Nuvation Energy’s High-Voltage BMS provides cell- and stack-level control for battery stacks up to 1500 V DC. One Stack Switchgear unit manages each stack and connects it to the DC bus of the energy storage system.
In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions. At present, model-based fault diagnosis methods are still the hot spot of research.
The Nuvation Energy High-Voltage BMS is a utility-grade battery management system for commercial, industrial and grid-attached energy storage systems.
Nevertheless, these devices may occur safety issues that can cause the battery system to fault or even lead to battery thermal runaway (BTR). The faults of the battery system cause significant damage to people's life and property safety. Meanwhile, it also increases people's safety anxiety about EVs [5, 6].
Common battery thermal management systems on real-world EVs mainly include water cooling and air cooling , as shown in Fig. 8. Among battery thermal faults, the most common fault is excessive temperature, which can cause significant damage to the battery unit and the entire system.
While BMS are designed to prevent over-charging by monitoring the SOC, factors like different charging modes (e.g., fast charging) and charging rates can lead to over-charge [69, 70]. Additionally, BMS misjudgment due to sensor faults can cause prolonged over-charging. The design and quality of battery cells also play a role.
