一种新颖的密封铅酸蓄电池充电器的设计（Design of a novel charger for sealed lead-acid batteries） The design of a new sealed lead-acid battery charger Xu Bin 1, Wu Yongjun 2 (1. Second Artillery Engineering College Room 502, Shaanxi Xian 710025) (2. Fourth the Second Artillery Institute, Beijing 100085) Abstract: This paper introduces the design principle of a new sealed lead-acid battery charger, and gives the basic formula and method to determine the parameters of charging. That application in the test instrument of environmental parameters: the charger is simple and practical, stable and reliable performance. Keywords: lead-acid battery; charger; charging; charging Design of a New Sealed Lead-acid Battery Charger XU Bin, WU Yong-jun Abstract:The design principle of a new sealed lead-acid battery charger is introduced.The method to determine the electric parameters for the charger and their design equations are provided. The charger is used in the test instrument of environmental parameters. It is proved that charger is simple, feasible and stable. Keywords:Sealed lead-acid battery; Charger; Over charge; Float Charge CLC number: TM912 document code: A article number:(2003) 1 - 2005102 1 Introduction Sealed maintenance free lead-acid battery due to good sealing, no leakage, no pollution and other advantages, in recent years has been widely used at home and abroad. However, due to the special requirements of the charging technology can not adapt to the maintenance free battery and charging method is not correct, it is difficult to achieve the required cycle life. UC3906 as the charging chip sealed lead-acid battery, it has realized the control and detection of sealed lead-acid battery charging for the best. It is important to make a variety of switching voltage changes with the charger and battery voltage temperature coefficient, so that the sealed lead-acid battery in a wide temperature range can reach the best state of charge. The structure and working principle of 2 UC3906
