High Power Density Pulsating Power Electronics Systems for Fast Charging of Li-ion Batteries

在众多的电池供电系统中，包括移动的设备和汽车，快速充电是非常理想的功能，然而，现有的快速充电系统会导致电池的退化，从而对其寿命产生负面影响。此外，现代电池充电系统通常体积庞大和/或效率低下。因此，它们不太适合集成在空间和重量受限的应用中，例如移动的和汽车。在大多数情况下，基于电力电子转换器的充电器尺寸过大的主要原因是转换器的电抗元件（电感器和电容器），在移动的和汽车应用中，电感器通常是系统中体积最大的部件。本研究的目标是开发一种紧凑型电源，将能够提供快速充电，而不会对电池寿命产生负面影响，并能够适应日益严格的体积和重量要求。The supply供应will havea novel新颖architecture架构.它将基于混合电源转换概念，提供小体积和高功率处理效率（提供高功率密度），并将实施一种新的充电算法，提供快速充电而不会对电池寿命产生负面影响，由GBatteries开发。

In numerous battery-powered systems, including mobile devices and automotive fast charging is highly desirable feature.However, existing fast charging system cause degradation of the battery negatively affecting its lifetime. Also, the modern batterycharging systems are usually bulky and/or inefficient. As such they are not well suited for integration in space and weightconstrained applications such as mobile and automotive.In most cases the main contributor to the overly large size of the chargers, which are based on power electronics converters, arereactive components of the converters (inductors and capacitors), where in mobile and automotive applications the inductors areoften the bulkiest components of the systems.The goal of this research is to develop a compact power supply that will be able to provide fast charging without negativelyaffecting the battery lifetime and will be able to fit into increasingly stringent volume and weight requirements. The supply will havea novel architecture. It will be based on hybrid power conversion concept, providing small volume and high power processingefficiency (providing high power density), and will be implementing a novel charging algorithm that provides fast charging withoutnegatively affecting battery life time, developed by GBattteries.
