Abstract

本实用新型提供一种锂电池包充电器，包括：电压输入端、电流控制模块以及电压输出端，该充电器还包括一个升压模块以及与升压模块、电压输入端相连接的电压检测模块。本实用新型的充电器不会引起锂电池包过充或者爆炸等危险。

Description

充电器
技术领域
本实用新型涉及一种充电器，特别地是一种用于给锂电池包充电的充电器。
背景技术
锂电池包因其轻便、容量大等优势在直流工具上的应用越来越广泛。用于给锂电池包充电的充电器通常为降压型的电池充电器，由于充电器输入电压高于锂电池包的最高电压，而降压型的电池包的电路结构决定了在降压模块开关管击穿或短路时输入端电压将会直接加在锂电池包的电池组上，此时锂电池组由于承受比标称电压还要高的充电电压而使得锂电池包存在过充甚至爆炸等危险。
发明内容
本实用新型的目的在于提供一种充电器，该充电器为升压型充电器并且是可提供输入电压检测保护的锂电池包充电器。
为了实现上述目的，本实用新型的锂电池包充电器，包括：电压输入端、电流控制模块以及电压输出端，充电器还包括一个升压模块以及与升压模块、电压输入端相连接的电压检测模块。
升压模块包括一个功率开关与储能电感、二极管、升压控制部分相连接。
电压检测模块包括电压检测装置以及电子开关
本实用新型的充电器不会引起锂电池包过充或者爆炸等危险。
附图说明
图1为本实用新型的优选实施方式的充电器的电路模块示意图；
具体实施方式
如图1所示，本实用新型的充电器的电路模块100包括电压输入端1、电流控制模块2以及电压输出端3，该充电器可为锂电池包的锂电池组6充电，充电器还包括一个升压模块4以及电压检测模块5。
升压模块4包括一个功率开关42与储能电感41、二极管43、升压控制部分44相连接。电压检测模块5包括电压检测装置51以及电子开关52。
功率开关42开启时，输入电压通过储能电感41、导通的功率开关42形成闭合回路，储能电感41存储能量；功率开关42断开时输入电压和储能电感感应电压通过二级管43输出到输出端3。
当输入端1的外接电压正常时，电压检测模块5开启电子开关52把电压送到升压模块4的输入端即电容C1的正极，加在升压模块4的电压使升压控制部分44开始工作，其通过控制功率开关42的通、断控制电压输出端3所需要的电压.如果升压模块4中的功率开关42被击穿或者短路，输入端1的输入电压通过储能电感41直接到地，充电器的输出端3输出电压几乎为0，锂电池组6不承受充电电压.
当输入端1的外接电压异常时，电压检测模块5的检测装置51检测到外接电压高于设定值时(比如错误的使用了充电器外部电压源或外部电压源损坏)，电压检测模块5关闭通路中的电子开关52从而切断电压，使得升压模块4的输入电压为0而停止工作，充电器几乎没有输出电压，有效地防止了锂电池组6因承受高压引起的过充等危险。
在本实施例中，无论是输入端1的外接电压异常还是功率开关42异常，充电器都能有效限制输出电压，避免锂电池组6因承受高压而可能产生的危险。
本实用新型并不限于上文及附图所揭示的具体方案，还可以有其他的方式。需要说明的是，以上实施例是非限制性的。除了该实施例外，凡本领域技术人员依常识进行的变换均落在本实用新型的保护范围内。
