Overcurrent protection is crucial for battery safety as it helps prevent catastrophic accidents such as equipment failures, fires, and explosions. The widespread use of batteries has brought about current problems where the presence of overcurrents can lead to these incidents.
Overcurrent protection is a safety measure that prevents excessive current from flowing through a circuit. In the context of lithium batteries, it helps protect the battery, the protection board, and the connected equipment from damage due to high currents.
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.
Overcurrent protection in USB is a safety mechanism that activates when the current exceeds a predefined threshold. This prevents the device, such as a computer motherboard, from being damaged or catching fire.
Overcurrent protection helps reduce the generation of electronic waste and reduces the environmental pollution of e-waste. Frequent replacement or discarding of damaged electronic devices generates a large amount of electronic waste, which has a negative impact on the environment.
