State of Charge (SOC) Estimation
Accurate SOC estimation is crucial for maximizing range and optimizing charging. This review highlights the dominance of deep neural networks (CNN, LSTM, GRU) and hybrid models integrating Kalman filters or circuit models. Meta-heuristics like Genetic Algorithms and PSO are frequently used for parameter optimization.
Key findings indicate RMSE values as low as 0.02% for DCRNN models and MAE around 0.02% for LSTMNNGA. Hybrid approaches combining Kalman filters with deep networks consistently reduce RMSE to 0.04%. Digital twins and IoT-telemetry-driven approaches further enhance accuracy and robustness by continuously updating models with operational data, achieving performance improvements up to 18.6% in efficiency.
Enterprise Application: Deploying these advanced SOC estimation models enables fleets to optimize vehicle dispatch, manage charging loads effectively in V2G scenarios, and integrate with renewable energy sources, ultimately reducing operational costs and maximizing asset utilization.
State of Health (SOH) Estimation
SOH prediction is vital for predictive maintenance, warranty management, and second-life applications. The research shows a strong trend towards deep learning models such as CNN-LSTM, BiGRU, and GANs with attention mechanisms. Feature selection using methods like SVM-RFE and quantum Boltzmann machines is critical for improving accuracy.
Errors for SOH estimation are as low as RMSE ≈ 0.02% and MAPE ≈ 0.32% using DCRNN with SVM-RFE. Federated learning frameworks, which protect data privacy while leveraging fleet-wide insights, have shown SOH accuracy improvements of up to 20.18%. Physics-informed neural networks and models combining ECM with LSTM also prove more accurate and robust in capturing degradation patterns.
Enterprise Application: Implementing advanced SOH analytics allows for precise remaining useful life (RUL) prediction, enabling proactive battery replacement, efficient second-life repurposing, and robust anomaly detection to prevent failures and enhance safety across an entire vehicle fleet.
Thermal Management
Effective thermal management extends battery life, improves safety, and enhances performance. Research in this area combines CFD simulations with neural networks (ANN, Quantile CNN/RNN) and leverages deep reinforcement learning (RL) for dynamic control strategies.
CFD coupled with ANN models predict maximum cell temperatures with MSE ≈ 0.00552 and R² ≈ 0.99. Quantile CNN/RNN models achieve RMSE of about 0.66 °C for temperature prediction. Deep RL significantly reduces computation time for optimal charging and cooling (from >80 min to <1 sec), leading to core temperatures maintained below 33 °C and extending battery life by up to two years over 1000 fast charging cycles.
Enterprise Application: Optimizing thermal management through AI ensures safer battery operation, enables faster charging profiles without compromising cell integrity, and significantly extends the operational lifespan of EV batteries, translating to lower total cost of ownership for fleet operators.
Enterprise Process Flow: Data-Driven BMS
Leading models like Diffusion Convolutional Recurrent Neural Networks (DCRNN) with SVM-RFE feature selection achieved remarkably low estimation errors for State of Health, enabling ultra-high-precision battery state tracking critical for safety and performance.

Case Study: Deep Reinforcement Learning for Thermal Management
Challenge: Optimizing fast charging while preventing battery overheating and degradation is a complex problem, traditionally requiring lengthy computations (e.g., >80 minutes for Model Predictive Control).
Solution: Study [97] demonstrated the application of Deep Reinforcement Learning (DRL) for simultaneous optimization of charging current and coolant flow for a 20-cell battery pack. The DRL agent learned optimal strategies in less than one second, dramatically outperforming conventional methods.
Impact: This breakthrough led to the core battery temperature being maintained below 33°C (compared to 40°C with predictive control) and extended the battery's expected lifetime by up to two years over 1000 fast charging cycles. This revolutionizes the efficiency and safety of high-power EV charging.
