基于陶瓷压电效应的轮胎压力发电系统模型设计

摘要

the piezoelectric ceramic element is embedded in the automobile tire , the mechanical energy of the motor is converted into electrical energy by the positive piezoelectric effect of the ceramic element, and the electric energy of the super capacitor is transferred to the battery by the high efficiency of the switch integrated voltage regulator. The model design of tire pressure power generation system should be based on the improvement of the mechanical and electrical energy conversion efficiency and the loss of power transmission.%将压电陶瓷元件嵌入汽车轮胎中,利用陶瓷元件的正压电效应使汽车行驶时的无效机械能转换成电能,预先积聚存储在超级电容中;再利用高效率的开关集成稳压器对电瓶进行恒压充电,将超级电容中的电能转移到电瓶中.轮胎压力发电系统模型设计,要以提高发电单元机电能量转换效率和减小电能传输损失为核心.
