AI Technical Summary
Existing noise control solutions for charging piles cannot achieve precise and flexible noise control while ensuring the safety of equipment heat dissipation, leading to sudden noise changes, frequent start-stop cycles, or overheating risks.
A noise meter is used to obtain the noise coefficient. The noise control system is started by comparing the noise coefficient with a preset threshold. The first PID loop outputs the total heat dissipation capacity requirement value, and the second PID loop adjusts the charging power and fan speed. The weights are dynamically adjusted in combination with the ambient temperature to achieve multi-variable collaborative control.
It achieves a balance between commercial benefits and social responsibility, while ensuring charging efficiency and device safety, and dynamically optimizes noise and heat dissipation, thereby improving user experience and device reliability.
