附图说明
下面， 参照附图， 对于熟悉本技术领域的人员而言， 从对本发明方法的详细描述 中， 本发明的上述和其他目的、 特征和优点将显而易见。 图 1为本发明的系统组成框图。 具体实施方式
如图 1所示， 本发明的用于公交车的超级电容充电系统是在传统的充电电动车基 础上做出的改进， 将传统的蓄电池充电改为大超级电容组充电， 并配合该充电超级电 容加入相关其它组成。
本发明主要包括：超级电容组 11、 调速器 12、 电动机 13、 快速充电器 14、 受电弓 15、 显示模块 16、 控制模块 17以及踏板检测单元 8等。
其中受电弓 15设置在电源触线和快速充电器 14之间， 在一定条件下接通充电电 路。 受电弓 15、 快速充电器 14组成超级电容组 11的一个主充电电路。
除上述主充电电路外， 本充电系统还包括了传感器 63， 用来实时检测超级电容组 11的温度、 电流和电压等参数情况， 并将有关参数送入控制模块 17后由显示模块 16 显示出来。
控制模块 17将传感器 63提供的参数与设定参数进行比较， 如果当前超级电容组 11 的温度超过设定值， 则控制执行单元 62进行降温处理。
当超级电容组 11工作一段时间后，控制模块 17检测到超级电容组 11中某个超级电 容的当前电流或电压达不到预定值， 此时， 如果车辆仍处于加速或制动情况下， 此时 充电将损坏快速充电器 14， 因此并不能进行辅助充电。 只有当踏板检测模块 18没有检 测到任何踏板信号， 即表面车辆处于停止或自由滑行状态下， 控制模块 17通过执行单 元 62使辅助电源单元 61对该超级电容进行补充电。因为超级电容组 11中每个超级电容 对应一个执行单元和一个辅助电源单元，所以控制模块 17可以控制执行单元 62进行单 个超级电容温度冷却或充电， 以确保超级电容组 11的每个超级电容都保持设定的正常 工作状态。 通常， 辅助电源单元 61通常采用 24V直流电源， 超级电容组 11中的超级电 容数为 15个。
此外， 为了保证主充电电路的充电安全性， 还可以通过控制模块 17实现对快速充 电器 14的控制。 '
下面详细说明本发明的用于公交车的超级电容充电系统的工作过程。
主充电电路的工作有两种情况： 一、 当公交车处于公交车总站时， 此时处于未行 驶状态， 通过主充电电路进行充电； 二、 在公交车停靠站、 乘客上下车时， 可伸缩受 电弓 15伸出与公交电车充电候车站充电电源电源触线对接， 以大电 向超级电容组 11 充电， 充电结束后可伸缩受电弓 15收回； 当公交车处于行驶或刹车状态下， 而且加速踏板和制动踏板均未动作， 即踏板检 测模块 18没有检测到踏板动作信号， 此时， 传感器 63检测到了超级电容组 11的充电温 度过高，由控制模块 17通过执行单元 62进行降温，以避免超级电容组继续充电被击穿。 由于超级电容组 11充电完成后即开始放电， 当车辆行驶一定时间， 传感器 63检测到超 级电容组 11中某单个超级电容的电压或电流未达到设定值，控制模块 17通过执行单元 62控制辅助电源单元 61对该单个超级电容进行充电。
此外， 为了保证主充电电路的安全性和可靠性， 还可以通过控制模块 17根据要求 控制快速充电器 14的充放电时间。
下面结合附图对调速器 12的工作情况简单进行说明。
调速器 12包括速度控制模块 21、 再生制动控制模块 22和电流反馈模块 23， 其中速 度控制模块 21接收超级电容组 11提供的电源进行工作， 此外， 该速度控制模块 21还受 踏板检测模块 18的控制。 下面具体说明其工作过程- 当踏板有动作， 即踏板检测模块 18传输一信号给速度控制模块 21， 该模块 21中含 有大功率器件 （IGBT) ， 通过控制该器件的导通和关断， 最终改变传送给电动机 13 的输入电压变化， 电动机 13带动固定速比差速器 19旋转。
同时， 电流反馈模块 23将电动机 13的速度釆用电流的形式反馈给速度控制模块 21， 起到恒流作用， 使车辆运行更加平稳。
在制动状态下， 电动机 13变为发电机， 发出的电压由再生制动控制模块 22送入速 度控制模块 21中， 由 IGBT进行调节， 调节后送至超级电容组 11中， 将此能量由超级电 容组 11回收。
受电弓检测模块 51是为了检测受电弓 15的位置，如果受电弓 15与电源触线处于接 触的充电状态， 受电弓检测模块 51通过速度控制模块 21使电动机 3处于安全的锁死状 态， 防止司机误操作， 发生危险。
超级电容超级电容调速器 12与电动机 13具有两种不同组合， 组合 1为直流斩波调 速器与直流电动机， 组合 2为交流变频调速器与交流电动机。 超级电容组 11的充电电 流为 50 400A， 工作电流为 (Γ300Α。 可伸缩受电弓 15伸缩量为 0~3000
