Free QuoteTo 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.
When the undervoltage protection kicks in, the battery gets disconnected and stops supplying power to the boost converter. This causes the battery voltage to rise slightly and the undervoltage circuit will no longer detect an udervoltage and it reconnects the battery again which causes its voltage to drop and the circuit to cutoff power.
Figure 1 shows an ultralow power, precision undervoltage-lockout circuit. The circuit monitors the voltage of a Li-Ion battery and disconnects the load to protect the battery from deep discharge when the battery voltage drops below the lockout threshold.
Undervoltage protection with comparator circuit (Rev. A) This undervoltage, protection circuit uses one comparator with a precision, integrated reference to create an alert signal at the comparator output (OUT) if the battery voltage sags below 2.0V. The undervoltage alert in this implementation is ACTIVE LOW.
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.
That is why we design our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries, so you can enhance the safety of your battery pack.
