Abstract

This paper proposes a multicell-to-multicell (MC2MC) equalizer based on the half-bridge bipolar-resonant LC converter (HBBRLCC), which collects energy from the consecutive more-charged cells (high-voltage group) through the positive and negative polarity selection switch matrix and the half-bridge switch matrix, and then releases the energy to the consecutive less-charged cells (low-voltage group). The paper includes configuration of the proposed equalizer, the mathematical model and simulation comparison with conventional equalizers, highlighting the superior high-speed balancing performance and excellent balancing efficiency of the proposed equalizer. An experimental prototype is built with four cells to verify the performance, and the balancing efficiencies in different balancing modes range from 81.45% to 87.62% with an average balancing power of 1.454 W to 5.011 W.

基于半桥双极谐振LC变换器的多电池对多电池均衡器，具有更多的平衡模式

本文提出了一种基于半桥双极谐振LC变换器(HBBRLCC)的多电池到多电池(MC2MC)均衡器，该均衡器通过正负极性选择开关矩阵和半桥开关矩阵从连续的高电荷电池(高压组)中收集能量，然后将能量释放到连续的低电荷电池(低压组)中。文中介绍了该均衡器的结构、数学模型以及与传统均衡器的仿真比较，突出了该均衡器优越的高速均衡性能和优异的均衡效率。实验结果表明，不同平衡模式下的平衡效率为81.45% ~ 87.62%，平均平衡功率为1.454 ~ 5.011 W。

期刊介绍： An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include: - Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.) - Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.) - Electromagnetic theory - Microwave and millimeter-wave devices, circuits, and modules - THz devices, circuits and modules - Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials) - Integrated circuits (memory, logic, analog, RF, sensor) - Power devices and circuits - Micro- or nano-electromechanical systems - Circuits and modules for storage - Superconducting electronics - Energy harvesting devices, circuits and modules - Circuits and modules for electronic displays - Circuits and modules for electronic instrumentation - Devices, circuits and modules for IoT and biomedical applications
