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.

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品和促销展示。随着数字媒体慢慢取代印刷媒体，他们已经开始投资数字商品和分销。CV工作室目前正在为他们的客户转向数字显示单元，使用锂离子（Li-ion）供电的电视显示器。挑战在于将数字内容传输到电池供电的租赁线，并且可以持续至少12小时。锂离子电池虽然被广泛使用，但对于能量存储来说是非常不经济的，大大超出了成本要求。锂离子电池组的循环寿命范围在1000和1500之间，充电状态（SOC）范围在40%和90%之间（线性电压范围）。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使用智能电力电子电池电压均衡器形式的实用方法来解决。
