Electric loader control method and electric loader
The invention belongs to the technical field of electric loaders, and discloses an electric loader control method and an electric loader, when the residual electric quantity of a power battery is larger than preset electric quantity, a hydraulic motor is controlled to work, and the electric quantity of the power battery is consumed. In order to guarantee the walking safety of the electric loader, a control oil way for connecting a hydraulic pump and a working part needs to be controlled to be disconnected, in the process, the working part does not work, a hydraulic system is in a pressure building state, oil in an overflow oil way overflows to a hydraulic oil tank through an overflow valve, and the safety of the hydraulic system is guaranteed. The redundant electric quantity of the power battery is consumed through the hydraulic system, and the overcharge phenomenon of the power battery is avoided. The structure of the whole machine does not need to be changed, additional hardware does not need to be added, the cost is kept unchanged, and the overcharge phenomenon of the power battery can be avoided only through control logic; the existing operation habit does not need to be changed in operation, the operation pressure of operators is reduced, and the operation is safer and more reliable.
本发明属于电动装载机技术领域，公开了一种电动装载机控制方法及电动装载机，动力电池的剩余电量大于预设电量时，控制液压电机工作，消耗动力电池的电量。为了保证电动装载机的行走安全性，需控制连接液压泵和工作部件的控制油路断开，在这一过程中工作部件不工作，使液压系统处于憋压状态，溢流油路内的油液将通过溢流阀溢流至液压油箱，以保证液压系统的安全性，实现通过液压系统消耗掉动力电池多余的电量，避免动力电池出现过充现象。无需改变整机结构，不需增加额外硬件，成本上保持不变，仅通过控制逻辑即可避免动力电池出现过充现象；在操作上不用改变现有的操作习惯，降低了操作人员的作业压力，更加安全可靠。
