The invention discloses a crane boom head battery charging method and device and a crane. The method comprises the steps that the state of a crane boom and the electric quantity of a boom head battery pack are judged; when the cargo boom is in the retraction state and the electric quantity of the boom head battery pack is smaller than a set value, the boom head battery pack is controlled to enter a charging mode; in the charging mode, a charging connector of the power management module is connected with a power interface arranged on the chassis through a charging cable in an inserted mode, and the power management module is connected with an arm head battery pack arranged on the head portion of the tail section arm. And when the cargo boom is in the retraction state and the electric quantity of the boom head battery pack is larger than a set value or the cargo boom is in the non-retraction state, the charging mode of the boom head battery pack is released. The charging interface and the charging connector are connected through the charging cable, compared with the mode that an external cable drum of the crane boom supplies power to the boom head element, the line abrasion risk in the crane transition and operation process can be reduced, and the system has the obvious advantage in weight.
本发明公开了一种起重机臂头电池充电方法、装置及起重机,该方法包括判断起重臂的状态和臂头电池组的电量;响应于起重臂在缩回状态,且臂头电池组的电量小于设定值时,控制臂头电池组进入充电模式;在充电模式,电源管理模块的充电接头和设置在底盘上的电源接口通过充电线缆插接连接,其中,电源管理模块和设置在末节臂头部上的臂头电池组相连接;响应于起重臂在缩回状态且臂头电池组的电量大于设定值时,或起重臂在非缩回状态时,使臂头电池组解除充电模式。本申请通过充电线缆连接充电接口和充电接头,相比起重臂外置电缆卷筒给臂头元件供电的方式,可以降低起重机转场及作业过程中线路磨损风险,且系统重量上具有明显优势。
