考虑到纯电动客车电池充电的重要性，有必要提供一种双源无轨电车充电控制方法，可采用两种充电方式进行充电，保证车辆运行的里程，从而满足客户运营要求。
发明内容
本发明的目的在于提供一种双源无轨电车充电控制系统，根据电池充电方式不同，通过控制相应充电接触器的闭合和断开，实现双源无轨电车的智能充电，提高了双源无轨电车充电的安全性和可靠性。
为实现上述目的，本发明采用了以下技术方案：包括动力电池、充电枪及集电杆线网，所述动力电池的正极通过接触器K4与集电杆线网的正极连接，动力电池的负极通过接触器K1与集电杆线网的负极连接，所述充电枪的正极通过接触器K3与动力电池的正极连接，充电枪的负极通过接触器K2与动力电池的负极连接。
进一步的，所述接触器K1、K2与动力电池之间还连接有接触器K5。
进一步的，还包括集电杆控制器，所述集电杆控制器的输入端分别与集电杆线网的正、负极连接，其输出端与电池管理系统连接，电池管理系统与充电机连接。
进一步的，所述集电杆控制器的输出端通过CAN总线与电池管理系统连接。
进一步的，还包括电池散热空调及并联在电池散热空调两端的DC/DC转换器，所述电池散热空调并联在动力电池的两端。
由上述技术方案可知，本发明通过控制相应充电接触器的闭合和断开，实现双源无轨电车的智能充电，提高了双源无轨电车充电的安全性和可靠性。同时，当充电时，所述DC/DC工作，输出27V电源给整车低压系统供电，保证整车充电控制正常工作；当充电时，所述电池散热空调工作，给电池进行散热冷却，保证电池充电温度在正常范围，保证电池安全。

集电杆线网3充电时，集电杆控制器4检测到线网电压后，再闭合接触器K1和K5，此时集电杆控制器4与电池管理系统5通过CAN信息进行通讯，以判定充电方式。当电池需要充电枪充电时，电池管理系统5（BMS）通过接收到充电确认信号，再闭合接触器K5、K3和K2，此时BMS通过CAN信息与充电机与进行通讯，以判定充电方式和充电电流的大小。
本实施例还包括电池散热空调7及并联在电池散热空调7两端的DC/DC转换器6，电池散热空调7并联在动力电池1的两端。充电时，DC/DC转换器6工作，输出27V电源给整车低压系统供电，保证整车充电控制正常工作；同时电池散热空调工作，给电池进行散热冷却，保证电池充电温度在正常范围，进而保证电池安全。
当电池需要集电杆线网充电时，闭合接触器K4、K1、K5，通过集电杆线网给动力电池进行充电，当充电完成后，断开接触器K4、K1、K5；当电池需要充电枪充电时，闭合接触器K3、K2、K5，充电完成后，断开接触器K2、K3、K5。
本发明通过控制相应充电接触器的闭合和断开，实现双源无轨电车的智能充电，提高了双源无轨电车充电的安全性和可靠性。同时，当充电时，所述DC/DC工作，输出27V电源给整车低压系统供电，保证整车充电控制正常工作；当充电时，所述电池散热空调工作，给电池进行散热冷却，保证电池充电温度在正常范围，保证电池安全。
