The invention discloses a portable power unit and a crane thereof, a battery is provided with a temperature alarm module, the battery is connected with a motor and a charging device through a circuit for storing and outputting electric energy, and the battery is connected with a radiator through a circuit; the hydraulic pump comprises at least one electric control variable pump and at least one gear pump; the hydraulic pump is connected with a crane hydraulic system through a hydraulic pipeline; the motor comprises a driving motor and converts electric energy output by the battery into mechanical energy used by the hydraulic pump; the charging device comprises a charging cable and a charger. The system can be used for a traditional fuel crane, the problems that a battery of a pure electric crane is high in price and high in cost are solved, and an electric control system for complex chassis driving and loading operation is not needed; a pure electric or plug-in working mode can be used, and the continuous working time can be effectively prolonged under the plug-in working condition compared with a pure electric crane; and a plug-in mode is used, so that the situation that the vehicle can be charged only after parking, flameout and stop working is avoided.

    本发明公开了一种便携式动力单元及其起重机,电池设有温度报警模块,电池通过电路与电机、充电装置连接用于存储和输出电能,电池通过电路与散热器连接;液压泵包括至少1个电控变量泵及至少1个齿轮泵,液压泵通过液压管路与起重机液压系统连接;电机包括1个驱动电机,电机将电池输出的电能转化为液压泵使用的机械能;充电装置包括充电线缆与充电器。本发明可以用于传统燃油起重机,克服纯电动起重机电池价格昂贵、成本高的问题,也不需要复杂的底盘行驶和上车作业的电控系统;可以使用纯电或插电工作模式,插电工况下相较于纯电动起重机可以有效提升可连续工作时间;使用插电,避免了车辆必须驻车熄火停止工作后才能进行充电。
