现有第一种充电器， 其输入侧电路中设有一个输入口和一个充电输入电 路， 该输入口的电源端连接该充电输入电路的充电输入端， 该充电输入电路的 充电输出端用于接到所述电池的取电端， 从而形成一条取电电路以供所述电池 从接入到这一个输入口的变压器取电。该输入口的数据端连接该充电输入电路 的控流端， 使得该充电输入电路的充电电流不高于接入到该输入口的变压器的 额定电流， 以保证变压器不会过流损坏。

发明内容
本发明的目的是让充电器在保证所接入的变压器不会过流损坏的前提下 提高取电速率从而节省充电时间。
为此给出充电器， 包括电池、 输入侧电路和输出侧电路：

其特征是这样的取电电路有至少两条， 这些取电电路并列地输出到所述电 池的取电端。
本发明的取电电路有至少两条， 故可接入至少两个变压器， 通过这至少两 条取电电路来并列地向电池充电。 根据电流叠加的原理， 电池取电的总充电电 流为各取电电路的充电电流之和， 大于其中一条取电电路的充电电流， 故取电 速率高于只采用一条取电电路的现有技术， 节省了充电时间。 各条取电电路分 别根据所接入的变压器的额定电流对自身的充电输入电路进行限流， 保证所接 入的变压器不会过流损坏。

三条取电电路并列地输出到所述电池的取电端。 本实施例中， 三条取电电 路充电电压均为 5V。

编程控制器从输入口 2的数据端 D+、 D-读取到变压器 2的类型， 得知其 额定电流为 1.0A,据此向充电输入电路 2的控流端发出信号， 限制充电输入电 路 2的充电电流不高于 1.0A, 以保证变压器 2不会过流损坏。
编程控制器从输入口 3的数据端 D+、 D-得知输入口 3没有变压器接入， 就无需对充电输入电路 3进行电流控制。
正常情况下， 第一条取电电路以变压器 1的额定电流 2.1A向所述电池充 电， 第二条取电电路以变压器 2的额定电流 1.0A向所述电池充电， 第三条取 电电路无充电电流， 根据电流叠加的原理， 电池取电的总充电电流为 2.1A+1.0A+0=3.1A。可见， 在保证所接入的变压器 1和变压器 2不会过流损坏 的前提下， 本实施例的充电器取电速率高于现有的充电器。
