Should used electric vehicle batteries be priced based on their historical usage data?
Quantum Hi-Tech has introduced an AI-based system designed to assess the state of health of electric vehicle batteries. The technology replaces traditional, lengthy inspection processes by analyzing battery voltage, current, and temperature changes.
Why it matters
Traditional inspection methods require removing batteries and can take up to 65 hours, often resulting in inaccurate pricing for used vehicles. This new technology offers a faster, more reliable way to assess battery degradation and remaining lifespan.
The system processes 4GB of battery data per vehicle annually to predict health status with an error rate of 3% using charging data and 5% using driving conditions. License sales reached 120 million Korean won in the first half of 2026.
The players
Quantum Hi-Tech
This technology company is developing artificial intelligence solutions specifically for the electric vehicle battery diagnostic market.
SMEC
This company is currently collaborating with Quantum Hi-Tech on the co-development of an advanced battery inspection system.
The details
The diagnostic process involves connecting a terminal to the vehicle to collect data at one-second intervals for AI analysis. This approach provides a clearer picture of battery condition compared to current methods that fail to capture long-term usage patterns in the used market.
Timeline
Data was collected from 700 vehicles between 2024 and 2026.
The company recorded 120 million won in license sales during the first half of 2026.
An additional 2,000 vehicles will be added to the data collection set by the end of 2026.
Recurring revenue through subscription and API models is set to launch in 2027.
Quantum Hi-Tech anticipates reaching a break-even point by 2028.
Roadmap
This innovation represents a shift toward software-defined battery management, replacing manual labor-intensive testing with automated AI diagnostic systems. Such advancements position Quantum Hi-Tech to compete in the growing global market for secondary electric vehicle battery certification.
For used electric vehicle owners and buyers, this technology could standardize battery valuation and reduce the uncertainty associated with degraded capacity. It aims to eliminate the lengthy inspection wait times currently required at professional service centers.
The takeaway
Automated battery diagnostics represent a necessary evolution to support the transparency of the growing used electric vehicle market. Buyers should look for certified battery health reports in the future to ensure they are paying a fair price based on actual remaining battery life.
What happens next
Quantum Hi-Tech is scheduled to expand its data collection to 2,000 additional vehicles by the end of 2026, followed by the introduction of subscription and API-based recurring revenue models in 2027.
