Description

具有电池容量分析功能的充电装置
技术领域
本发明涉及机电类，特别涉及一种具有电池容量分析功能的充电装置。
背景技术
如附图1及附图2所示，一般市面上常用的充电设备A，其功能在于连接电池A1进行充电，当充电机A2连接电池A1充电时，通过充电机A2本身的电路，并无法得知电池A1是否损坏、故障、老化或无法蓄电，因此，若欲针对电池A1的功能进行判断时，必须额外接设充电机A2及放电机A3，同时再计算电池A1放电所消耗的总功率，以得知电池A1功能是否正常，然而，通过额外接设的充电机A2及放电机A3，其在使用上不仅较为不便，且也会增加置放空间及成本，需要加以改进。
发明内容
本发明的目的在于提供一种具有电池容量分析功能的充电装置，解决了常用充电装置使用不便、增加置放空间及成本等问题。
本发明的技术方案是：该充电装置包含有控制单元、计算单元、显示单元、充电单元及放电单元，其中，该控制单元分别与充电单元及放电单元相连接，该充电单元及放电单元分别与电池连接，该放电单元与计算单元连接，该计算单元与显示单元连接；当充电单元连接电池进行充电时，经由控制单元判断电池的电力是否充饱，在充饱后停止充电同时再经由放电单元对电池放电，并经由控制单元控制，且在电池的电力耗尽后停止放电，使计算单元计算出电池的实际有效容量，同时再将计算出的实际有效容量数据经由显示单元显示后，以完成充电装置的电池容量分析及充电；其中，该显示单元可设为LCD液晶显示装置、LED发光二极管显示装置及数字型发光二极管及相关具有可供显示数据的装置；该充电装置还包括有记忆单元，与计算单元相连接，可在电池充放电后，进行容量记忆的功能；放电单元内设置的消耗负载可设为电阻、电晶体、MOS、电子装置、灯泡、马达等可消耗功率的负载；控制单元及计算单元等元件可整合成为模组及IC积体电路，以有效提高相关电路的连接及运用。
本发明的优点在于：利用充电装置内建的电池容量分析单元、控制单元及计算单元，可判断并精准换算出电池的容量；还可判断并分析电池好坏及实际有效容量，达到充放电检测功能的目的；在使用上较为方便且不增加置放空间及成本，实用性强。
附图说明：
图1为常用充电装置的方块图；
图2为常用充电装置的立体示意图；
图3为本发明的方块图之一；
图4为本发明的立体示意图之一；
图5为本发明的方块图之二；
图6为本发明的电路图；
图7为本发明的电路方块图。
具体实施方式：
如附图3至附图5所示，本发明充电装置B包括控制单元C、计算单元D、显示单元E、充电单元F及放电单元G，其中，充电装置B内建包含控制单元C，且该控制单元C对应于计算单元D，该控制单元C相对应充电装置B的显示单元E；
充电装置B包含充电单元F及放电单元G，且该充电单元F及放电单元G相对应电池H，该电池H相对应控制单元C的计算单元D及显示单元E；
当充电单元F连接电池H进行充电时，经由控制单元C判断电池H的电力是否充饱，在充饱后同时再经由放电单元G对电池H放电，并判断电池H电力耗尽后停止放电，使计算单元D换算出电池H消耗的总功率；
如附图5所示，控制单元C的计算单元D，可判断并换算出电池H及放电单元G间所消耗的总功率，同时换算出的总功率数据可经由显示单元E显示后，再将连接充电装置B的电池H充电，以达到电池H充电的目的；
如附图4所示，充电装置B还包含电源导通单元I，且该电源导通单元I相对应电池H的导电端H1，使充电装置B可连接电池H以达到电池容量分析及充电功能的目的；又，该充电装置B还包括有一记忆单元J，可于电池H充电后，进行容量记忆的功能；
充电装置B的显示单元D可设为LCD液晶显示装置E1、LED发光二极管显示装置E2及相关具有可供显示电池总功率数据的装置。
如附图5至附图7所示，控制单元的Vo脚输出为1V，放电电流为1A，Vo电位经R2、R3分压后VT＝10mV，假设此时流经R1的电流为0.5A，故Vc＝5mV，VT与Vc经OP比较后输出为Lo，使得Q1呈现OFF的状态，其Q1呈现OFF同时造成MOS1、MOS2同时为ON，会使待放电电流快速上升，当电流上升至1.1A时，VCC变为11mV，由于OP随时不断的将Vc与VT的电压值做比较放大，因此OP的输出变成Hi，使得Q1呈现ON，造成MOS1、MOS2同时为OFF，放电电流就快速下降；当电流下降至0.9A时Vc＝9mV，又使OP输出为Lo，Q1呈现OFF，MOS1、MOS2呈现ON，使电流又上升，因为OP不断的做比较，使得Q1也不断的ON、OFF，造成MOS1、MOS2也不断的ON、OFF，这样使得放电电流形成固定定电流，故将控制单元作一设定，以致当电池放电至某一电压值时就停止放电，同时将放电时间作一记录，以将放电时间乘以放电电流就是该电池的实际有效容量。
