How to protect a battery rack from overcurrents?Every battery rack requires adequate galvanically switching and protection against overcurrents caused by battery modules. Unlike in PV strings, the overcurrents caused by batteries can be very high according to the battery technology.
What is overcurrent protection?Overcurrent protection refers to the lithium battery in the power supply to the load, the current will change with the change of voltage and power, when the current is very high, it is easy to burn the protection board, battery, or equipment.
Why is battery overcurrent protection important?However, the widespread use of batteries has also brought about current problems, where the presence of overcurrents can lead to catastrophic accidents such as equipment failures, fires, and even explosions. Therefore, overcurrent protection has become a key element in ensuring the safety of battery applications.
Do lithium ion batteries have overcurrent protection?A similar issue presents itself when trying to incorporate overcurrent protection that is more sophisticated than a fuse, yet does not come bundled with unnecessary battery management functionality. Lithium-ion (Li-ion) and lithium polymer (LiPo) batteries have very similar electrical characteristics but differ in packaging.
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 an overcurrent protection trigger?Overcurrent protection trigger: When the battery protection board detects that the current has exceeded the set safety threshold, it will trigger the overcurrent protection mechanism to avoid damage to the battery and equipment caused by excessive current.
Each circuit design provides constant current charging followed by constant voltage charging algorithm with automatic charge termination and battery temperature monitoring.
