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.
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.
When the battery reaches this voltage, the BMS will issue a request to reduce the charging current. What needs to be clear is that overvoltage protection and overcharge protection are two different things. If overvoltage protection is effectively implemented, the battery will not be overcharged.
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. This is usually done by detecting a BMS over voltage drop in the circuit or by using a current sensor. 2.
The principle of overheating protection is to try to keep the battery below 45℃ to avoid rapid aging. But when the ambient temperature is high in summer, the temperature rise during normal use will exceed 45°C, then there will be a temperature value that prevents excessive damage on the spot.
The voltage of a single cell in the battery pack exceeds the allowable voltage. According to the purpose of protection, the battery is only allowed to discharge and the charging relay is disconnected. Generally, the BMS will set some warning voltages within the allowable voltage.
