Should used electric vehicle batteries be priced based on their historical usage data?
Quantum Hi-Tech has developed an AI-based system to assess electric vehicle battery health using data collected from 700 vehicles. This technology offers a faster alternative to traditional inspection methods for used electric vehicles.
Why it matters
Current market pricing for used electric vehicles often fails to accurately reflect long-term battery usage, which can affect resale values. This technology aims to shorten inspection times significantly, potentially providing more transparent battery health data.
Traditional battery inspections can take up to 65 hours to complete. Meanwhile, Quantum Hi-Tech reported 120 million Korean won in license sales during the first half of 2026.
The players
Quantum Hi-Tech
A developer of AI-based diagnostic technologies for automotive energy storage systems.
SMEC
An engineering and manufacturing firm partnering with Quantum Hi-Tech to develop battery inspection systems.
The details
The diagnostic system connects a terminal to an electric vehicle to collect voltage, current, and temperature changes at one-second intervals. Artificial intelligence then analyzes this data, which accumulates at a rate of 4GB per vehicle annually, to estimate degradation rates and remaining lifespan. By identifying these metrics without requiring battery removal, the system provides a more efficient snapshot of vehicle health.
Timeline
Data was collected from 700 vehicles between 2024 and 2026.
The company earned 120 million Korean won in license sales in the first half of 2026.
Quantum Hi-Tech plans to increase data collection to 2,000 vehicles by the end of 2026.
The company expects to expand revenue through subscriptions and APIs in 2027.
A break-even point is targeted for 2028.
The Home Front
The introduction of rapid battery diagnostics could eventually standardize how used electric vehicles are valued on the resale market. This development marks a departure from traditional, labor-intensive battery testing that currently dominates automotive maintenance.
Owners of electric vehicles should keep an eye on how battery health certifications might be integrated into future resale or trade-in documentation. For now, monitor the manufacturer's official software update notifications, as these may soon include better self-reporting tools for battery life.
The takeaway
AI-driven diagnostics may soon make the state of your electric vehicle's battery a transparent part of the resale process. Keep your service records organized, as they currently remain the best evidence of your battery's maintenance history.
