Introduction
Electric vehicles (EVs) are central to global sustainability and decarbonization strategies. Yet, EV batteries remain a critical challenge: they are expensive, degrade over time, and can make or break the economics of electric mobility. Battery packs account for a major share of EV costs, and their performance directly influences customer adoption and fleet economics.
Predictive battery management systems (BDMS) offer a solution. By combining real-time monitoring, AI-powered analytics, and preventive alerts, these systems can extend battery lifespan, improve safety, and reduce total cost of ownership.
The Battery Cost & Degradation Challenge
- According to Goldman Sachs Research, average global EV battery prices declined from $153/kWh in 2022 to $149/kWh in 2023 and are expected to fall to $80/kWh by 2026. Falling costs make EVs more competitive, but only if batteries remain healthy and reliable.

Battery degradation results from factors like deep discharge, frequent fast charging, and overheating. Left unmanaged, this leads to range loss, reduced performance, and premature replacement.
Predictive Battery Management
Predictive battery management combines data capture (voltage, current, SoC, SoH, temperature) with AI/ML models to forecast degradation or failure. Unlike scheduled preventive maintenance, predictive systems dynamically adapt to actual conditions.
Key benefits include:
- Early detection of anomalies such as thermal issues or voltage imbalance.
- Optimized charging and discharging cycles.
- Reduction of unplanned downtime and costly failures.
- Longer battery lifespan and better warranty compliance.
Evidence & Statistics
- Deloitte notes that poor maintenance strategies can cut an asset’s productive capacity by 5–20%.
