Application

This advanced battery - related technology is extensively employed in a plethora of fields and diverse scenarios. For instance, in electric bicycles, it powers daily commutes and short - distance travels, ensuring a smooth and reliable ride. Two - wheeled and three - wheeled vehicles rely on it for efficient operation, whether for personal use or in delivery services. AGVs (Automated Guided Vehicles) and robots utilize it for continuous and stable energy supply during their tasks. Portable power supplies benefit from its high - performance characteristics, while RV energy storage and low - speed four - wheeled vehicles demand its stability for long - term use.

These application scenarios all have stringent requirements for battery safety and stability. To meet these demands, the hardware protection board offers crucial functions such as overvoltage protection, which shields the battery from excessive voltage that could cause damage. Undervoltage protection ensures the battery doesn't discharge too low, maintaining its lifespan. Overcurrent protection prevents over - current situations that might otherwise harm the battery. All these functions work in tandem to ensure the battery can operate normally under various working conditions.
