摘要

我们提出了一种用于锂离子电池(Lithium-ion battery)的磁场共振型无线电力传输系统。电池的传输效率随充电电流的变化而变化。该系统将DC/DC转换器置于一次侧和二次侧。该系统通过控制一次侧DC/DC来抑制二次侧负载变化引起的传输效率下降。实验表明，该系统仅抑制了4.4%的传输效率下降。与传统方法的16%的退化相比，这是一个显著的改进。因此，该系统既能实现蓄电池的最佳充电，又能提高大范围输出电流的传输效率。

An optimal wireless power transfer system for Lithium-ion battery charge

We propose a magnetic field resonance type wireless power transfer system for the Li-ion battery (Lithium-ion battery). The transmitting efficiency is changed by the changing of the charging current to the storage battery. The system places the DC/DC converter at both of the primary and secondary sides. This system suppresses the degradation of transmitting efficiency due to the secondary side load variation by controlling the primary side DC/DC. By experiments, this system suppressed only 4.4% degradation of transmitting efficiency. It is significant improvement from 16% degradation by conventional approaches. Thus, this system derives both of optimum charging to storage battery and improvement of the transmission efficiency for wide range of output current.
