In this study, a battery model for a single cell is established by coupling a single particle model with electrolyte, degradation model, and thermal model.
Abstract: Effective fast charging is of great importance in the application of lithium-ion battery packs. In this article, a combined battery pack charging system is constructed by integrating the charger and cell-to-cell equalizers, which can excellently solve the cell imbalance problem in the battery pack.
The continuous system limit of the electric vehicle battery pack is 250A. Hence, the maximum charging current of the pouch cell is set to 5C. Finally, the charging current of an unaged cell which is transmitted back to the test bench software and is set by the test bench hardware is given by: (3) I ch, k + 1 = min C rate, k + 1, 5 C ⋅ C nom
The maximum voltage of the battery pack is 403V and it has a nominal energy content of 17.6 kWh. The testing was done in a battery safety environment because the charging currents exceed the qualified currents of the cell manufacturer. The test bench system used was a Digatron EVT 300–450 (0–450V, ±300A).
Using a certified charger to charge lithium battery packs must be considered. Regulatory agencies have tested and approved certified chargers to meet safety standards and specifications, reducing the risk of potential hazards such as short circuits or overheating during the charging process.
It is recommended that lithium battery packs be charged at well-ventilated room temperature or according to the manufacturer’s recommendations. Avoid exposing the battery to extreme temperatures when charging, as this can affect its performance and life.
In their study, following a multi-module charger, a user-involved methodology with the leader-followers structure is developed to control the charging of a series-connected lithium-ion battery pack. In other words, they are exploiting a nominal model of battery cells.
Charging strategies based on the models can be adopted to prevent side reactions that may lead to severe degradation or even thermal runaway under various ambient temperatures. In this study, a battery model for a single cell is established by coupling a single particle model with electrolyte, degradation model, and thermal model.
Obviously, under the circumstance that there is no equalization system, the cell inconsistences will be further amplified with battery pack continuously charging, where the maximum voltage difference and maximum SOC difference among all in-pack cells at the end of CC charging stage is 0.1619V and 0.1650, respectively. By contrast, with all fully-charged in …
