Special Issue Information

Dear Colleagues,

In recent years, we have witnessed phenomenal growth in electrochemical battery technologies driven by the proliferation of Li-ion batteries in the e-mobility and renewable energy storage sectors. At present, we are witnessing beyond-Li-ion breakthroughs in the form of new cell chemistries and configurations, as exemplified by the Na-ion chemistry and anode-free configurations. For all chemistries and configurations, it holds that the successful implementation in battery-powered systems is dependent on the design of the battery management system (BMS), since this finally determines the performance of the system in its broadest sense. The BMS is, therefore, the key enabling component to assure the dependability of emerging battery technologies.

For this Special Issue, we seek contributions focusing on challenges, solutions and improvements to the BMS hardware and software. We aim to highlight recent innovative discoveries addressing battery safety, state-of-charge (SoC), state-of-health (SoH), state-of-power (SoP) estimation, thermal behavior, thermal runaway prediction and Li plating. Moreover, we are happy to receive contributions on the implementation of advanced measurements techniques/diagnostics, sensors and reference electrodes for BMS.

Topics of interest include, but are not limited to:

  • State-of-charge (SoC) state-of-health (SoH) and state-of-power (SoP) estimation;
  • Models for BMS;
  • Battery diagnosis;
  • Battery aging;
  • Balancing techniques;
  • Reference electrodes and sensors for BMS;
  • Measurement techniques for BMS;
  • Advanced BMS safety features;
  • Thermal management systems;
  • Artificial Intelligence in BMS;
  • Cloud-connected BMS;
  • Beyond-Lithium BMS.

State-of-health (SoH) estimation is one of the key tasks of a battery management system, (BMS) as battery aging results in capacity- and power fade that must be accounted for by the BMS to ensure safe operation over the battery’s lifetime. In this study, an online SoH estimator approach for NMC Li-ion batteries is presented which is suitable for implementation in a BMS. It is based on an observer structure in which the difference between a calculated and expected open-circuit voltage (OCV) is used for online SoH estimation. The estimator is parameterized and evaluated using real measurement data. The data were recorded for more than two years on an electrified bus fleet of 10 buses operated in a mild European climate and used regularly in the urban transport sector. Each bus is equipped with four NMC Li-ion batteries. Every battery has an energy of 30.6 kWh. Additionally, two full-capacity checkup measurements were performed for one of the operated batteries: one directly after production and one after two years of operation. Initial validation results demonstrated a SoH estimation accuracy of ±0.5% compared to the last checkup measurement. Full article

Variations across cells, modules, packs, and vehicles can cause significant errors in the state estimation of LIBs using machine learning algorithms, especially when trained with small datasets. Training with large datasets that account for all variations is often impractical due to resource and time constraints at initial product release. To address this issue, we proposed a novel architecture that leverages electronic control units, edge computers, and the cloud to detect unrevealed variations and abnormal degradations in LIBs. The architecture comprised a generalized deep neural network (DNN) for generalizability, a personalized DNN for accuracy within a vehicle, and a detector. We emphasized that a generalized DNN trained with small datasets must show reasonable estimation accuracy during cross validation, which is critical for real applications before online training. We demonstrated the feasibility of the architecture by conducting experiments on 65 DNN models, where we found distinct hyperparameter configurations. The results showed that the personalized DNN achieves a root mean square error (RMSE) of 0.33%, while the generalized DNN achieves an RMSE of 4.6%. Finally, the Mahalanobis distance was used to consider the SOH differences between the generalized DNN and personalized DNN to detect abnormal degradations. Full article
