进一步地，电机模块具体包括水洗电机28、回转电机30、风冷电机32及搅拌电机34、臂架泵电机26、主油泵电机24，通过上述电机的作用，从而实现泵车1对物料的水洗、回转、风冷及搅拌等功能，以保证泵车的正常工作；进一步地，将主油泵20、臂架泵22改为电驱动，提高整机的工作效率。具体地，水洗电机28用于驱动水洗泵，回转电机30通过回转减速器驱动泵车的转台回转，风冷电机32用于驱动风扇，从而为液压有冷却散热，搅拌电机32通过搅拌减速器驱动泵车料斗内的搅拌机构旋转，臂架泵电机26用于驱动臂架泵22运行进而驱动泵车各节臂架的展开与折叠， 主油泵电机24用于驱动主油泵20运行。本申请所提供的泵车1通过电池包12和供电接口，实现了泵车1整机的功能结构均为纯电驱动，进一步地提高了泵车1的整机工作效率，最终达到降低泵车1能耗，提升性能参数的目的。
在上述实施例中，优选地，还包括：电机控制器，电机控制器分别与电池包12、供电接口及电机模块相连接。
在该实施例中，将电机控制器分别与电池包12、述发电机及电机模块相连接，以保证对泵车1的精准控制和使用性能的稳定性。
在上述任一实施例中，优选地，还包括：变压器和逆变器，电池包12经变压器和逆变器与电机模块相连接。
在该实施例中，通过设置变压器将电池包12的输出电流进行电压调节，以保证充电安全。具体为，电池包12的输出电路经过变压器后输出与电机需求电压一致的电源，驱动水洗、转台等功能的电机运行，设置逆变器，可以将直流电变成交流电，而交流电机的价格相对于直流电机更便宜，因此可以降低泵车的成本。
在上述任一实施例中，优选地，还包括：第一整流器，供电接口经第一整流器与电池包12相连接。

在该实施例中，电池包12为驱动电机14提供动力，带动电机运行，通过传动轴16将输出动力传递至底盘的行驶车桥，以驱动车辆行驶。进一 步地，电池包12为高能量密度大容量的电池包12，作为整车唯一动力来源，驱动车辆行驶。另外，还可以通过驱动电机直接驱动泵车的每个车轮，从而减少传动轴和车娇的结构，此时，为了提高扭矩，可以在驱动电机与车轮之间增设减速机。当然，也可以车桥结构，对于同一轴的车轮(如后轮)用同一个驱动电机驱动，中间还可以增加主减速器和差速器等结构。
在上述任一实施例中，优选地，还包括：变速箱，变速箱与驱动电机14的输出端相连接，变速箱的输出端与传动轴16相连接。
在该实施例中，通过设置变速箱，实现对车辆行驶速度的调节。

在该实施例中，发电机的输入端与发动机相连接，发电机的输出端可以经整流器与电池包相连，或者经过整流器、逆变器后与电机模块相连接，使得发动机可以带动发电机发电，发电机所产生的电流经过整流后可为电池包充电，也可直接驱动电机模块工作，实现电机模块相应功能。
在上述任一实施例中，优选地，还包括：发动机；液压泵，液压泵与发动机相连接；马达，马达的液压油输入端与液压泵相连接；发电机，发电机与马达的动力输出端相连接，发电机的电力输出端与电池包12相连接。

上述两种方案中，通过增设发动机，当电池包的电量不足时，可以通过发动机发电以满足行驶和施工，对于不方便供电的施工场所，具有显著的意义。
具体实施例中，通过设置发电系统与电池包相连接，实现对电池包的实时充电，以保证泵车1的工作效率。具体地，发电系统包括发电机和与发电机相连接的动力装置，进一步地，动力装置可以为发动机，或有发动机驱动的液压泵和马达，具体并不局限于此。
在上述任一实施例中，优选地，供电接口设置有与充电桩连接的接口。
在该实施例中，供电接口设置有与充电桩连接的接口，以保证整车电 力的及时供应，适用范围广。外部电源经过车载充电口，经整流器后，为整车电池包12充电，同时驱动水洗、转台旋转、风冷、搅拌、臂架泵22、主油泵20电机工作。
