无线能量传输技术是一种新型的电能传输方式，是指相对于传统的利用导线连接的电能传输方式而言，电能从电源到负载的一种没有直接电气接触的能量传输方式，解决了传统导线直接供电的缺陷，是一种安全有效的电能传输方法。目前无线能量传输通常使用补偿电容的工作方式使系统在发射端(原边)与接收端(副边)同时工作于谐振状态，以提高输出能力。前期实验发现，无线能量传输系统的效率受等效负载的影响，选取合适的等效负载可以改善系统的效率。基于此，研究了负载对于系统效率和频率分叉的影响，设计了一个负载自适应控制策略，能够提高系统的能量传输效率，并且保证不出现频率分叉现象。该研究将对无线能量传输系统的可靠设计具有重要指导意义。

Based on the Partnership for a New Generation of Vehicle (PNGV) model, the internal state variables of the battery are estimated based on the measured external variables. The experiment uses hybrid pulse power characterization (HPPC) method to obtain the lithium battery in the pulse loading and the transition process parameters. Finally, the PNGV equivalent model of the battery is simulated and analyzed by MATLAB/Simulink. The results show that the selected PNGV model has high precision and can simulate the charge and discharge characteristics of battery truly. The model parameters can be estimated accurately under fixed temperature and known SOC. The experimental results can provide a theoretical basis for internal state variable estimation of lithium batteries.

为了快速有效地实现串联锂离子单体电池间的能量均衡，提出了一种基于Cuk斩波电路的双向双层桥臂的蓄电池组均衡器。此均衡器根据电池组的充放电状态采取两种不同的均衡策略：当电池组处于充电状态时，电池组中具有最高荷电状态的单体电池通过Cuk斩波电路被快速均衡放电；当电池组处于放电或静置状态时，电池组中具有最低荷电状态的单体电池通过Cuk斩波电路被快速均衡充电。均衡器拓扑电路原理简单、均衡电流连续、均衡电流可控性强、均衡效率高。最后对此均衡器进行了仿真实验，证明了此方案的可行性。

The identification precision of model parameters would be affected by the amplitude of signal by using step-change current to identify battery parameters. In this paper, error analysis of this parameter identification method applied in battery dynamic models is carried out to address this issue. And a method to determine the amplitude of step-change current is proposed. Battery nonlinear characteristics and measure error caused by the detection devices are considered to identify the function between the relative error of parameters and the amplitude of step-change current. The amplitude determination procedure is given in this paper. Analysis and experiments verify the feasibility of the proposed method.

In order to meet the practical demand of the wireless charging for electric vehicles, a constant current control method is proposed. The model of the magnetic coupling resonance inductively coupled power transfer (ICPT) system based on LCL-S type is established, and its operating characteristics are analyzed. Then, according to the output characteristic curve of the secondary current and the transmission efficiency characteristic curve, the frequency range of the system is determined. And this interval is used as the frequency modulation area of the system constant current operation. The advantages and disadvantages of various power control methods are compared. Furthermore, a constant current control strategy is proposed, which is the combination of variable frequency control and phase shifting voltage regulation. Control program of the P feedback is designed. Through experiment, the constant current control effect is verified when the load is different. The experiment shows that the control strategy can realize the non-static difference and the fast response control without overshoot.
