The invention relates to an expressway two-side direct-current mutual-aid type electric vehicle charging system which comprises MW-level charging stations arranged in service areas on the two sides of an expressway, the two MW-level charging stations are connected through a true bipolar direct-current bus, an energy mutual-aid line is erected on the true bipolar direct-current bus, and the energy mutual-aid line is connected with the MW-level charging stations. The energy mutual assistance line comprises a positive-negative-zero direct current mutual assistance line and a change-over switch thereof, the change-over switch is connected to the energy management platform, and the energy management platform is used for monitoring the running state of the MW-level charging station in real time and correspondingly controlling the working states of the MW-level charging station and the change-over switch. Therefore, mutual aid sharing of direct current side energy between service areas on two sides of the expressway is realized. Compared with the prior art, the high-power charging requirement can be met, multiple interconnection and mutual aid modes between the two sides of the expressway are achieved, more efficient and more reliable energy transmission is provided according to different energy mutual aid requirements and possible fault conditions, and the working flexibility and reliability of the system are effectively improved.

    本发明涉及一种高速公路两侧直流互济型电动汽车充电系统,包括设置于高速公路两侧服务区内的MW级充电站,其中,两个MW级充电站之间通过真双极直流母线相连接,真双极直流母线上架设有能量互济线,能量互济线包括正‑负‑零的直流互济线及其切换开关,切换开关连接至能量管理平台,能量管理平台用于实时监控MW级充电站的运行状态,并相应控制MW级充电站和切换开关的工作状态,以实现高速公路两侧服务区之间直流侧能量的互济共享。与现有技术相比,本发明能够满足大功率的充电需求、实现高速公路两侧之间多种互联互济的模式、根据不同的能量互济需求和可能存在的故障情况提供更高效更可靠的能量传输,有效提高系统工作灵活性及可靠性。
