【正文】 load outputs to maintain efficiency. 5. Conclusion Advances in advanced battery charging technology have been numerous, including the development of the battery conditioning concepts, intelligent fast charging, and pulse charging. Pulse charging bined with intelligent control yields many advantages over conventional methods in maintaining battery capacity as well as extending battery life. This paper proposes a new divide and conquer method to charge small sections of highcapacity battery pack, which was experimentally shown to be more efficient than charging the whole battery pack simultaneously. Applications of this new battery charging method are currently being explored. Future work includes testing out the proposed methods on real highcapacity batteries such as the hybridelectric motor used in automobiles.

Abstract This paper analyzes the potential of intelligent pulsecharging for largescale applications. A novel divide and conquer technique is developed to efficiently apply pulsecharging method in highcapacity battery pack applications. Experiments, which are conducted on a smallscale system, validate the effectiveness of the proposed charging method. 2. Introduction Having a reliable battery is possibly the biggest issue facing the advancement of wireless technology today. As the demand for battery power grows, the size of the battery pack gets bigger and charging techniques bee more plicated. The battery charging issue is ubiquitous in all electronics applications. It is clearly the limiting factor in the application area of autonomous mobile robotics. Like other areas of technology that work with autonomy and mobility of electronics, the challenge is to find a reliable battery package for the robots. In an effort to investigate this problem, a study was launched to look into current literature, to examine currently available technology in intelligent battery charging, and to explore new solutions of battery charging systems for largescale applications. This study enpasses two main parts. The first part covers an examination of three different intelligent charging methods through current literature and their current application. The second part of the study analyzes the principles and properties of intelligent pulsecharging. A conjecture is made that pulse charging can and should be applied in largescale applications. The unique contribution of this paper
