Monitoring a 48-V lithium ion battery can be achieved using the TLV9022 device in combination with the TL431 shunt reference. The TLV9022 is a dual-channel, open-drain comparator that will be used to implement overcurrent and undervoltage protection. This comparator was selected for its low-input offset voltage and fast response time.
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.

Here is how the battery protection board works for overcurrent protection: 1. Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit.
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.
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.
a. Current disconnect: One of the most common responses to an overcurrent is to disconnect the battery charging or discharging circuits. The BMS can quickly stop the flow of current by disconnecting the associated relay or transistor.
The following is the working principle of BMS for overcurrent protection: 1. Current monitoring: The BMS employs current sensors for actively monitoring the real-time current within the battery pack. These sensors are typically constructed based on the principle of current Hall effect or resistance.
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.
