6 FAQs about [Conversion device battery undervoltage overcurrent protection]
Why is undervoltage protection important for lithium ion batteries?
To safely operate such a battery, the discharge current rate and battery voltage level must be monitored. Undervoltage protection is crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard.
Does a 48 volt battery have undervoltage protection?
In addition to undervoltage protection, it is important to ensure that the battery is discharging a safe current value. Combining undervoltage protection and overcurrent protection will ensure safe operation of the 48-V battery. For this design, a 48-V, 20-Ah lithium-ion battery was selected.
What is the difference between undervoltage protection and adjustable hysteresis?
Undervoltage protection cuts off low voltage batteries to prevent deep discharge, while adjustable hysteresis avoids oscillations from battery recovery after load removal. Input overvoltage disconnects the load, preventing damage.
What happens if a battery reduces OCV and R_Batt?
IMPORTANT: The reduction of OCV and/or the increase of R_batt cause the reduction of the fault current provided by the battery. Example: For the VRLA type battery close to the End of Discharge (EOD) and End of Life (EOL), due the OCV reduction and resistance increase, the short circuit current can be around 60% of the nominal short circuit current.
Does undervoltage protection require firmware control?
Thus undervoltage protection is often only included in the primary layer of protection, but not the secondary layer. Since modern primary protection ICs are designed to be as flexible and fully-featured as possible, finding a simple, inexpensive undervoltage protection solution that doesn’t require firmware control is not as easy as it should be.
Is undervoltage a critical fault condition?
Because undervoltage is not the most critical fault condition that needs to be detected (compared to overvoltage, overcurrent, and over temperature), it is generally difficult to find a simple device that implements undervoltage protection for each cell individually and does not include a host of unnecessary functionality.
