Smart power electronic battery energy management system for Lithium-ion powered next-generation digital media display units

CV Studios是一家印刷解决方案公司，为加拿大主要零售商管理、设计和印刷广告宣传资料和促销展示。随着数字媒体逐渐取代印刷媒体，他们开始投资于数字商品和分销。CV Studios目前正在为他们的客户转向使用锂离子(Li-ion)供电的电视显示器的数字显示单元。挑战是将数字内容提供给由电池供电、可持续至少12小时的租赁线路。锂离子电池虽然被广泛使用，但在储能方面却非常不经济，远远超过了成本要求。锂离子电池组的循环寿命在1000到1500之间，荷电状态(SOC)在40%到90%(线性电压范围)之间。锂离子电池组的主要问题包括：循环寿命、日历寿命、能量密度、功率密度和安全性。这些问题将在本提案中以智能电力电子电池电压均衡器的形式使用实际方法来解决。

CV Studios is a print solutions company that manages, designs and prints advertising collateral and promotional displays for major Canadian retailers. As digital media slowly takes over for print, they have started investing into digital merchandising and distribution. CV Studios is currently moving towards digital display units for their customers, using Lithium-ion (Li-ion)-powered TV monitors. The challenge is to get digital content to the leaseline that is battery powered and can last at least 12 hours. Li-ion batteries, although popularly used, have been highly uneconomic for energy storage, overshooting cost requirements by a large margin. The cycle life of a Li-ion battery pack ranges between 1000 and 1500, for state-of-charge (SOC) range between 40% and 90% (linear voltage range). The main issues with Li-ion battery packs include: cycle life, calendar life, energy density, power density, and safety. These issues will be addressed in this proposal using a practical approach in the form of a smart power electronic cell voltage equalizer.
