碩士 === 國立高雄應用科技大學 === 工業工程與管理系碩士在職專班 === 101 === In recent years, lithium-ion batteries have been applied to many power tools, outdoor products and electric vehicles. More and more devices and equipments originally powered by petroleum have been replaced by lithium-ion batteries gradually. The requirement of battery capacity is also getting bigger and bigger, and which means the weight of a single battery pack will be getting heavier to fulfill the needs. Those battery packs with high capacity and heavy weight are considered as “high power batteries.” Along with the increasing demand of high power batteries, more and more manufacturers originally involved with commodity battery pack industry have put resources on developing and producing the high power batteries. The first bottleneck is usually the decrease of production efficiency caused by the heavy weight of high power batteries. Therefore, the weight issue is always the first challenge that manufacturers need to face when they start the high power battery production. The focus of this research is to find solutions to solve the inefficiency of production of high power batteries. First, the production procedures are analyzed and segmented. Then, the best approach is selected and stopwatch timing method is used to conclude the standard time and learn the time saved by automatic production systems. Cost benefit analysis is conducted based on the previous outcome to conclude the research. This thesis has illustrated the efficiency of automatic production systems and concluded that the spending on the capital investments can be recovered within a short time by improving the production efficiency and continuously having better profit in return. The outcome can be a practicable reference for the manufacturers planning to implement automatic production systems, especially for the production of high power batteries.
