System and method for preventing reuse of battery monitoring system

A method of preventing reuse of a battery monitoring system (BMS), the method comprising steps of:

• (a) monitoring specifications of a battery;
• (b) determining whether a cell has been replaced in a battery pack based on the step (a);
• and
• (c) determining whether to enter into a permanent failure mode based on the step (b).

An apparatus for preventing reuse of a battery monitoring system (BMS), the apparatus comprising:

• an input interface device configured to receive information on specifications of a battery, the specifications comprising a capacity of the battery or an internal resistance of the battery;
• a memory configured to store information related to a program determining whether a cell has been replaced by an unauthorized entity based on the information on the specifications of the battery;
• and
• a processor configured to execute the program,
• wherein the processor is configured to determine whether the cell has been replaced based on a maximum reference capacity, a reference capacity, a maximum reference resistance, or a reference resistance.
