About Does BMS need to control the battery charging current
There are many types of BMS (and many definitions of "normal"), but generally, in case of too high a charging current, a BMS will not limit the current to an acceptable level but simply stop the charging, and yes, this does protect the battery, but there will be no charging.

6 FAQs about [Does BMS need to control the battery charging current ]
What does a BMS battery charger control?
BMS battery chargers utilize complex algorithms to control BMS charge voltage, BMS charge current and BMS charge profile. These chargers are designed to work in coordination with the BMS charging circuit and the BMS charging pad to ensure safe and efficient charging.
What does the BMS do during charging?
During charging, the BMS ensures that the battery voltage and battery management charging current remain within safe limits to prevent overcharging. The BMS has the capability to monitor both charging and discharging processes concurrently.
Can a BMS charge a battery simultaneously?
Certainly, the BMS has the capability to control both the battery charger and the load concurrently. Components such as BMS charging circuits and BMS charging boards facilitate this coordination.
What is a battery management system (BMS)?
A battery management system (BMS) is a system that monitors both charging and discharging processes concurrently. It ensures that the battery voltage and charging current remain within safe limits during charging to prevent overcharging.
What does the BMS do to protect the battery?
The BMS can disconnect the current to protect the battery from damage. It uses mechanisms such as BMS charge voltage regulation and BMS charge current regulation to ensure the battery's safety. Although the BMS itself is not a charger, it plays a key role in monitoring cell status.
What parameters does a BMS adjust for charging lithium batteries?
The BMS communicates with the charge source to adjust parameters such as the BMS charge voltage and BMS charge current to ensure the charging protocol suitable for lithium-based batteries. While using a BMS to charge 18650 batteries is possible, it requires compatibility with accurate CC/CV profiles tailored for lithium batteries.
