The invention discloses a battery replacing method and system for a railway vehicle and a battery management system, and the method comprises the steps: transmitting a battery replacing request to the railway vehicle when a battery pack needs to be replaced, so as to enable the railway vehicle to run to a battery replacing position; and the rail vehicle is controlled to enter a battery changing mode, so that a battery changing system of a battery changing position changes the battery pack, and before the battery pack is powered off, the battery management system stores current data information and historical discharging data information of the battery pack. Therefore, the obtained battery pack data information is stored in the battery management system in the battery pack, the battery management system can be replaced along with the battery pack, the battery pack data information does not need to be uploaded to an in-station management system through a wireless communication technology, and the problem that data transmitted through the wireless communication technology is little in the past is solved; and meanwhile, an in-station management system is simplified.

    本发明公开了一种轨道车辆的电池换电方法、系统及电池管理系统,其中换电方法包括:在确定电池包需要更换时,发送换电请求至轨道车辆以使轨道车辆行驶至换电位;控制轨道车辆进入换电模式,以便换电位的换电系统对电池包进行更换,其中在电池包断电前,电池管理系统存储电池包的当前数据信息和历史放电数据信息。由此,将获取的电池包数据信息储存在电池包内部的电池管理系统,且电池管理系统可随电池包一并被更换,无需将电池包数据信息通过无线通信技术上传至站内管理系统,解决了以往通过无线通信技术传输数据较少的问题,同时也简化了站内管理系统。
