Rapid battery replacement of an electric automobile can solve the problem of inconvenience caused by charging of the electric automobile to a user, and reliability and low cost are the basis of battery replacement development. The invention provides a method and a system for locking a replacement battery of the electric vehicle through an eccentric wheel rotating shaft, which can complete the installation and locking of the replacement battery through a power system of the electric vehicle, greatly improve the battery replacement speed and the connection reliability, and improve the locking strength. A method for controlling the position and the locking force in the locking process is provided, the locking state can be monitored even in the driving process, and secondary locking is carried out. And meanwhile, battery replacement equipment of a battery replacement station can be simplified, and the battery replacement cost is reduced.

    电动汽车电池快换,可以解决电动汽车充电给用户造成的不便,可靠和低成本是换电发展的基本。本发明是提供一种通过偏心轮转动轴解决电动汽车换电电池的锁止方法和系统,包括可以通过电动汽车自有的动力系统完成换电电池的安装锁紧,大大提高换电的速度和连接可靠性,可提高锁紧强度,提供了可以对锁紧过程进行位置和锁紧力的控制方法,即使在行驶过程中也可以对锁紧的状态进行监控,并进行二次的锁紧。同时可以简化换电站的换电设备,降低换电成本。
