The inconsistency of lithium-ion battery parameters mainly refers to the inconsistency of capacity, internal resistance, and open circuit voltage. Inconsistent battery cells used in series can cause the following problems.

1) Capacity loss refers to the formation of individual battery cells in a battery pack, which conforms to the principle of a wooden barrel. The capacity of the worst cell determines the overall capacity of the battery pack.

In order to prevent overcharging and discharging of the battery, the logic of the battery management system is set as follows: during discharge, when the lowest individual voltage reaches the discharge cut-off voltage, the entire battery pack stops discharging; When charging, stop charging when the highest individual voltage touches the charging cutoff voltage.

Take two batteries connected in series as an example. One battery has a capacity of C, while the other has a capacity of only 0.9C. Series connection, two batteries pass through the same amount of current.

When charging, a small capacity battery must be fully charged first, reaching the charging cutoff condition, and the system will no longer continue to charge. When discharging, a small capacity battery will inevitably release all available energy first, and the system will immediately stop discharging.
