本文提出了一种自供电接口电路与混合储能单元（ESU）的动能收集应用，使用超级电容器和锂聚合物电池（LPB）。超级电容和充电管理芯片的使用延长了电池的寿命。另一方面，锂聚合物电池（LPB）减少了由于漏电流和等效串联电阻（ESR）造成的能量损失。本文还展示了能量收集供电的智能篮球硬件模块的ESU的特性。在提出电源管理电路之前，首先介绍了动能采集测试系统（KETS），并利用该系统对冲击式电磁能量采集器的发电特性进行了测试。优化的电磁振动采集器（EVH）在低频（<10 Hz）下可产生4.0 mW的功率。
This paper presents a self-power interface circuit with hybrid energy storage unit (ESU) for kinetic energy harvesting applications using super-capacitor and Li-polymer battery (LPB). The use of super-capacitor and charge management chip extend the battery's life. On the other hand, the Li-polymer battery (LPB) reduce the energy loss due to leakage current and equivalent series resistance (ESR). The paper also shows the characterizations of the ESUs for energy harvesting powered smart basketball hardware module. Before the power management circuit proposed, the kinetic energy-harvesting test system (KETS) is presented and used to evaluate the power generation characteristics of electromagnetic energy harvester with impact-type vibration. The optimized electromagnetic vibration harvester (EVH) can produce a power of 4.0 mW at low frequencies (< 10Hz).
