6 FAQs about [Low voltage and high current protection battery]
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.
What is a battery protection circuit / IC?
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
What does a battery protection circuit do?
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
Do all batteries have built-in protections?
Not all cells have built-in protections and the responsibility for safety in its absence falls to the Battery Management System (BMS). Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high.
What is the difference between high voltage and low voltage protection?
High voltage is easy! Simply remove the source of charge and the voltage will fall back into specifications and come back on. Low voltage, on the other hand, can be a little tricky sometimes. Low voltage protection or UVP (Under Voltage Protection) just needs the voltage brought back up by recharging the battery. Easy right?
How do you protect a battery from high voltage and low voltage?
Lastly is voltage protection - the battery is both protected from high and low voltage. High voltage is easy! Simply remove the source of charge and the voltage will fall back into specifications and come back on. Low voltage, on the other hand, can be a little tricky sometimes.
