Data-Driven Fault Diagnosis of Lithium-Ion Battery Overdischarge in Electric Vehicles

Gan, Naifeng (author), Sun, S.Z. (author), Zhang, Zhaosheng (author), Xu, Shiqi (author), Liu, Peng (author), Qin, Z. (author)

The overdischarge can significantly degrade a lithium-ion (Li-ion) battery's lifetime. Therefore, it is important to detect the overdischarge and prevent severe damage of the Li-ion battery. Depending on the battery technology, there is a minimum voltage (cutoff voltage) that the battery is allowed to be discharged in common practice. Once the...

Python Supervised Co-simulation for A Day-long Harmonic Evaluation of EV Charging

Wang, L. (author), Qin, Z. (author), Beloqui Larumbe, L. (author), Bauer, P. (author)

To accurately simulate electric vehicle DC fast chargers' (DCFCs') harmonic emission, a small time step, i.e., typically smaller than 10 μs, is required owing to switching dynamics. However, in practice, harmonics should be continuously assessed with a long duration, e.g., a day. A trade-off between accuracy and time efficiency thus exists. To...
