How do you determine fault occurrence in a battery pack?
Lin et al. used the variation in the voltage difference between different cells (d Δ U) as a fault index and calculated the correlation coefficients between different cell voltages and d Δ U s for battery pack consistency analysis to determine fault occurrence.
What is a battery connection fault?
The resultant abnormality in the intercell contact resistance is defined as battery connection fault , . Such a type of fault can cause an uneven current flow into a cell, leading to a severe cell imbalance in a battery pack and an increase in heat generation . 4.1.3. SC faults
How can a fault be incorporated into a battery state?
To cope with restrictions, the fault can be incorporated into a battery state (e.g., short circuit (SC) current, sensor fault) as U 1, S O C, f T , . The fault severity can be directly estimated from the battery state, which leads to the improvement in fault response time and fault estimation accuracy.
