What Is Charging Overcurrent Protection ?

Charging Overcurrent Protection in a lithium battery pack typically refers to the measures taken by the BMS to prevent damage to the battery pack when the charging current exceeds a set safety limit during the charging process. The main protection data includes:

Key Data for Charging Overcurrent Protection:

1. Overcurrent Threshold: The maximum safe charging current is set, and exceeding this value will trigger the protection. This threshold is typically determined by the battery's maximum charging current, which is generally specified by the battery's specifications and the manufacturer's recommended maximum charging rate.

2. Overcurrent Response Time: When the current exceeds the set threshold, the BMS needs to react within a certain time frame, either disconnecting the current or adjusting the       charging rate.

3. Duration of Overcurrent: If the charging current remains above the set threshold for a prolonged period, the BMS will trigger the protection mechanism. If the duration is too long, it may lead to battery overheating, aging, or safety issues.

4. Current Limiting Value: In some cases, the BMS will automatically adjust the charging current to ensure it stays below the safety limit, rather than completely disconnecting the charge.
