1. What is the difference between a BMS and a battery charger?
The BMS is responsible for monitoring and managing the safety and health of the battery pack, while the battery charger only provides charging current. The BMS ensures that the battery is not overcharged, over-discharged, and overheated through charge and discharge management.
-
2. What is battery balancing? How does BMS achieve it?
Battery balancing is to ensure that all batteries work in unison by balancing the voltage of each battery cell. The BMS gradually balances the battery during charging through passive or active balancing technology to prevent some cells from overcharging or discharging.
-
3. What are the typical applications of PMIC battery management systems?
BMS is widely used in scenarios such as electric vehicles, portable devices, industrial energy storage systems and medical equipment that require multi-battery unit management to ensure safety and stable performance.
-
4. How does the design of BMS consider different types of batteries?
Different types of batteries (such as lithium-ion, nickel-metal hydride, lead-acid, etc.) have different charging and discharging characteristics. BMS needs to adjust management parameters according to the battery type to ensure the best protection and management of the battery.
