一种智能镍氢电池充电器的设计

摘要

In view of problems that charger of Ni-MH batteries based on MAX713 is only used in charging for 1 ～16 Ni-MH batteries and exists virtual filling, the paper proposed a design scheme of intelligent charger of Ni-MH batteries which can charge for more than 16 Ni-MH batteries.The charger takes MAX713 as basis and uses serial way to link batteries, and is added timing detection function which can ensure fully filling of Ni-MH batteries through controlling relay by single-chip microcomputer.The actual application showed that the charger has certain practicability.%针对基于MAX713的镍氢电池充电器只能用于1～16节镍氢电池的充电、而且存在虚充满现象的问题,提出了一种可为16节以上镍氢电源充电的智能镍氢电池充电器的设计方案.该充电器以MAX713为基础,采用级联方式连接电池,并增加了定时检测功能,该功能通过单片机控制继电器来确保镍氢电池完全充满.实际应用表明,该充电器具有一定的实用性.
