Description

一种电动车蓄电池充电器及其应用
技术领域
本发明涉及一种充电器,具体是一种电动车蓄电池充电器及其应用。
背景技术
随着电动车的普及,电动车充电技术也受到人们的关注。我国的电动车用动力蓄电池大多为铅酸蓄电池,蓄电池是将化学能直接转化成电能的一种装置,是按可再充电设计的电池,通过可逆的化学反应实现再充电,通常是指铅酸蓄电池,它是电池中的一种,属于二次电池。它的工作原理:充电时利用外部的电能使内部活性物质再生,把电能储存为化学能,需要放电时再次把化学能转换为电能输出,比如生活中常用的电动车等,这主要是由于铅酸蓄电池具有技术成熟、成本低、电池容量大、跟随负荷输出特性好、无记忆效应等优点,但是现有的很多电动车充电器都没有短路保护功能,安全性较低,有很大的火灾隐患。
发明内容
本发明的目的在于提供一种电动车蓄电池充电器及其应用,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:

作为本发明再进一步的方案:所述单向可控硅VS的G极通过电阻R5连接时基芯片U1引脚3,单向可控硅VS的K极分别连接三极管VT1发射极、时基芯片U1引脚1、电容C2另一端和二极管D1正极,二极管D1负极连接发光二极管LED1负极。
与现有技术相比,本发明的有益效果是:本发明电动车蓄电池充电器及其应用采用NE555作为控制元件,配合单向可控硅和三极管,电路结构简单,成本低,体积小,而且带有短路保护功能,非常实用。
附图说明
图1为电动车蓄电池充电器及其应用的电路图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1,本发明实施例中,一种电动车蓄电池充电器及其应用,包括电阻R1、电容C1、时基芯片U1、二极管D1、发光二极管LED1和三极管VT1,所述电阻R1一端分别连接电源VCC和二极管D4正极,电阻R1另一端分别连接发光二极管LED1正极、电阻R2、时基芯片U1引脚8和电阻R4,电阻R2另一端分别连接电位器RP1一端、电位器RP1滑片、二极管D3正极和时基芯片U1引脚7,二极管D3负极分别连接时基芯片U1引脚2、时基芯片U1引脚6、电容C1和电阻R3,电阻R3另一端连接电位器RP1另一端,电容C1另一端分别连接时基芯片U1引脚5和电容C2,所述电阻R4另一端连接发光二极管LED2正极,发光二极管LED2负极分别连接时基芯片U1引脚4和三极管VT1集电极,三极管VT1基极分别连接电容C3和二极管D2正极,二极管D2负极连接电阻R6,电阻R6另一端分别连接单向可控硅VS的A极和蓄电池E负极,蓄电池E正极连接二极管D4负极,所述单向可控硅VS的G极通过电阻R5连接时基芯片U1引脚3,单向可控硅VS的K极分别连接三极管VT1发射极、时基芯片U1引脚1、电容C2另一端和二极管D1正极,二极管D1负极连接发光二极管LED1负极;所述时基芯片U1为NE555。
本发明的工作原理是:请参阅图1,555时基电路与外接电阻、电容和电位器构成可控硅触发电路,接通电源后,C1、C2同时充电,NE555的5脚电位很快上升至2/3VDD,VDD为U1的供电电压,这时C1上的电压约为零,即2、6脚的电压稍大于2/3VDD,U1的输出端3脚为低电平,NE555内部的放电管饱和,即NE555的7脚为低电平,于是C1放电,使U1的2、5脚电位逐渐下降至1/3VDD时,U1的3脚输出高电平,由此形成振荡,U1的3脚的输出控制可控硅导通给蓄电池E充电,RP1可调节充电电流,当充电端出现短路时,VT1饱和,LED2发光管亮,NE555的强制复位端4脚电压约为零,触发电路关闭。
对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外,应当理解,虽然本说明书按照实施方式加以描述,但并非每个实施方式仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经适当组合,形成本领域技术人员可以理解的其他实施方式。
