Safety Diagnostics

In the BMS there are a number of limits used to ensure the safe operation of the battery pack, including: voltage limits, temperature limits, current limits and minimum SoH for safe operation.

There are also a number of measurements used for safety diagnostics at cell level, including:

We have described these as part of the Battery Management System (BMS), but they are used in cell testing and end of the cell manufacturing line to determine cell faults and quality.

LGES safety diagnostics

LGES [1] describe a few of the safety diagnostics that they use to enable safe operation of the battery pack.

There are a number of safety diagnostics applied at pack level, including:
