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.
Lithium-Ion Battery Discharge. Discharging a lithium-ion battery is the process of releasing the battery''s stored electrical energy to power a device or perform other functions. The type and size of the battery, the age of the battery, and the temperature are all factors that can influence the discharging process.
Battery capacity refers to the amount of electricity released by the battery under a certain discharge system (under a certain discharge current I, discharge temperature T, discharge cut-off voltage V), indicating the ability of the battery to store energy in Ah or C. Capacity is affected by many elements, such as discharge current, discharge
A lithium-ion battery is one type of battery. Lithium-ion batteries are powered by the movement of lithium ions between electrodes.

When discharging a lithium-ion battery, the discharging current, or the amount of electrical energy drawn from the battery, is an important factor to consider. Higher discharging current results in a faster discharge time, but it can also cause battery damage and shorten its lifespan.
The charging and discharging of lithium ion battery is actually the reciprocating motion process of lithium ions and electrons. When charging, apply power to the battery to let lithium ions and electrons go to the graphite layer along different paths. At this time, lithium atoms It is very unstable.
It's worth noting that lithium-ion batteries can only be discharged so far before they need to be recharged. If a lithium-ion battery is discharged too far, it can be damaged and lose its ability to hold a charge. To ensure that the battery is charged safely and efficiently, it is also critical to use the proper charging methods and devices.
The primary reason for self-discharge in lithium-ion batteries is because their electrolyte comprises organic compounds that tend to break down over time, regardless of whether the battery is fully charged or in the charging process.
When in charging, li+ is deinterleaved from the anode and embedded in the cathode through the electrolyte, and the cathode is in a lithium-rich state. The opposite is true when discharging. Portable devices like mobile phones and laptops use lithium-ion batteries, especially lifepo4 batteries.
The discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan.
