b. Current limiting: Sometimes the BMS will limit the flow of current so that it is within safe limits. You can achieve this by actively modifying the charging or discharging current of the battery to guarantee it stays below a predetermined threshold.
a. Current disconnect: One of the most common responses to an overcurrent is to disconnect the battery charging or discharging circuits. The BMS can quickly stop the flow of current by disconnecting the associated relay or transistor.
Here is how the battery protection board works for overcurrent protection: 1. Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit.

Continuous standard current sounds like "nominal" drain current, what current does the manufacturer expect to be a typical load under ordinary usage, probably much less than the maximum. In general you might expect this number to be something like 1/5 or 1/10 of the C rate, meaning a 5 hour or 10 hour time to fully discharge.
When the current in the protected circuit exceeds the preset threshold, the protective device intervenes actively, employing timing mechanisms to ensure the selectiveness of its response. This can result in either the circuit breaker tripping or the transmission of an alarm signal.
