Contact UsAccording to the previous analysis, because all lithium-ion batteries in the same battery pack operate under the same conditions, the state parameters of each battery, such as voltage, should exhibit similar trends. In other words, the Manhattan distance between the normal cells should be exceedingly small.
The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.
Overvoltage is when the charging voltage of the lithium-ion battery cell is increased beyond the predetermined upper limit, typically 4.2 V. The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure.
Low temperature also causes lithium plating due to non-uniformities occurring within the cell elements originating from the manufacturing defects or misuse of the cell. Over-discharge is when voltage is drained from the battery cell to below two volts.
Sidhu et al.31 employed the equivalent circuit and impedance spectrum methods of lithium-ion batteries to construct multiple nonlinear characteristic fault models characterizing battery overcharging, discharging, and other anomalies.
Fault over a short time horizon based on voltage difference and monomer voltage are diagnosed. Cell voltage inconsistency of a battery pack is the main problem of the Electric Vehicle (EV) battery system, which will affect the performance of the battery and the safe operation of electric vehicles.
