostics, such as used car battery warranty products in partnership with insurance companies. Power Scan utilizes actual charging data from 50% to 80% state of charge to provide a more detailed analysis of the battery's condition, and can issue a battery evaluation report within 30 minutes after charging is complete. Compared to other companies, which require at least five days of driving data after charging, B.once enables faster and more accurate diagnostics.

The entire B.once diagnostic process can be monitored in real time via the dedicated app, and the evaluation results are provided in a report that is intuitively understandable, rather than simply presenting numerical data. This report is designed to make it easy to comprehend battery information (such as capacity, average energy efficiency, and cell deviation), driving prediction data, battery charging information, and degradation details.

Kim Hyunjun, Head of Battery-as-a-Service (BaaS) at LG Energy Solution, stated, "B.once is expected to invigorate the electric vehicle trading market by linking with new products in insurance and finance, and to contribute to the expansion of the electric vehicle ecosystem. Going forward, we will continue to enhance customer value in the BaaS sector with our unrivaled battery technology, while strengthening our competitiveness in the global market through overseas business expansion."
