The same reference numerals in the drawings denote the same or similar elements. The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustrative." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or preferred. In addition, numerous specific details are set forth in the Detailed Description of the <RTIgt; However, it will be understood by those skilled in the art that the present invention may be practiced without the specific details. In some instances, methods, means, components, and circuits that are well known to those skilled in the art are not described in detail in order to facilitate a
如图1所示，根据本发明的示例性实施例的可扩展的充电单元控制系统包括主控制单元、多个充电控制单元和CAN集线器。多个充电控制单元分别与主控制单元通信连接，每个充电控制单元之间彼此通信连接，并且充电控制单元与待充电对象对应连接。优选地，充电控制单元与主控制单元通过CAN总线通信连接。如图1所示，当充电控制单元扩展数量较多时，主控制单元与充电控制单元通过CAN集线器通信连接，以便进一步扩展充电控制单元的数量。在本发明中，不仅充电控制单元通过CAN总线通信连接主控制单元，充电控制单元与主控制单元之间也通过CAN总线通信连接，从而解决了在充电控制单元之间传输信息时需要先传输给主控制单元，然后再下发到目标充电控制单元的问题，节省了传递时间。当然，充电控制单元与主控制单元之间以及充电控制单元之间也可以通过本领域技术人员已知的其它通信连接方式连接。As shown in FIG. 1, an expandable charging unit control system according to an exemplary embodiment of the present invention includes a main control unit, a plurality of charging control units, and a CAN hub. A plurality of charging control units are respectively communicably connected to the main control unit, each charging control unit is in communication connection with each other, and the charging control unit is correspondingly connected with the object to be charged. Preferably, the charging control unit is communicatively coupled to the main control unit via a CAN bus. As shown in FIG. 1, when the number of charging control units is expanded, the main control unit and the charging control unit are communicably connected through the CAN hub to further expand the number of charging control units. In the present invention, not only the charging control unit is connected to the main control unit via the CAN bus communication, but also the charging control unit and the main control unit are also connected via the CAN bus, thereby solving the need to transmit to the charging control unit when transmitting information to the charging control unit. The main control unit is then delivered to the target charging control unit, saving delivery time. Of course, the charging control unit and the main control unit and between the charging control unit can also be connected by other communication connections known to those skilled in the art.
进一步，每个充电控制单元在主控制单元上具有独立的硬件地址。主控制单元为每个充电控制单元分配独立的硬件地址，即物理地址，该物理地址可以通过拨码方式实现，从而从硬件地址上区分开每个充电控制单元，解决了因每个电池包的ID相同而导致无法集中管理的问题，同时能够根据换电站的需要方便地增加或减少充电控制单元，进而增加 或减少充电终端以调整换电站的规模，实现了对充换电站的灵活管理和扩展。Further, each charging control unit has an independent hardware address on the main control unit. The main control unit assigns each charging control unit an independent hardware address, that is, a physical address, which can be realized by dialing, thereby distinguishing each charging control unit from the hardware address, and solving the problem of each battery pack. The same ID causes the problem of inability to be centrally managed, and at the same time, it is possible to conveniently increase or decrease the charging control unit according to the needs of the power station, thereby increasing Or reduce the charging terminal to adjust the scale of the power station, and realize the flexible management and expansion of the charging and replacing station.
特别地，待充电对象也通过CAN总线通信连接充电控制单元。在这里，待充电对象包括但不限于换电系统的电池包。当然，待充电对象还包括电动汽车、电动自行车等其他用电设备。In particular, the object to be charged is also connected to the charging control unit via a CAN bus. Here, the object to be charged includes, but is not limited to, a battery pack of the power exchange system. Of course, the object to be charged also includes other electric devices such as electric cars and electric bicycles.
电池包与充电控制单元相连接。当插接电池包时，电池包向充电控制单元发送关于电池包插接状况的信号，尤其是发送电池包已插接就位的信号，充电控制单元在接收到电池包已插接就位的信号后，才向电池包充电。电池包还向充电控制单元反馈电池充电信息，对电池包进行充电管理。在这里，电池充电信息包括电池的当前电荷量、已充电时间、预计剩余充电时间、电池的当前充电循环次数等与电池充电相关的信息。由此，本发明不仅解决了电池包充电时的插接管理问题，还解决了与多台车辆的电池管理系统(BMS)通信的问题。The battery pack is connected to the charging control unit. When the battery pack is inserted, the battery pack sends a signal to the charging control unit about the plugging status of the battery pack, in particular, a signal that the transmitting battery pack is plugged in, and the charging control unit receives the battery pack in place. After the signal, the battery pack is charged. The battery pack also feeds back the battery charging information to the charging control unit, and performs charging management on the battery pack. Here, the battery charging information includes information related to battery charging, such as the current charge amount of the battery, the charged time, the estimated remaining charging time, the current number of charging cycles of the battery, and the like. Thus, the present invention not only solves the problem of plugging management when charging a battery pack, but also solves the problem of communication with a battery management system (BMS) of a plurality of vehicles.
继续参阅图1，本发明的示例性实施例的充电单元控制系统还包括充电复用模块。充电复用模块与各个充电控制单元电连接，同时与主控制单元通信连接，待充电对象能够通过充电复用模块选择性地电连接到充电控制单元，充电复用模块用于实现充电控制单元的复用。特别地，充电复用模块是包括多个控制开关的控制模组，主控制单元通过控制所述多个控制开关来实现所述充电控制单元的复用。在应用中，例如当某个电池包充满电时，充电控制单元向主控制单元发送该充电控制单元可以复用的信号，主控制单元向充电复用模块发送该充电控制单元可以复用的信号，促使充电复用模块的控制模组闭合相应的控制开关，充电控制单元将电流输送到待充电对象。本领域技术人员能够理解的是，这种设置可以大幅度提高充电控制单元的利用率。With continued reference to FIG. 1, a charging unit control system of an exemplary embodiment of the present invention further includes a charging multiplexing module. The charging multiplexing module is electrically connected to each charging control unit and is in communication with the main control unit.

The control module of the charging multiplexing module is caused to close the corresponding control switch, and the charging control unit delivers the current to the object to be charged. Those skilled in the art will appreciate that such an arrangement can greatly increase the utilization of the charge control unit.
接着参阅图1，本发明的示例性实施例的充电单元控制系统还包括整流器，整流器布置在充电复用模块与待充电对象之间，分别与充电复用模块和待充电对象相连接。充电控制单元与整流器通信连接，优选通过CAN总线通信连接，以便调整整流器的输出电压和/或电流，满足待充电对象的要求。在图1所示的实施例中，充电控制单元控制整流器向与整流器连接的待充电对象充电。通过对充电控制单元的复用，实现了与各充电控制单元连接的相应整流器的复用，从而在不增加充电控制单 元和相应的整流器的个数的情形下实现了更高效地向待充电对象充电，同时提高了充电控制模块和整流器的使用效率。Referring next to Fig. 1, a charging unit control system of an exemplary embodiment of the present invention further includes a rectifier disposed between the charging multiplexing module and the object to be charged, respectively connected to the charging multiplexing module and the object to be charged.
